Description

In the first week of June 1998-2000, female snow crabs were collected from exploited populations in Disko Bay and the area around Sisimiut, to study the reproductive condition of mature females. Analyses of ovaries and broods were performed on the females. Eggs hatched mainly in April and May and the fecundity was positively correlated with carapace width at both locations. Based on the development of ovaries and brood, females seem to have a 2-year reproductive cycle in the colder area around Sisimiut and a 1-year reproductive cycle in Disko Bay where bottom temperature is warmer.
