Growth per molt of male snow crab Chionoecetes opilio from Conception and Bonavista Bays, Newfoundland
Abstract: Over 6000 male snow crabs were tagged during a 6-year period in Conception Bay ... , Newfoundland, in order to estimate the increase in size at the time of molting. Ninety-two animals were ... that 20 of these had molted once while the remainder molted twice. Two lines of evidence support ... this interpretation.
