Determination of the area prospected by a baited trap from a tagging and recapture experiment with snow crabs (Chionoecetes opilio
The area of influence of a baited trap of the type used in the southwestern Gulf of St. Lawrence snow crab fishery was studied by releasi ng tagged crabs at increasing distances from the bait and noting recaptures after fishing periods of 24 and 48 hr. For the shorter fishing period, the recapture r...
