Overfishing linked to rapid evolution of codfish

The overfishing of codfish spanning the second half of the 20th century indicates that human action can force evolutionary changes more quickly than widely believed, according to a Rutgers-led study.

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. ...
