Innovative Coral Restoration Begins in Hawaiʻi After Ship Grounding

3/14/2025 - By fisheries.noaa.gov. A promising and emerging coral restoration technique is being tested in the coastal waters of Hawai‘i for the first time. Scientists are testing rubble stabilization as a coral restoration technique in the coastal waters of Hawai‘i for the first time, with promising results. It involves securing loose, broken… SEE MORE

Genetic Diversity in Alaska Red King Crab May Provide Resilience to Climate Change

1/10/2025 - By noaa.gov. New genetic research on the Alaska red king crab reveals previously undiscovered diversity among different regions, suggesting the species is more resilient to climate change and changing ocean conditions. Maintaining genetic diversity within and among populations is vital to ensure species are resilient to challenging conditions. Without it,… SEE MORE

Where Do Atlantic Salmon Go to Beat the Heat?

11/25/2024 - By fisheries.noaa.gov. As a key river habitat warms, researchers race to protect cold water patches critical to salmon survival. Researchers have successfully used cameras operated from a helicopter to map surface water temperatures in Maine’s Narraguagus River. This is an important step toward habitat conservation for endangered Atlantic salmon and… SEE MORE
Wetlands provide a buffer from wave energy for shorelines and communities behind them. But sea level rise, storms, and other challenges are causing wetlands to erode. We’re working to restore these important habitats. Photo: Chesapeake Bay Program/Will Parson.

Protecting and Restoring Habitat in Virginia’s Middle Peninsula

11/19/2024 - By fisheries.noaa.gov. Healthy wetlands and oyster reefs support fish, wildlife, and communities. Virginia’s Middle Peninsula is a beautiful part of the Chesapeake Bay watershed—both on and off the water. But it faces challenges due to climate change, a lack of capacity to restore habitat, and rural coastal economic hardship. While the Middle… SEE MORE

Surprise! Japanese Sardines Astonish Scientists by Crossing the Pacific to the West Coast

11/18/2024 - By fisheries.noaa.gov. Next generation genomic sequencing of Pacific sardine reveals not one, but two species of sardine in the California Current in 2022 and 2023. When research scientist Gary Longo first saw the results of his genomic analysis of sardines, he thought he must have mixed up his samples. Besides… SEE MORE
