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 ... long as those presumed to have molted once. Second, a regression line fitted to data on single-molters ... predicted the size after two molts in close agreement with a regression line fitted to data on double ... -molters.
