Celebrating Oysters During Oyster Week

10/21/2026

By fisheries.noaa.gov, fisheries.noaa.gov. Oysters are great multitaskers! They provide many benefits to the ecosystem they live in. They are filter feeders—they clean the water as they eat. And they grow in reefs, which provide great habitat for many other species. But in many places, their population has plummeted. So we… SEE MORE

Marine Heatwave Triggered a Hybrid Crab Surge in the Bering Sea

10/21/2026

By fisheries.noaa.gov, fisheries.noaa.gov. A team of scientists at the Alaska Fisheries Science Center’s Kodiak Laboratory has uncovered an unexpected ecological aftermath following the major 2018–2019 Bering Sea marine heatwave. The results, published in a new Proceedings of the National Academy of Sciences study, show the abundance of snow-Tanner crab hybrids increased by more… SEE MORE

Highly Migratory Species Management: Managing Shared Resources at Home and Around the World

10/16/2026

By fisheries.noaa.gov, fisheries.noaa.gov. Highly migratory species—like Atlantic yellowfin tuna, Pacific albacore, and Atlantic swordfish—travel thousands of miles across state, national, and international boundaries throughout their lives. These important commercial and recreational fisheries support seafood businesses and coastal communities across the United States. But highly migratory fish don’t recognize state or national borders, so… SEE MORE

Large-scale Marine Debris: 4 Ways to Clean up the Big Stuff

10/12/2026

By fisheries.noaa.gov, fisheries.noaa.gov. Marine debris is a challenging problem. Across the country, NOAA and partners remove everything from lost fishing gear tangled on the seafloor to sunken vessels, abandoned tire reefs, and other trash that have become hazards to navigation and marine ecosystems in the ocean and Great Lakes. Beginning in… SEE MORE

Kelvin Waves, Explained

10/11/2026

By fisheries.noaa.gov, fisheries.noaa.gov. You may be hearing a lot about Kelvin waves in the news. What are Kelvin waves, and how are they related to El Niño? We asked oceanographer Michael Jacox, from the Southwest Fisheries Science Center and NOAA Physical Sciences Laboratory, to explain the phenomenon. What is a Kelvin wave and… SEE MORE

How Will El Niño Affect Your Local Fisheries?

10/10/2026

By fisheries.noaa.gov, fisheries.noaa.gov. What does El Niño mean for U.S. fisheries and marine life? What can fishermen and coastal communities expect to observe and experience as this event continues and potentially intensifies? And what are scientists at NOAA Fisheries doing to track this natural phenomenon? The El Niño-Southern Oscillation is a powerful… SEE MORE

Kelp Farms and Marine Life Co-Exist in Southeast Alaska

10/3/2026

By fisheries.noaa.gov, fisheries.noaa.gov. Marine aquaculture, or mariculture, provides economic opportunities for coastal communities in Alaska through farming shellfish and seaweed. NOAA Fisheries continues to support Alaska’s growing aquaculture industry through policy and permitting—providing access to resources and research. A recent study highlights one of our newest aquaculture research collaborations. Through this… SEE MORE

Seeing Double: Good News for Rare False Killer Whales in Hawaiʻi

9/24/2026

By fisheries.noaa.gov, fisheries.noaa.gov. Research partners spotted two endangered main Hawaiian Islands insular false killer whale calves this year, and they’re starting to grow up! This is a rare and exciting discovery for this small, resident population of only about 140 individuals Range of the endangered main Hawaiian Islands insular false… SEE MORE

2026 Pacific Coral Surveys Complete

9/23/2026

By fisheries.noaa.gov, fisheries.noaa.gov. NOAA scientists returned from American Samoa and the Pacific Islands Heritage Marine National Monument after conducting coral reef monitoring surveys. The team sailed south from Honolulu to Jarvis Island, Palmyra Atoll, and Kingman Reef, where they completed their suite of surveys. After a 2,000 kilometer transit down… SEE MORE

Managing Genetic Risk in Offshore Aquaculture

9/19/2026

By fisheries.noaa.gov, fisheries.noaa.gov. Aquaculture can sustainably produce seafood to complement wild-caught fisheries. However, like all food systems, aquaculture requires sound science to ensure farmed species don’t harm wild species. Scientists at NOAA’s Southwest Fisheries Science Center are working to understand the genetic risks in offshore aquaculture. NOAA has identified 21,000… SEE MORE
