Even a Category 4 hurricane doesn’t kill the mood for coastal fish – and that’s good news for all species, as well as for a multibillion-dollar recreational fishing industry. As extreme weather patterns threaten to bring more and larger storms to the Gulf Coast, new findings from the University of Texas at Austin’s Marine Science Institute show some important fish species are able to continue spawning even in a severe storm.
“This data gives us a little insight into how key species will handle changing and unpredictable conditions,” said Christopher Biggs, a Ph.D. candidate studying fisheries ecology and lead author on a paper published this week in Biology Letters. “They are somewhat preadapted to this. They regularly deal with changing situations. They might be better suited to handle the changing climate in the future.”
Biggs and a team of scientists from the University of Texas Marine Science Institute (UTMSI) and the University of Florida discovered that spotted seatrout kept spawning in late August 2017, even as the eye of Hurricane Harvey passed overhead, bringing with it windspeeds of up to 134 miles per hour and a storm surge of 8-10 feet.
“These fish are resilient and productive, even in the face of such a huge storm,” Biggs said. “On land, it was complete destruction, but these fish didn’t seem disturbed.”
Understanding the trout’s reproductive patterns and habitat needs is critical for the Texas coast, where sport fishing generates about $2 billion annually for the local economy, according to the Texas Parks and Wildlife Department. The murky waters of the Gulf of Mexico can make tracking the seatrout difficult, so the scientists study spawning patterns and behavior by placing underwater microphones in known spawning locations and leaving them there to record what follows.
Seatrout are actually not trout but a type of drum fish, and males make a distinct pulsing noise when spawning. The sound allows researchers to map and observe changes at spawning sites — information that state and federal agencies can use to help maintain healthy, sustainable fisheries.
In reviewing recordings captured in 2017, the scientists were surprised to find that the fish were spawning every day during the spawning season. And when Hurricane Harvey hit, they were more surprised that the storm did not disrupt the spawning. The only difference was that immediately after the storm, the fish began spawning 2.5 hours early. Over the course of the five days after the storm, the spawning patterns returned to normal.
The time difference was possibly due to water temperature differences brought on by the storm, Biggs noted, as the temperature returned to normal at about the same rate as the spawning patterns.
“Seatrout are an important part of the ecosystem,” Biggs said. “They are one of the most popular recreational fish. They are a top predator in the estuary and a favorite food for dolphins.”
The data coming out of the hurricane is a bright spot for the Marine Science Institute, which had several other projects severely disrupted by Harvey. Most of the buildings on the campus were damaged, equipment worth millions of dollars was damaged or destroyed, and many experiments were lost or set back as a result of the storm.
Repairs continue on the MSI campus. The Estuarine Research Center, one of three main laboratory buildings, reopened for scientists and students in September. The campus is expected to partially reopen to the public in summer 2019.
Brad Erisman, an assistant professor of marine science based at UTMSI, and Susan K. Lowerre-Barbieri of the University of Florida contributed to the research. The research was funded by the Texas State Aquarium WCCR Fund; a Harvey Weil Sportsman Conservationist Award; a Mission-Aransas NERR Graduate Research Assistantship; the Jack and Valerie Guenther Foundation; and J. and T. King.

The Chesapeake Bay’s overall “dead zone” turned out to be average in size this year, but abnormal weather through spring and summer made for some extreme conditions along the way, according to reports from Maryland and Virginia.
Researchers with the Virginia Institute of Marine Science determined via a computer model that the total volume of “hypoxic” water in the Bay, with oxygen levels low enough to stress fish, crabs and shellfish, was on par this year with that of 2017, taking up about 7 percent of the mainstem Chesapeake.
The Maryland Department of Natural Resources, using water-quality data gathered in sampling cruises from June through September, reported similar findings for the Maryland portion of the Bay. The DNR said that 17 percent of its waters had low dissolved oxygen levels — which matched the long-term average from 1985 through 2017.
But the DNR also found that abnormally wet weather through the first nine months of this year caused the low-oxygen zone in Maryland to gyrate in size from above-average in spring to near-record size by late June. It then plummeted to a record low in late July as a result of strong winds, followed by a rebound to higher than average in August and near-record again by late September.
"It’s fascinating how the hypoxic volume was so low in late July and so high in early September, but overall the hypoxic volume was basically the same as last year," said Mary Friedrichs, a VIMS research associate professor who co-developed the dead zone model. Originally developed using federal funding, the 3-D, real-time model draws on 30 years of water-quality data collected by the Chesapeake Bay Program. Daily wind and river-flow information is also part of the calculation.
Scientists had predicted the dead or hypoxic zone would be higher than average this year, based on high spring flows from the Susquehanna. The river, which normally furnishes half of the Chesapeake’s freshwater, was expected to pump unusually large amounts of nutrients into the Bay. Those nutrients — nitrogen and phosphorus — feed algae blooms, which die and decay, consuming oxygen in the deeper waters in the process.
The dead zone grows in warm weather, which encourages algae growth, and the general lack of wind during summer usually prevents much mixing of relatively oxygen-rich surface waters with the oxygen-poor depths.
Maryland experienced double the normal amount of rainfall in May, which the DNR said likely brought additional nutrients and sediment into the Bay and accounted for the larger than average dead zone in June. July also brought massive rainstorms in the Maryland and Pennsylvania portions of the Chesapeake watershed, resulting in near-record freshwater flows. But the high flows were accompanied by sustained winds of 20 knots that mixed oxygen into the Bay’s depths, just before the late July sampling cruise found a record-low size dead zone.
Winds abated and river flows eased up in August, and the volume of low-oxygen water grew again and exceeded the long-term average by late in the month. By mid-September, the zone had reached near-record size, the DNR reported.
The DNR said the fluctuation shows how weather can influence short-term conditions. Long term, it added, the dead zone has been shrinking, which a 2011 study attributed at least partly to pollution reduction efforts. High river flows pumping extra nutrients into the Bay, as they did this year, can buck that trend, the department noted.
While the VIMS model indicates that the Baywide total amount of low-oxygen water for 2018 was similar to last year, Friedrichs said the seasonal patterns were clearly different this year.
Low-oxygen waters averaged about 7 percent of the Bay’s entire volume during summer, with hypoxia more pronounced in Maryland, affecting nearly a fifth of its waters. This year, though, the dead zone occupied 14.4 percent of the Bay’s mainstem waters on July 5, Friedrichs said, but by July 26 — just three weeks later — had fallen to 0.14 the of mainstem water.
Friedrichs noted that low-oxygen conditions generally started earlier and lasted longer than in recent years. Other research suggests climate change could make such early onsets of the dead zone more common, she said.

Efforts to restore lost seagrasses in the Caloosahatchee River are proving promising, with planting taking hold, growing and flowering. The toxic algae bloom prevented monitoring of the plantings for months; however, surveys of them last week revealed the following:
Site 1: (furthest downstream site): Eelgrass was observed in four of the five GrowSAV Herbivory Exclusion Devices The protective coverings were not removed during the initial inspection, but most likely has grazed upon grass inside as well.
Site 2 & 3: Eight of the ten planting sites had very dense Eelgrass! The grass is expanding outside of the GrowSAV Herbivory Exclusion Devices and flowering inside. A total of two flowers appeared to have been germinated and are producing seeds. It is believe that this is the first time in the 21st century where there has been seed pods growing in the lower river!
Site 4: The one planting site (of five total) where the GrowSAV Herbivory Exclusion Devices was secured to the bottom had eelgrass growing. The other four sites were compromised by grazers.
Site 5 (furthest upstream site): Sparse eelgrass was present, though this area appears to be negatively impacted by water depth and grazing from Blue Crabs.
"Making progress in restoring the seed source for the lost seagrass beds in the tidal Caloosahatchee is a tremendous achievement. Seagrasses are the base of our aquatic food chain, supporting everything from crabs to endangered manatees. Continuing this project to learn how and where we can replenish them will have a significant impact in improving our ability to restore water quality and the ecology in the area." said Jennifer Hecker, Executive Director of the Charlotte Harbor National Estuary Program.
Water Resources Bill Goes To Trump With Big Win For Everglades Restoration
From the Fishing Wire
Water infrastructure package with benefits for fish, wildlife, and the outdoor recreation economy heads to president’s desk with bipartisan support
In a 99-1 vote, senators acted overwhelmingly in support of water resources and sent landmark legislation to the president’s desk that would expedite restoration efforts in the Everglades. The “America’s Water Infrastructure Act of 2018” (S. 3021) also takes important steps to advance nature-based infrastructure solutions—like restoring wetlands and dunes to reduce flood and storm damage—that are more cost-effective for the American taxpayer.
The House passed the bill unanimously last month.
“This is the biggest step forward for natural infrastructure that we’ve seen this Congress, and it builds on recent momentum to restore critical habitat and water quality in the Everglades,” says Whit Fosburgh, president and CEO of the Theodore Roosevelt Conservation Partnership. “American sportsmen and women should be heartened to see this level of bipartisanship for conservation, especially at a moment in the political calendar when both sides typically retreat to their own corners. We appreciate the leadership of Sen. Barrasso, Sen. Carper, Rep. Shuster, and Rep. DeFazio.”
The legislation advances two critical projects that will improve clean water flows throughout South Florida and supports the development of technologies to reduce harmful algal blooms that infamously killed fish across the state this summer. It will also provide for more advanced research on preventing the spread of invasive species like Asian carp and zebra mussels, whose growing populations threaten many popular fishing destinations.
“Today is a great day for America’s Everglades and the people of Florida. Construction can now begin on a reservoir south of Lake Okeechobee that is vital to reconnecting the lake to the Florida Keys. The economic benefits of this project cannot be overstated, as Florida’s economy depends on clean water, thriving fisheries and a robust real estate market,” says Eric Eikenberg, CEO of the Everglades Foundation.
Indeed, improving habitat and supporting predictable fishing opportunities will benefit Florida’s $2.9-billion recreational fishing industry.
“Passage of America’s Water Infrastructure Act is a monumental step in restoring the Everglades and providing clean water for Florida’s fisheries. This legislation is crucial to reducing the ongoing estuary discharges and algal blooms affecting the state, and we greatly appreciate the leadership of Florida’s Congressional Delegation in securing its passage. We look forward to working with Congress to ensure that sufficient funding is available to carry out the Act’s provisions,” says Kellie Ralston, Southeast Fisheries Policy Director of the American Sportfishing Association.
The bill also greenlights a feasibility study for habitat restoration projects in the Lower Mississippi River region. These projects could produce multiple benefits for fish and wildlife habitat and outdoor recreation opportunities across six states.
Another important provision of this legislation will help to give higher priority to natural and nature-based infrastructure solutions that reduce storm risks, enhance public safety, and conserve fish and wildlife habitat near Army Corps of Engineers project sites. Lawmakers supported requiring the Government Accountability Office to examine the costs and benefits that the Corps considers when authorizing projects. The current process likely underestimates the long-term cost savings of natural infrastructure projects, and bringing greater transparency to project deliberations is a positive step toward righting this imbalance.
On Fly in the Salt: American Saltwater Fly Fishing from the Surf to the Flats
The American Museum of Fly Fishing exhibit On Fly in the Salt: American Saltwater Fly Fishing from the Surf to the Flats, is going on the road. It travels to the National Sporting Library and Museum in Middleburg, VA (10/12/18-3/3/19), the Yale Peabody Museum of Natural History in New Haven, CT (5/6/19 – 10/13/19) and the Florida Keys History and Discovery Center in Islamorada, FL (11/10/19 – 2/29/20).
“There has never been a single exhibition that has compiled the comprehensive history of saltwater fly fishing,” says AMFF Executive Director Sarah Foster. “Since its early beginnings the saltwater discipline has graphed a continuing upward climb in popularity. In terms of new techniques, tackle development, cultivation of new fishing grounds, and advancements in biological and environmental knowledge, this branch of the sport may be unequalled in the overall history of fly fishing, and we are excited to bring this story to life through this exhibition”.
On Fly in the Salt: American Saltwater Fly Fishing from the Surf to the Flats traces the sport’s progress through interpretive display cases containing artifacts from the outstanding collection of the American Museum of Fly Fishing. Flies, reels, historical photographs, paintings along with an interactive video component containing interviews with some of saltwater fly fishing’s greatest legends illuminate the history of a pursuit that serves up a potpourri of mental and physical challenges that engender sheer, primal excitement for participants that navigate the glassy mosaics of clear water flats and the fierceness of the open ocean.
The exhibition timeline charts the sport in America from the late eighteenth century, with a nineteenth-century surge of literary accounts of adventurers seeking an ever-increasing variety of fascinating fish. In the 1920s and into the 1930s and 1940s pioneers like Tom Loving (Chesapeake Bay), Homer Rhodes (Everglades), and Harold
Gibbs (New England) were beginning to attract the attention of inquisitive anglers. These groundbreaking fly fishers began their own explorations, bringing tackle designed for trout and salmon to the saltwater bays, estuaries, surf, and even deeper marine zones. It is their work, along with technological advances, that led to the near-explosive development of the sport from the late 1950s through the 1970s, sometimes referred to as saltwater fly fishing’s golden decades.
In the latter half of the twentieth century, the saltwater angling community turned its attention to the fisheries and their environment. Earlier human observations documented the decline of some fish species, and these observations led to the formation of conservation organizations that used scientific techniques to confirm these interpretations and to make direct links between the environment, the actions of mankind, and the state of the fisheries.
The American Museum of Fly Fishing was founded in 1968 by a group of passionate anglers who wanted to ensure that the history of fly fishing was preserved as an important part of America’s culture, industry, and history. In the years since its formation, the Museum has collected, preserved, researched, and exhibited the world’s largest collection of angling artifacts and the world’s largest reference library of fly-fishing publications. AMFF is proud to trace the evolution of American saltwater fly fishing with this landmark exhibit.
The American Museum of Fly Fishing is open from 10AM – 4 PM, Tuesday – Sunday from May through October and Tuesday – Saturday from November through June. In celebration of its 50th Anniversary, admission is free on Fridays in 2018.
CB’s Saltwater Outfitters, 1249 Stickney Point Rd, Sarasota, FL has announced dates for their Orvis-Endorsed fly fishing schools for the upcoming fall through spring timeframe; Nov 17, 2018 and Jan 19, Feb. 23, Mar. 16, and Apr 13, 2019. Located on Siesta Key, named Best Beach in America, the schools will cover fly casting basics, line control, shooting line and the roll cast. Instructors, Capt. Rick Grassett and Capt. Ed Hurst, will also cover leader construction, fly selection and saltwater fly fishing techniques. The course, designed for beginning and intermediate fly casters, will focus on basics but also work with intermediate casters on correcting faults and improving casting skills. Cost for the schools, which will run from 8:30 AM to 2 PM, is $195 per person and includes the use of Orvis fly tackle and lunch. Contact CB’s Saltwater Outfitters at (941) 349-4400 or firstname.lastname@example.org to make reservations.
In collaboration with Bahamas National Trust and the local community in the East End. Grand Bahama Island, The Bonefish and Tarpon Trust has begun restoration of August Creek, blocked by a logging road since the 1950s. This restoration project is the first BTT has undertaken as part of its Bahamas Initiative, a nationwide collaborative effort to conserve the flats fishery. BTT designed a plan to reopen the creek and hired a local contractor to cut three strategic passes through the road. Almost immediately after the passes were completed, several species of fish, including bonefish, began utilizing the newly available habitat.
“Members of the East End fishing community have long lamented the loss of the upper reaches of August Creek,” said BTT’s Director of Science and Conservation Dr. Aaron Adams. “This strong local support made it easy to focus on this site as the first habitat restoration project. And, importantly, from an evaluation perspective, our research partners have data from this site prior to restoration. So as we gather data in the coming months, we’ll be able to evaluate the effectiveness of the project.”
BTT expanded its Bahamas Initiative this year to include a creek restoration component, which seeks to reconnect fragmented mangrove creek systems and restore both tidal flow and fish passage. Mangrove creek systems throughout The Bahamas have been impacted by past development, especially roads, reducing healthy habitat for bonefish. By restoring these fragmented systems, bonefish and other flats species will have greater access to healthy habitat.
“We appreciate our long and productive relationship with Bahamas National Trust and other partners who are concerned about conserving habitats so critical to the fishery,” said Jim McDuffie, BTT’s President and CEO. “This project, which follows years of collaboration aimed at protecting important bonefish habitats, extends our joint efforts to include restoration. This comprehensive focus on habitat bodes well for the future of the flats fishery in the Bahamas.”
With the first restoration project complete, BTT will begin the process of planning and fundraising for restoration on other creeks, contingent upon approval by The Bahamas.

Florida Governor Rick Scott has issued Executive Order 18-221 declaring a state of emergency due to impacts of red tide in Collier, Lee, Charlotte, Sarasota, Manatee, Hillsborough and Pinellas counties. Red tide is a naturally occurring algae that has been documented along Florida’s Gulf Coast since the 1840’s and occurs nearly every year.
Governor Scott said, “As Southwest Florida and the Tampa Bay area continues to feel the devastating impacts of red tide, we will continue taking an aggressive approach by using all available resources to help our local communities. Today, I am issuing an emergency declaration to provide significant funding and resources to the communities experiencing red tide so we can combat its terrible impacts. This includes making additional FWC biologists and scientists available to assist in clean-up and animal rescue efforts, more than $100,000 for Mote Marine Laboratory and $500,000 for VISIT FLORIDA to establish an emergency grant program to help local communities continue to bring in the visitors that support so many Florida families and businesses.
“In addition to the emergency order, I am also directing a further $900,000 in grants for Lee County to clean up impacts related to red tide – bringing total red tide grant funding for Lee County to more than $1.3 million. While we fight to learn more about this naturally-occurring phenomenon, we will continue to deploy all state resources and do everything possible to make sure that Gulf Coast residents are safe and area businesses can recover.”
Through the executive order, Governor Scott is providing significant state funding to local governments and research agencies, and allowing the rapid movement of resources to local communities in response to red tide impacts in Southwest Florida and the Tampa Bay area. Resources being deployed through the emergency order include:
· More than $100,000 in additional funding to Mote Marine Laboratory and Aquarium to increase its response to red tide impacts. This funding will help Mote Marine deploy additional scientists to assist local efforts to save animals affected by the naturally occurring red tide, including manatees, dolphins and sea turtles.
o Since 2011, Florida has invested more than $17.3 million through the Fish and Wildlife Research Institute (FWRI) in red tide research, including more than $5.5 million for a partnership with Mote Marine to study the causes of red tide.
· Making additional biologists and scientist available to support local government’s response to red tide and protect wildlife – this is in addition to the staff deployed by FWC at Governor Scott’s direction last week.
· Continuation of enhanced water monitoring and testing by the Department of Environmental Protection and FWC to give scientists the best possible data to work with.
· Direction for VISIT FLORIDA to begin developing a marketing campaign to assist Southwest Florida communities that will start following this year’s red tide blooms.
o VISIT FLORIDA will also create a $500,000 emergency grant program to assist local tourism development boards in counties affected by the naturally-occurring red tide.
· Additional aid from the Department of Economic Opportunity with business assistance, including interest free loans and an enhanced presence in Southwest Florida.
THE STATE OF FLORIDA HAS TAKEN THE FOLLOWING ACTIONS ON RED TIDE:
FISH AND WILDLIFE
· DEP and FWC have provided $100,000 in additional funding to Mote Marine to support efforts to rescue distressed marine animals, such as dolphins, sea turtles and manatees.
· Continuation of enhanced water monitoring and testing by the Department of Environmental Projection and FWC to give scientists the best possible data to work with.
· At Governor Scott’s direction, FWC has mobilized all available resources to mitigate naturally occurring red tide, and Executive Director Eric Sutton has waived rules through an executive order to expedite the removal of dead fish – regardless of applicable bag, size, or possession limits or of season or area closures – from shoreline, inshore or nearshore areas in the following counties: Collier, Lee, Charlotte, Sarasota, Manatee, Hillsborough and Pinellas.
· FWC law enforcement officers have been actively helping with animal rescue and red tide reconnaissance work.
· Additional biologists and scientist are available to support local government’s response to red tide and protect wildlife.
· FWC is operating the toll-free fish kill hotline. To report fish kills, contact the FWC Fish Kill Hotline at 800-636-0511 or submit a report online. Reports from this hotline help FWC researchers track and better understand the impact of red tide in Florida.
· FWC remains available to local agencies and partners in affected areas, including area business and tourism groups in Southwest Florida. Any local agency or group that has any questions or concerns can contact Kelly Richmond from the FWC at 727-502-4784.
· FWC continues to partner with the Florida Department of Health to advise residents and visitors of any potential health impacts. Residents and visitors can contact the DOH’s aquatic toxin experts at 850-245-4250 or contact their local health department for any concern about health safety.
· FWC’s Fish and Wildlife Research Institute and Mote Marine Laboratory work together to monitor Karenia brevis. This cooperative effort is designed to help mitigate the adverse impacts of red tide. This joint research program that includes red tide monitoring, research and public outreach and education has resulted in better tools and ongoing monitoring for red tides along the Gulf Coast.
· In partnership with FWC, the Collaboration for Prediction of Red Tides (CPR) at the University of South Florida offers a new Harmful Algal Bloom tracking tool that generates a 3.5-day forecast of the bloom trajectories.
· To protect public health, FWC’s Fish and Wildlife Research Institute’s Harmful Algal Bloom group closely monitors the status of K. brevis on Florida’s coasts, providing technical support to the Florida Department of Agriculture and Consumer Services, the agency that regulates approved shellfish harvesting areas.
· Since 2000, FWC’s Fish and Wildlife Research Institute established a Red Tide Offshore Monitoring Program, which is a volunteer program for citizens to help collect water samples from routine collection points and sites reported for suspected harmful algal blooms. The timely sampling by volunteers allows researchers to provide an early warning of offshore algal blooms and investigate reported events as they occur. The Program needs volunteers to collect samples from all coastal Florida counties. To view more information visit, Red Tide Offshore Monitoring Program or use the Volunteer SignUp Form.
· Under the direction of the emergency order issued by Governor Scott last month, DEP provided $1.3 million in grant funding to Lee County to clean up waterways affected by red tide. Lee County will use this additional funding to enhance the county’s efforts to clean local waterways from impacts caused by red tide.
· DEP continues to perform enhanced water testing, beach cleanup and public outreach, as well as the deployment of additional biologists to assist communities dealing with naturally occurring red tide.
HEALTH AND SAFETY
- Florida’s County Health Departments have taken the following actions:
- Lee County has posted red tide signs at more than 170 beach access points along the Lee County coastline. The red tide signs provide details on respiratory issues, health precautions, and resources for FWC, Mote Marine and current beach conditions. Environmental staff and County Health Department (CHD) leadership are in contact with city and county leadership, as well as local partners, in order to coordinate efforts and messaging. A press release detailing the effects of red tide and resources for mediation was sent out to local media partners. Additional resources, like website materials, social media posts, etc., have been shared with local partners for their use and distribution to their partners.
- Sarasota County environmental staff and CHD leadership have been in contact with city and county government and Visit Sarasota in order to coordinate messaging and provide template signage, website links, and creative materials. The CHD has also worked with the county in order to post signs at every beach, provided rack cards to the county and Mote for distribution.
- Charlotte County has posted signage along the beaches to advise visitors and tourists about the water conditions. The CHD has performed outreach to their community partners, as well as local government, to share informational resources, creative materials and public health messaging. They also are coordinating efforts and assisting their sister agencies, as needed.
BUSINESS AND INDUSTRY
- Governor Scott has directed VISIT FLORIDA to begin developing a marketing campaign to assist Southwest Florida communities that will start following this year’s red tide blooms.

In light of the recent disastrous water conditions along the east and west coasts of Florida, here are some techniques to insure that we as individuals or groups don’t become part of the problem.
SoLitude Lake Management
The summer season means warmth, sunshine and long days to enjoy swimming, boating, fishing, and spending time around the water. Unfortunately for many communities, the warm weather can also promote the growth of algae blooms in lakes and ponds used for recreation and drinking water. In community waterbodies, moderate amounts of algae can often signify the waterbody is in good health, but excess algae levels may indicate that the natural balance of the ecosystem has been compromised. Without swift and proper management, certain species of algae, like cyanobacteria, can begin producing harmful toxins. Following exposure or digestion of these toxins, humans and animals can experience skin rashes, liver and kidney toxicity, nervous system problems, respiratory complications and even death. Exposure to cyanobacteria also has suspected links to the development of degenerative diseases like ALS, Alzheimer’s and Parkinson’s disease.
Harmful Algal Blooms (HABs) can occur naturally, but have been a problem for decades due to the negative environmental impacts associated with urban development, mass agriculture and pollution. In recent years, private research and greater public awareness around the subject of HABs have brought nationwide attention to dangerous cyanobacteria blooms like the one currently plaguing Lake Okeechobee, the largest lake in Florida.
To help limit the growth of HABs in your community waterbodies, SOLitude Lake Management, an industry leader in lake, stormwater pond, wetland and fisheries management services, recommends the following sustainable measures to homeowners, golf courses, reservoirs and municipalities:
Effectively identify HABs
Accurate identification of harmful algal blooms is the first step to protect your family, your pets and surrounding wildlife from the negative effects of algal toxin exposure. Depending on the waterbody, a potentially harmful bloom may manifest in parallel streaks or clumped dots. Other blooms may look like spilled blue, green or white paint or turn the water a bright “pea soup” green. Keep an eye out for soupy or oily scum on the surface of the water.
Properly dispose of organic materials
Following yard work, leaves, grass and other debris should be bagged and removed from the property to prevent them from accumulating and decaying in the waterbody. When organic materials are allowed to decompose in freshwater resources, they release undesirable nutrients that are responsible for fueling nuisance plant and algae growth.
Establish a beneficial buffer
Steps should be taken to intercept runoff containing sediment, trash and other organic materials from entering lakes and ponds during rainstorms. Allow native flowering, deep-rooted vegetation to grow 3 to 5 feet from the edge of the lake or pond shoreline in a beautiful buffer.
Reduce excess nutrients
For lakes and ponds with chronic nutrient problems, the application of phosphorous-locking technologies, such as Phoslock and Alum, can make a noticeable impact. When applied by a licensed professional, these products work to rapidly remove free reactive phosphorous from the water column, improving water clarity and permanently reducing undesirable nutrients in the water column—so they can no longer contribute to harmful algae growth.
When paired with other nutrient-limiting strategies, floating fountains and submersed diffused aerators can help consistently circulate warm stagnant water and facilitate the conversion of phosphorous and nitrogen to nutrient forms that do not sustain algae as food.
Apply beneficial bacteria
Another way to limit algae’s food source is through the introduction of bacteria and enzymes, a process called biological augmentation. The beneficial bacteria can help consume additional pond nutrients that fuel nuisance algae blooms and help facilitate the degradation of the organic nutrient sources.
Regularly test water quality
Lake and pond owners and municipality leaders often wait until after a toxic algae bloom appears to conduct water quality tests, but a proactive testing program can help identify water quality impairments related to dissolved oxygen, pH or nutrient levels before they get out of hand. Over time, water quality data can be used to predict the onset of a bloom and prevent its impact without closing the waterbody or interfering with irrigation or drinking water services.
By taking the appropriate proactive steps to protect your lake or pond from HABs and nuisance algae, you can help ensure the protection of native plants and wildlife and the enjoyment of your waterbody throughout the summer. Through this approach, the ecological balance and natural beauty of your waterbody can be achieved, maximized and appreciated for years to come.

Commercial fishermen asked state regulators Tuesday night to make recreational fishermen tag their striped bass the way commercial operators do, to make sure they’re not taking too many fish.
But the idea died when Doug Jenkins, president of the Twin Rivers Watermen’s group, in Warsaw, outlined his proposal to the Virginia Marine Resources Commission’s finfish management advisory committee.
“We’re losing our rockfish (striped bass) quota and losing our crab industry,” Jenkins told the committee.
He said the 20 percent cut in striped bass quotas imposed three years ago have hit commercial fishermen hard.
They believe they’re being discriminated against and that there’s a need to be sure recreational fishermen aren’t catching too many striped bass.
Jenkins said there are enough striped bass to allow commercial fishermen to catch more, and that striped bass preying on crabs is one reason why crab populations are down.
But the request comes at a bad time, when nobody seems to know for certain what the real state of the striped bass stock is, said Jeff Deem, chairman of the advisory committee.
A new assessment of fish populations, based on more detailed studies of where and how fish are caught, could upend everything fisheries regulators think they know about striped bass, said VMRC chief of fisheries management Rob O’Reilly.
On top of that, he said, the Atlantic States Marine Fisheries Commission last year rebuffed the Virginia commission’s request for a 10-percent increase in the quota for striped bass.
“Ten percent, that’s all we were asking for and they voted it down,” he said.
“We get outvoted on striped bass all the time.”
In 2014, the Atlantic States fisheries commission cut Virginia’s quota by 24 percent, to 1.06 million pounds.
At the time, the state eliminated a quota for recreational fishermen, relying on daily catch limits to ensure they’re not taking too many striped bass. Jenkins saw the tagging proposal — which basically would mean fishermen could get a summons if a marine police officer found them with an untagged fish — as a way of enforcing limits on the recreational catch. That would make things fairer for commercial operators, he said.
“We don’t want to catch all the fish, we want to leave some for next year, just like you do,” Jenkins said.
Both the commercial and recreational catch are down from peaks hit last decade, the 2017 Atlantic States Marine Fisheries Commission review of its striped bass fishery management plan shows.
Commercial fishermen caught about 129,500 striped bass in 2016, while recreational fishermen landed 110,500.
But the drop in recreational landings was far steeper — a 69 percent drop over the decade. The decline in numbers caught by commercial operators was 8 percent, as the average weight of fish landed declined.
The Chesapeake Bay is the main place striped bass from up and down the Atlantic go to spawn. The Chesapeake Bay Program says the relative abundance of juvenile striped bass is on the rise, including in the James, York and Rappahannock rivers.
The fishery nearly collapsed in the early 1980s, but it has come back to become one of the most lucrative in the state, though at levels far below peaks of the late 1990s and early 2000s.
Southwest Florida Water Management District
Governor Rick Scott met with White House Office of Management and Budget Director Mick Mulvaney to continue advocating for full funding for the repairs to the Herbert Hoover Dike surrounding Lake Okeechobee. The Governor also spoke about the importance of the federal government quickly approving the EAA reservoir project, which will hold more water south of Lake Okeechobee. For decades, Congress has failed to address these issues and Governor Scott has fought for these projects which will ultimately help minimize harmful water releases to the St. Lucie and Caloosahatchee Rivers and Estuaries that can cause algae to bloom.
To immediately help the growing issues related to algal blooms, Governor Scott announced that at his direction, the Florida Department of Environmental Protection (DEP) has partnered with the South Florida Water Management District (SFWMD) to identify additional funding for more water flow monitoring stations along the Caloosahatchee River. These devices will provide water managers with new data to assess conditions in the river and the origin of water following into the system. This will help water mangers determine the best course of action to help our communities.
Governor Scott said, “Today, I met with the White House on the importance of quickly providing full funding for the repairs to the Herbert Hoover Dike and approving the EAA Reservoir project. Our focus remains on limiting the harmful impacts from Lake Okeechobee water releases by the federal government, and after decades of Congressional inaction, our communities are facing this problem once again. The state continues to take proactive and unprecedented steps to help solve this problem because our families deserve action and clean water.”
DEP Secretary Noah Valenstein said, “The health of Florida’s coastal estuaries and the waterways that feed them are vital to our state’s environment, economy and communities. DEP continues to actively monitor our waterways and these additional stations will help us and our local partners respond to changing conditions. DEP remains committed to partnering with our local communities to better protect our waterways.”
SFWMD Governing Board Member Jaime Weisinger said, “Additional monitoring means better information for making informed decisions. These monitoring stations will help provide new flow data to DEP and further aid in the state’s mission restore and protect the Caloosahatchee Estuary.”
Mayor of Sanibel Kevin Ruane, said “The City of Sanibel and our west coast partners are very pleased that the DEP is moving forward with installation of flow monitoring devices within the Caloosahatchee watershed. On average, more than 50 percent of the flow that the Caloosahatchee estuary receives comes from the watershed. The information provided by the flow monitoring devices will help resource managers identify where stormwater runoff is coming from and determine the types of projects and best management practices needed to address these flows in the future.”
In addition to the water flow monitoring stations, three additional monitoring stations are being installed through a joint agreement that was approved by the Lee County Board of County Commissioners last week to expand water monitoring efforts in the downstream Caloosahatchee watershed. These monitoring stations will be located below the Franklin Lock along the freshwater tributaries of the Caloosahatchee Estuary. Funding for this project is being provided by DEP, SFWMD, U.S. Geological Survey and Lee County. Coastal communities in Florida are already seeing the impacts and algae blooms due to lake releases this year. Last year, the Governor signed legislation to expedite the EAA Reservoir and secured an additional $50 million for the Herbert Hoover Dike, bringing the state’s total investment to $100 million.
Also, last week, Governor Scott directed DEP to issue an Emergency Order urging the U.S. Army Corps of Engineers and SFWMD to take emergency actions to help redirect the flow of water out of Lake Okeechobee south.
