Cod behave differently in noisy environments

Underwater noise from seismic surveys affects the behavior of Atlantic cod. These are the results of research by Leiden biologists in collaboration with colleagues from Belgium. During such surveys the fish are less active ...

Spiny dogfish eat Atlantic cod: DNA may provide some answers

Conventional observations show that spiny dogfish in the western North Atlantic rarely eat Atlantic cod. However, some believe the rebuilding dogfish populations are limiting depleted cod numbers by competition or predation. ...

Oceanographers produce first-ever images of entire cod shoals

For the most part, the mature Atlantic cod is a solitary creature that spends most of its time far below the ocean's surface, grazing on bony fish, squid, crab, shrimp, and lobster—unless it's spawning season, when the ...

Adult fish 'predict' availability of food for their young

In seasonal environments, timing is everything: Ecosystem dynamics are controlled by how well predators can match their prey in space and time. A recently published study, led by University of Hawai'i at Mānoa oceanographer ...
