Dogfish research reveals migration surprises

SOUTH KINGSTON, RI – It’s been a long-held belief that spiny dogfish migrate south for the winter and return to New England each spring, so much so that the federal dogfish fishery management plan has long allocated quota based on seasons.

However, two recent research studies funded by the Kingston-based Commercial Fisheries Research Foundation (CFRF) provide evidence that most spiny dogfish do not mass migrate. In fact, only a small percentage of dogfish do.



Dogfish can adapt to even very warm waters while other fish cannot, tolerating a very broad range of temperatures, from 32° F to 80° F.
