Nursery-Raised Coral Spawning to Build Reef Habitat in Keys

In August, researchers at the Florida Fish and Wildlife Conservation Commission (FWC) observed transplanted nursery-raised staghorn coral (Acropora cervicornis) spawning for the first time at Tropical Rocks, about 4 miles offshore of Marathon.

These corals were supplied by the Coral Restoration Foundation and Mote Marine Lab nurseries and outplanted by FWC. The project was made possible by the American Recovery and Reinvestment Act via The Nature Conservancy.

The FWC and the Conservancy are reseeding coral reefs in efforts to aid recovery of wild staghorn populations, which contributes significantly to reef growth, island formation, and coastal protection, while providing essential habitat for a number of important reef fish.

“This is the first time that we have seen staghorn coral spawning at the reef tract that included corals grown as part of our nursery program,” said Caitlin Lustic, coral recovery coordinator for the Conservancy in Florida.

“This spawning event shows that outplanted corals have the ability to reproduce just like a natural colony and furthers our goal of creating breeding colonies of coral that can repopulate reefs on their own.”

The FWC, in collaboration with the Conservancy and other American Recovery and Reinvestment Act partners, began construction on the Middle Keys coral nursery in late 2009 but suffered setbacks due to a coldwater kill and, later, a warm-water bleaching event. The goal of the American Recovery and Reinvestment Act project was to expand the current nurseries, develop new nurseries and outplant high numbers of nursery-grown corals throughout the Florida reef tract and the U.S. Virgin Islands.

“With this project, we developed excellent working relationships with the Conservancy and the rest of our partners,” said Kerry Maxwell, coral researcher with the FWC.

“Together we boosted threatened staghorn populations and realized the ultimate goal of the project: spawning. Even though the project backed by the American Recovery and Reinvestment Act is complete, I anticipate we will all continue to collaborate toward the common goal of coral reef restoration.”

Vote to Help Fund Bass Conservation Programs

 

Cast your votes daily through Oct. 13 to help bass conservation --- and B.A.S.S. Conservation --- at Nationwide Insurance. The winning organization will receive $45,000.

B.A.S.S. has more members than the two leading organizations combined, and certainly more people fish than hunt elk and turkey.

“Are we not as passionate about conservation and what it means to our sport?” asks Gene Gilliland, national conservation director for B.A.S.S.

I know that I am. I hope that you are as well.

To vote, click on the B.A.S.S. Conservation logo and it will change from gray and white to color. You then will type in the two “secret” words to cast your vote. If you can’t read them (and I couldn’t) click on the speaker below and the words will be spoken for you.

You can vote once daily from each device (computer, cell phone, etc.) with internet access.

Future Bright for Trophy Bass in Florida, Texas

The best is yet to come for anglers who pursue big bass in Florida and Texas. Even though they have decidedly different approaches, each sponsors a program that optimizes opportunities provided by the Florida strain of largemouth.

Of course, it’s only logical that the two have differing strategies, since one manages for non-native fish in manmade impoundments, while the other focuses on native fish in natural lakes. As a consequence, Texas constantly researches methods for growing more and ever larger bass, while Florida has set up a system that both helps anglers find the state’s biggest fish and encourages catch-and-release.

Implemented just two years ago, the Sunshine State’s TrophyCatch still is in its “infancy stages,” according to Bill Pouder, a freshwater fisheries administrator for the Florida Fish and Wildlife Conservation Commission (FWC). It was borne out of the state’s Long-Term Black Bass Management Plan, with the intent of ensuring “Florida is the undisputed bass fishing capital of the world.”

Word of mouth, Pouder added, has helped considerably in motivating fishermen to report catches of 8 pounds and larger. “If I’m an angler who catches an 8-pound bass and all I have to do is provide a photo and measurements in exchange for $100 in gift cards and prizes, then I’d be very encouraged to do it,” he said.

Statistics certainly bear out that assessment, too. From Oct. 1, 2012, through September 2013, fishermen entered 206 fish in TrophyCatch. But 679 bass were logged in during the eight months that followed. Of those 885 fish, 244 weighed between 10 and 12.99 pounds and 5 weighed 13 pounds or more.

As possibly the biggest surprise of the program thus far, three of those latter fish, including the largest at 14-9, came from Kingsley Lake, a semi-private fishery in Clay County. That discovery goes to the heart of how TrophyCatch will enhance opportunities for Florida anglers to catch lunkers: It tells them where they are.

Not so surprising is that Lake Istokpoga tops the list of public waters, followed by Okeechobee, Toho, Kissimmee, and St. Johns River. But 235, or more than 25 percent, of those fish have been caught in small, unnamed waters, including private ponds, golf course ponds, retention ponds, and undisclosed public lakes.

“Those types of waters aren’t typically managed,” Pouder said. “But that suggests we might look into that for the future.”

Also worthy of note is that TrophyCatch has given lie to the notion that anglers must use shiners to catch big bass in Florida. More 60 percent of entries were caught on artificials.

More of that kind of helpful information will be available to anglers soon, as FWC develops a more in-depth website for TrophyCatch, which will allow each entrant to have his or her own page.

In Texas, meanwhile, managers continue to look for new ways to improve the state’s trophy bass fisheries through ShareLunker, a program built around stocking Florida strain largemouths. Before the Lonestar State introduced the larger variety of black bass, its state record of 13.5 remained unchallenged for 37 years. Since stocking began in the 1970s, the record has been broken six times, and three since ShareLunker began in 1986.

Current Texas record is 18.2, larger even than the biggest bass documented in Florida at 17.27.

Courtesy of ShareLunker, Florida bass now swim in 62 Texas impoundments. They are spawned in hatcheries from the ShareLunker entries of 13 pounds or more that Texas fishermen donate to the program.Incredibly, 51 percent of ShareLunker entries are pure Florida bass, with the rest being hybrids. Yet sampling reveals that Florida bass typically make up only about 7 percent of a fishery’s bass population.

“A real value of the program has been that it has convinced anglers that they do not have to kill their catch to get a trophy,” said Allen Forshage, director of the Texas Freshwater Fisheries Center.

In exchange for donating their fish, anglers are given replica mounts.

Right now, focus is on DNA and how tracking it might help produce a fish that could rival the world record of 22-4. While breeding ShareLunker entries to male ShareLunker offspring, biologists have developed a technique to identify both parents in future trophy bass.

Tagging already has revealed that sometimes entries are caught more than once. In fact, one was caught three times.

“I was a pessimist when we first started this program,” Forshage said. “We had no idea that one day we’d have 62 lakes producing these lunker fish.”

Scientists Propose Length-Based Records for Threatened Species

When I first saw the following headline, I feared that this was one more assault on sport fishing by the preservationist movement:

Scientists Want to End Traditional Trophy Fishing of Threatened Species

But that is not the case. In fact, what these researchers are proposing makes a lot of sense.

“The most common method of certifying the size of landed fish is based on mass. But weighing large fish typically requires anglers to transport them to an official land-based weigh station—a method that makes it unlikely that the fish will survive,” says an article at Sciencemag.org.

“In many cases, this means the loss of egg-bearing females, because the females are larger than males in many species. So by killing big fish, the authors note, trophy anglers often remove individuals that are capable of producing the most high-quality larvae and helping depleted populations recover.

“Shifting to length-based records could reduce such mortality, says the research team, led by researchers at the University of Miami’s Abess Center for Ecosystem Science and Policy. Anglers could use cameras or smart phones to validate catches and release record fish where possible.”

Additionally, scientists propose this for just 7 percent of the species on the list maintained by the International Game Fish Association. Those are the ones listed as either  vulnerable, endangered, or critically endangered by the International Union for Conservation of Nature Red List.

David Shiffman, the study’s lead author and a marine biologist studying shark biology and conservation at the University of Miami, says the analysis was inspired by recent hearings concerning a proposed ban on killing scalloped and great hammerhead sharks in Florida waters— two species listed as endangered on the IUCN Red List.

“Several anglers said they were opposed to protecting these species, one of which is so depleted that it just became the first species of shark protected by the U.S. Endangered Species Act, because it would stop them from going for IGFA world records,” he says.

Green Decoys Argues TRCP Is Not Credible Voice for Anglers, Hunters

Activist Angler stopped promoting the Theodore Roosevelt Conservation Partnership awhile back, as I became more and more troubled by its political and financial ties to left-leaning groups, foundations and politicians. You can read one of my posts related to that here.

Here’s the essence of the issue for me: While TRCP has “conservation” in its name and many conservation groups for its members, it seems more closely allied, especially financially, to preservationists, many of whom want to restrict where we can fish and impose tighter gun controls. Some of those backers also believe that manmade climate change is “settled science,” and, as a consequence, advocate for ever tighter and more burdensome environmental regulations that are not supported by science.

I’m not suggesting that TRCP doesn’t do some good on behalf of fish and wildlife habitat. I believe that it does, and many of its coalition members are champions for fishing and hunting. But I also suspect that TRCP is a compromised organization and, over time, morphing into a preservationist Trojan horse amidst the conservation community.

With that in mind, today I received a press release from Green Decoys, which says, “A review of TRCP’s most recent tax records finds that it receives 77 percent of its contributions from just 8 donors, many of which are San Francisco-based environmentalist foundations.”

Will Coggin, senior research analyst, adds, “TRCP provides Big Green and Big Labor with a convenient mask for their agendas: Sportsmen. TRCP is nothing more than a puppet with a camo hat, in the pay and in the pocket of radical and left-wing interests . . .

“Sportsmen and other grassroots members of these organizations should be worried that they are being used as pawns by environmentalists,” continues Coggin. “You can’t receive the majority of your contributions from a handful of elitist urbanites and claim to be a credible voice for backwoods hunters and anglers.”

Go here to read what Green Decoys has to say about TRCP:

Here’s an excerpt:

On the Sideline for the Second Amendment

TRCP claims to support the right to hunt and fish, and so it should be a vocal proponent of gun rights. But when pressed, TRCP couldn’t offer a stance. “[O]thers know far more than we do about the Second Amendment,” TRCP stated. Bizarrely, WyoFile reports that Whit Fosburgh, head of TRCP, “doesn’t view President Obama as a threat to gun rights.” TRCP’s non-stance is even stranger given that a portion of every sale of firearms and ammunition is earmarked for conservation programs.
