Abstract
This document summarizes biological information on nine groundfish species and bluefin tuna in the southern Gulf of St. Lawrence. This is part of background information being provided in order to determine potential effects that may result from the development of oil and gas in an area of the southern Gulf. The species reviewed are Atlantic cod, white hake, American plaice, witch flounder, winter flounder, yellowtail flounder, Greenland halibut, redfish, Atlantic halibut and bluefin tuna. For each species, a review is made of literature on distribution, seasonal movements, stock composition, spawning, early life stages, and feeding.
