Sanctuary’s Open and Closed Fishing Areas Compared to Test Policy Effectiveness

Scientists from the National Centers for Coastal Ocean Science are comparing several areas of Gray’s Reef National Marine Sanctuary to help Sanctuary officials differentiate changes to fish populations due to natural events, or whether the changes derive from human activities. The multi-agency research cruise runs from May 27 – June 9, 2012. The researchers gather data […]

Rise in Asian Tiger Shrimp sightings prompts scientific look at invasion concerns | NOAA Press Release

The recent rise in sightings of non-native Asian tiger shrimp off the U.S. Atlantic and Gulf of Mexico coasts has government scientists working to determine the cause of the increase and the possible consequences for native fish and seafood in those waters. Researchers from the U.S. Geological Survey and National Oceanic and Atmospheric Administration are […]

Partnerships: Bringing Scientists and Resource Managers Together to Explore Opportunities for Using Fisheries Acoustics in the Southeast US

Underwater acoustics for mapping the water column Underwater acoustics (ie. fisheries sonars) uses sound to detect and map the presence of fish and other organisms in the water column.  An acoustic signal or ping is sent into the water column from an transducer.  The strength of the return signal is measured and is correlated to […]

Hard Clam Populations May Decrease Due to Stone Crab Range Shifts

NCCOS-funded research into the ecosystem effects of climate change may improve management of the commercially important shellfish populations in a warming climate. Stone crabs (Menippe mercenaria), normally found only in South Atlantic estuaries, are moving northward into the mid-Atlantic due to warming temperatures. This pole-ward range shift is predicted to increase interactions between stone crabs […]

Algal Bloom Toxin Neutralizer Tested in Real-World Conditions

Taking advantage of a toxic red tide blooming off of the Florida coast, two NOAA-funded scientists are validating a natural method that neutralizes the algal toxin. Shellfish throughout the Gulf states are susceptible to contamination by red tide algae (Karenia brevis), and commercial operators lose money when their beds are closed for extended periods. Applying […]

Making Waves: Powerful Fish-Killing Toxin May Lead to Human Health Benefits (Episode 36)

In 2002, a mysterious disease began killing fish at a commercial aquaculture facility in North Carolina. Lots of fish. Over 21,000 striped bass died during the outbreak. At the time, no one knew what caused this massive fish kill. Why did it happen? Would it happen again? We now know that the culprit behind the […]

Northward Creep of Tropical Disease Another Consequence of Climate Change?

Scientists from the National Centers for Coastal Ocean Science, working with NOAA Fisheries Marine Mammal Health and Stranding Response researchers, identified multiple cases of lobomycosis in stranded and live, free-swimming bottlenose dolphins from coastal North Carolina. Lobomycosis is a chronic fungal infection of the skin and, until now, only been reported in people and dolphins […]
