Prolonged government shutdown could spell trouble for coral reef in Gulf of Mexico

January 8, 2019 — As the days of the federal government shutdown increase, so, too, do the chances of an emergency happening on the coral reef system 100 miles off the coast of Galveston.

And if an oil spill or a major mortality event occur during the shutdown, those who work in the Flower Garden Banks National Marine Sanctuary office will be powerless to mitigate it.

“If some sort of emergency occurs … the staff will have limited capacity to respond and basically the response would occur by the Coast Guard,” said Adrienne Correa, a Rice University researcher who serves on the sanctuary’s advisory council. “But the staff have a different type of knowledge of the reef … the Coast Guard lacks the tools and place-based knowledge.”

The sanctuary is a network of federally protected coral reef systems in the Gulf of Mexico. And at a time when a quarter of coral reefs worldwide are considered damaged beyond repair, it’s home to some of the healthiest reefs in the region.

Scientists say it’s because of its location: 70 to 115 miles off shore and 55 to 160 feet deep.

But the sanctuary has had problems in the past: 2016 brought the worst bleaching year for the sanctuary in more than a decade when 2 percent of the reef, inexplicably, died.

Snapper season could get even longer in 2019

December 7, 2018 — After a decade of enduring ever shrinking opportunities to enjoy catching, keeping and eating red snapper caught from Gulf of Mexico waters under federal jurisdiction, Texas recreational anglers in 2018 welcomed a modest loosening of restrictions that had choked much of the life from what long has been the state’s most popular offshore fishing activity.

Those fishing for snapper from private boats saw the length of the federal-water snapper season almost double, to 82 days. It was their longest season since 2007.

More positive developments could be on the way for the coming year, including a possible increase in the annual quota of red snapper allowed to be taken from the Gulf, a possibly longer federal-water snapper season, and changes to the dates of the 2019 open season for anglers in private boats targeting snapper in federally controlled water.

For the first time in a decade, Texas offshore anglers in 2019 could see a federal water snapper season that opens on a date other than June 1, or splits the limited open-season days across the calendar instead of opening June 1 and running continuously for however many days fisheries managers estimate it will take to land the annual quota. And Texas anglers will have opportunity to play an important role in deciding when those 2019 open-season days will fall, Texas fisheries officials said.

Gulf of Mexico Oysters are in Trouble, but There’s Hope and a Plan

November 28, 2018 — Oysters in the Gulf of Mexico have seen better days.

Aside from the Deepwater Horizon explosion and oil spill in 2010 — which killed between 4 and 8.3 billion adult oysters, according to NOAA — changes in freshwater flow along the Gulf and sedimentation caused by more frequent storms have taken their toll on the Gulf’s oyster population.

But all hope is not lost. In fact, there’s even a plan, according to a report by environmental organization The Nature Conservancy (TNC).

Compared to historic levels, an estimated 85 percent of the Gulf’s oyster population has been lost, and the impact ranges further than the $100-million-per-year market they provide.

Oyster beds in the Gulf are vital in improving water quality, providing protection from shoreline erosion and serving as a habitat for fish and wildlife.

The impact of waves, boat wakes and storm surge on the Gulf’s shoreline is reduced by oyster reefs. Reefs are also unique in that they can continue to grow to keep up with or even outpace sea level rise, according to an entry in the journal Nature, something hard sea walls can’t do.

Additionally, a single oyster can filter 50 gallons of water in one day. In places like Galveston Bay, a 130-acre reef containing 10 oysters per square meter would be capable of filtering about 260 million gallons of water each day. In comparison, Houston’s 39 wastewater treatment plants combined to filter 252 million gallons per day in 2009, according to Texas Parks and Wildlife.

Gulf Coast Looks to Maintain, Restore Oysters

November 26, 2018 — The oyster dressing is safe this year.

Since the Deepwater Horizon spill in 2010, 4 billion to 8.3 billion subtidal oysters were estimated to be lost across the Gulf coast. Many states are struggling.

Louisiana is the only state producing at a level at or higher than before the spill, according to Seth Blitch, The Nature Conservancy’s Director of Coastal and Marine Conservation in Louisiana.

“Oysters Gulfwide are kind of in a bad spot, but Louisiana is actually sort of the bright spot in terms of commercial production of oysters. Louisiana produces more oysters than any other state in the country, which is good,” Blitch said.

TNC recently released a report on oyster restoration in the Gulf.

According to the report, there’s been about a 50 percent to 85 percent oyster loss throughout the Gulf when compared to historic levels.

The oyster industry pulls about $220 million to Texas, Louisiana, Mississippi, Alabama and Florida. The decrease could affect not only oyster harvesters but restaurants and industries that use the shell, such as using it to supplement chicken feed.

Hurricane Harvey Didn’t Stop These Fish From Mating

November 20, 2018 — Every summer, a symphony of grunts, croaks and roars echoes below the surface of the western Atlantic and the Gulf of Mexico to signal the launch of spotted seatrout spawning season.

Last year, the noisy process—which finds males vibrating their air bladders in hopes of attracting fertile females eager to mate—coincided with the onslaught of Hurricane Harvey, a category 4 storm that made landfall in Texas on August 25. And as JoAnna Klein reports for The New York Times, a series of recordings captured by microphones placed at popular spawning grounds across Aransas Bay reveals just how persistent the trout are in their pursuit of reproductive success: Not only did they spawn on the days preceding and following the storm, but also on the day the eye of the hurricane passed directly over their habitat.

“These fish are resilient and productive, even in the face of such a huge storm,” lead author Christopher Biggs, a marine ecologist from the University of Texas at Austin, says in a statement. “On land, it was complete destruction, but these fish didn’t seem disturbed.”

The researchers’ findings, published in Biology Letters earlier this month, emerged largely by chance. Biggs tells Eos’ Jenessa Duncombe that he and his colleagues initially set out to study the fish’s breeding patterns, including where and how they spawn. Trout reproduction is best observed via aural methods, as the waters these fish call home tend to be too murky for visual analysis, so the researchers set up 15 underwater recording stations between April and June 2017.

Restoration projects seek to fight “tragic” decline in Gulf of Mexico oyster population

November 19, 2018 — Last week, the Alabama Department of Conservation and Natural Resources officially moved to cancel the state’s wild oyster season, which would have run from November through April.

Exploratory dives at oyster harvesting grounds had revealed a continued steep decline in the number of oysters in the state’s waters. Last year’s season was curtailed after fishermen harvested just 136 110-pound sacks of oysters, down from 7,000 sacks in 2013, according to the Associated Press.

Scott Bannon, director of the Marine Resources Division of the Alabama Department of Conservation and Natural Resources, said the findings revealed the apparent collapse of the region’s oyster ecology.

“It’s tragic, to be honest,” Bannon told AL.com.

Numerous factors have dealt blows not just to Alabama’s oyster grounds, but those of the entire Gulf of Mexico. The Deepwater Horizon oil spill, hurricanes, disease, and changes in freshwater flows to Gulf rivers and streams have collectively damaged the fishery to the point where up to 85 percent of the gulf’s original oyster reefs no longer remain intact.

According to a new report by The Nature Conservancy, “Oyster Restoration in the Gulf of Mexico,” this dramatic decline has damaged the stability and productivity of the Gulf’s estuaries and harmed coastal economies.

Seth Blitch, the director of coastal and marine conservation in Louisiana for The Nature Conservancy, told SeafoodSource the oyster habitat and the oyster fishery “is not in a particularly good place right now,” which could spell bigger problems for the region.

“Oysters, to me, are a great proxy to a lot of things,” he said. “If oysters are doing well, that’s a good indication of good water quality and of the health entire near-shore estuarine system. When oysters start to fail, that’s good indication there are larger issues at play.”

Reef restoration projects aim to bolster Texas’ record-low oyster population

November 16, 2018 — With oyster populations in Texas at historic lows, The Nature Conservancy is launching two new reef restoration projects that look to appease commercial fishermen and environmentalists alike.

Using funds from the Deepwater Horizon oil spill settlement, the group plans to develop 110 acres of reef in Galveston Bay and Copano Bay, near Rockport. Half of each reef will be designated as a marine sanctuary where the molluscs — which have significant economic and environmental benefits — may grow. The other half will be open for commercial fishing.

Construction of the new reefs is expected to begin this winter, with harvestable portions ready as soon as 2021.

Laura Huffman, regional director of The Nature Conservancy in Texas, said these projects show a new approach to oyster reef restoration, with the compatibility of building harvestable reefs at the same time as growing a healthy habitat.

Recent studies say fish oil could boost your heart

November 16, 2018 — Heart disease is the leading killer in America, and San Antonio is no exception.

But as the Washington Post reports, two recent major studies point to the possibility that medications derived from fish oils could help protect people from heart attacks, strokes and other types of cardiovascular ailments. These are medications, not supplements.

The long-term studies involved two drugs derived from omega-3 fatty acids. Both studies found the drugs, if taken appropriately, made a significant difference for people with diabetes or heart disease.

Louisiana inside red snapper limit; Florida, Alabama go over

November 5, 2018 — If Chad Courville didn’t physically show how upset he is with recent catch data posted for each of the five Gulf states, his words certainly did during Thursday’s Louisiana Wildlife and Fisheries Commission monthly meeting in Baton Rouge.

Courville, one of the commission’s seven, took note of a report indicating Florida’s recreational fishermen caught 113.5 percent of its allowed red snapper catch during its 40-day season. Alabama’s report was 100.2 percent.

“The MRIP numbers are insane,” Courville said, mentioning the federal Marine Resources Information Program data showing Alabama might have taken as much as four million pounds of snapper and its state agency reported on pounds of red snapper during the recreational season.

Meanwhile, Louisiana, using its highly accredited and federally approved LA Creel system, showed its state anglers took 99.2 percent of its allowed 700,000-pound-plus red snapper allowed limit. Mississippi reported at 95.6 percent while Texas’ numbers are not final because the Lone Star State continues to hold its state waters open to red snapper catches.

After decades of rescuing stranded sea turtles, NOAA’s Galveston lab plans to scale back

October 22, 2018 — The sea turtle was almost dead, stranded at the high tide line on a Galveston beach.

It had a thick coating of algae growing on its outer shell. Its body was thin, its eyes sunken. It wasn’t moving.

A beachgoer spotted the creature earlier this month and called a hotline for reporting stranded sea turtles. As soon as the phone rang, the NOAA Fisheries laboratory in Galveston sprang into action.

An employee collected the 40-pound turtle from the beach and brought it back to the lab. It was a Kemp’s ridley turtle — a critically endangered species — and it didn’t look good.

“It was basically one step away from being comatose,” said Ben Higgins, who manages the sea turtle program at the Galveston lab. “At one point, the staff came and got me and said, ‘We think it might be dead.’”

But it wasn’t dead. The NOAA staff put the turtle in a van and drove it to Houston. By the next morning, the turtle was sprawled out on an exam table at the Houston Zoo, letting senior veterinarian Dr. Joe Flanagan prod at it with purple-gloved fingers. The turtle got X-rays, blood work and a full physical exam.

The diagnosis: Dehydration and a touch of pneumonia.

“We got it just in time,” Higgins said. “It was very close to leaving us.”

But with some squid in its system and a prescription for antibiotics, the turtle was taken back to Galveston to recover in NOAA’s lab.

It’ll spend the winter in the lab, getting food and medicine and a heated tank. And if all goes well, it will be released back into the Gulf of Mexico sometime after the winter, when it can survive in the wild again.
