November 5, 2026 — A NOAA Fisheries analysis shows increased depredation by sharks in the Gulf of Mexico and the Southeast Atlantic.
The analysis looked at data from the Southeast Fisheries Science Center’s Bottom Longline Survey, which focuses on sharks, red snapper, yellowedge and red grouper, and golden tilefish from Brownsville, Texas, to Cape Hatteras, North Carolina.
October 20, 2026 — Depredation, the removal of or damage to hooked fish or gear by sharks or other marine predators, is a growing concern among fishing communities. Depredation results in increased mortality for managed fish stocks, economic loss, and degraded fishing experiences.
NOAA Fisheries biologists Dr. William “Trey” Driggers and Dr. Walter Ingram recently analyzed data from the Southeast Fisheries Science Center’s Bottom Longline Survey. Their goal: to determine trends in depredation rates over the past two decades. This is one of the first fishery-independent analyses of shark depredation—most research has been conducted in the fishery. The data confirm what anglers are seeing on the water: increasing trends in depredation by species like sandbar, blacktip, bull, and tiger sharks.
The annual Bottom Longline Survey, which started in 1995, samples U.S. waters of the Atlantic Ocean, including the Gulf of America, from Brownsville, Texas, to Cape Hatteras, North Carolina. Scientists use these data to monitor trends in abundance of federally managed sharks and other fish species like red snapper. It provides fishery-independent indices of abundance for numerous federal stock assessments in the Southeast region. When the survey protocol was standardized in 2001, Dr. Driggers recognized the importance of collecting data on depredation events. He added it as a standard data collection metric for the survey.
Since 2005, the survey has collected data on:
This has resulted in a standardized record of depredation events for all survey longline sets for more than two decades.
August 17, 2026 — Federal fisheries officials heard a familiar complaint from Guam fishers this month: Sharks are stealing their catch, the fixes on the market don’t work, and the island still has no clear path to federal disaster money when storms wipe out their gear.
The Western Pacific Regional Fishery Management Council and the Pacific Islands Fisheries Group hosted a community meeting last week at the Guam Museum Art Cafe, part of a series of gatherings the groups have held across the region to collect input on federal fisheries policy. The Council’s Guam Advisory Panel followed with its own meeting Aug. 8 at the Council office in Hagåtña, taking up commercial fishing rules inside the Marianas Trench Marine National Monument and 2026 strategic planning.
Last week’s gathering was one of close to 40 meetings the fisheries group has held across the Pacific over the past year and a half, part of an ongoing effort to document fisher concerns for the Council and its federal partners. Those observations feed into the Council’s annual Stock Assessment and Fishery Evaluation reports, which Jesse Rosario, the Council’s representative in Guam told The Guam Daily Post help shape recommendations on adapting fishery management to a changing climate. The Council is also building an online and mobile app that will let fishers report shifts in fish abundance, currents and weather directly, with a launch targeted for later this year.
Shark depredation, when sharks strip fish off the line before a catch reaches the boat, ranks among the most pressing issues raised by Guam’s small-boat fishers. According to Rosario, the Council held an international workshop on the problem in February that paired fishers with technology developers and scientists working on deterrent devices.
One Guam fisher put a magnetic deterrent that cost him nearly $70 to the test over two days on the water and came away unconvinced. He described attaching the device near the hook, expecting it to disrupt a shark’s electrical receptors before it reached the bait.
