Louisiana to help pay for devices that can save sea turtles from shrimp nets

October 21, 2020 — Louisiana is starting a financial assistance program to help shrimpers buy new gear to make their nets less lethal for endangered sea turtles.

The new $250,000 state program will reimburse up to 60% of the cost for special metal grates known as TEDs, or turtle excluder devices, for shrimping nets used in the Gulf of Mexico. TEDs create an opening that allows trapped turtles to escape nets before they drown.

Starting in April, a federal law will expand TED requirements to include skimmer vessels that are 40 feet long and longer. About 1,500 TEDs will need to be purchased for 400 boats in Louisiana, according to the state Department of Wildlife and Fisheries, which will oversee the Skimmer Turtle Excluder Device Reimbursement Program.

Louisiana helps inshore shrimpers buy turtle escape hatches

October 14, 2020 — Louisiana will help inshore shrimpers buy turtle escape hatches that will be required next year for some boats in the Gulf of Mexico and southeastern Atlantic, Gov. John Bel Edwards said Tuesday.

The $250,000 program will pay up to 60% of the cost for two of the grates called “turtle excluder devices,” or TEDs, a news release said. Some of the money comes from BP payments to restore the Gulf after the oil spill in 2010.

Big offshore shrimp trawlers have had to use such devices since late 1989. Protests against that rule included shrimp-boat blockades of Texas and Louisiana ship channels.

Atlantic scallop fishers object to ongoing sea turtle litigation

October 7, 2020 — Atlantic scallop fishermen in the Northeast U.S. are objecting to the latest ruling in a long string of litigation regarding the fishery’s responsibility to protect endangered sea turtle species.

A recent court ruling determined that the National Marine Fisheries Service (NFMS) needs to revise the method it uses for its incidental take statements. The scallop fishery, however, asserts that it has already taken steps to protect sea turtles, and that the litigation is unnecessary.

Federal court ruling requires NMFS to improve sea turtle monitoring in Atlantic scallop fishery

October 6, 2020 — A federal court has ruled in favor of an Oceana challenge to National Marine Fisheries Service (NMFS) rules regarding the incidental take of endangered sea turtles in the U.S. Atlantic scallop fishery, siding with the nonprofit in its assertion that the rules are inadequate.

The ruling, according to Oceana, is the latest in a “decades-long effort” by the nonprofit to ensure the scallop fishery “minimizes its harmful impacts on sea turtles.” The ruling will require the NMFS to revise its incidental take statement (ITS) to either more thoroughly explain the surrogate information, or revise its selections.

Loggerhead Turtles Record a Passing Hurricane

September 1, 2020 — The following was released by NOAA Fisheries:

In early June 2011, NOAA Fisheries researchers and colleagues placed satellite tags on 26 loggerhead sea turtles in the Mid-Atlantic Bight. The tagging was part of ongoing studies of loggerhead movements and behavior. The Mid-Atlantic Bight, off the U.S. East Coast, is the coastal region from Cape Hatteras, North Carolina to southern Massachusetts. A little more than 2 months later, on August 28, Hurricane Irene passed through the area, putting 18 of the tagged turtles in its direct path. The researchers were able to track changes in the turtles’ behavior coinciding with the hurricane, and found that they reacted in various ways.

“Hurricanes are some of the most intense weather events loggerheads in the mid-Atlantic experience, and we thought it was worth investigating how turtles in our dataset may be influenced by these dramatic environmental changes,” said Leah Crowe, a contract field biologist at the NOAA Northeast Fisheries Science Center’s laboratory in Woods Hole, Massachusetts, and lead author of the study published recently in Movement Ecology. “It was a perfect storm situation in terms of location, timing, and oceanographic conditions. We found that the turtles responded to the changes in their habitat in different ways.”

Satellite tags attached to a turtle’s carapace, or shell, transmitted the turtles’ location and dive behavior. They also recorded sea-surface temperatures and temperature-depth profiles for approximately 13 months. This enabled the researchers to investigate the movements of 18 juvenile and adult-sized loggerhead turtles and associated oceanographic conditions as the hurricane moved through the region.

Most of the turtles moved northward during the hurricane, aligning themselves with the surface currents — perhaps to conserve energy. Researchers observed longer dive durations after the hurricane for turtles that stayed in their pre-storm foraging areas. Some dives lasted an hour or more, compared with less than 30 minutes for a typical dive before the storm.

The turtles that left their foraging areas after the hurricane passed moved south earlier than would be expected, based on their normal seasonal movements. This change was also more than a month earlier than the typical seasonal cooling in the water column, which is also when the foraging season for loggerhead turtles ends in the Mid-Atlantic Bight.

“Loggerheads experience environmental changes in the entire water column from the surface to the bottom, including during extreme weather events,” said Crowe. “This study was an opportunistic look at turtle behavior during a hurricane. Their behavior makes loggerheads good observers of oceanographic conditions where they forage.”

Habitats for endangered green sea turtles will be federally protected in Florida

August 25, 2020 — Endangered green sea turtles will have some of their nesting beaches in Florida protected by federal agencies under a new legal agreement with conservation groups.

The U.S. Fish and Wildlife Service and National Marine Fisheries Service must designate protected critical habitats for green sea turtles by June 30, 2023, the Center for Biological Diversity said in a statement this week.

The agencies will likely consider proposing protections for beaches where green turtles nest in Florida, Georgia, North Carolina and South Carolina, as well as offshore oceanic habitat in the Southeast and on the West Coast, according to the agreement. These critical habitats designations don’t prohibit development, but they require that any project that’s permitted by a federal agency must minimize harm to these special areas.

“We’re thrilled that these imperiled creatures will finally get the habitat protections required by the Endangered Species Act,” said Jaclyn Lopez, Florida director at the Center for Biological Diversity. “Green sea turtle recovery has come a long way, but the fight’s not over yet.”

California Takes Step to Protect Leatherback Sea Turtles

August 20, 2020 — California took a step Wednesday toward placing Pacific leatherback sea turtles under state protection as the species faces potential extinction from human-caused problems.

The state Fish and Game Commission voted 5-0 for the species to become a candidate for threatened or endangered status under California’s Endangered Species Act.

That triggers a year-long review before the commission makes a final decision. The turtle will receive state protection during that time.

Conservation groups applauded the move.

“Leatherbacks have traveled across the Pacific for millions of years. California has now committed to ensuring they survive reckless fishing practices and other threats to their existence,” said Catherine Kilduff, an attorney for the Center for Biological Diversity, which petitioned for the action along with the Turtle Island Restoration Network.

Feds: NW Atlantic Leatherback Turtle Population Listing Change Not Warranted; Species Still at Risk

August 13, 2020 — A new review of leatherback sea turtle science found that seven distinct populations of leatherback sea turtles face a high extinction risk, according to the National Marine Fisheries Service and U.S. Fish and Wildlife Service.

The federal agencies released the information Monday, noting that all seven are currently listed as endangered. Neither agency proposed a change to current global listings since a petition to identify the Northwest Atlantic population as a distinct population segment and threatened, not endangered, under the Endangered Species Act was unjustified.

Species may swim thousands of kilometers to escape ocean heat waves

August 11, 2020 — When an intense heat wave strikes a patch of ocean, overheated marine animals may have to swim thousands of kilometers to find cooler waters, researchers report August 5 in Nature.

Such displacement, whether among fish, whales or turtles, can hinder both conservation efforts and fishery operations. “To properly manage those species, we need to understand where they are,” says Michael Jacox, a physical oceanographer with the National Oceanographic and Atmospheric Administration based in Monterey, Calif.

Marine heat waves — defined as at least five consecutive days of unusually hot water for a given patch of ocean — have become increasingly common over the past century (SN: 4/10/18). Climate change has amped up the intensity of some of the most famous marine heat waves of recent years, such as the Pacific Ocean Blob from 2015 to 2016 and scorching waters in the Tasman Sea in 2017 (SN: 12/14/17; SN: 12/11/18).

“We know that these marine heat waves are having lots of effects on the ecosystem,” Jacox says. For example, researchers have documented how the sweltering waters can bleach corals and wreak havoc on kelp forests. But the impacts on mobile species such as fish are only beginning to be studied (SN: 1/15/20).
