摘要

In Atlantic Canada, the snow crab, commercial fishery began in the mid-1960's in the southern Gulf of St. Lawrence and rapidly expanded to cover fishing grounds in the northern Gulf of St. Lawrence and Atlantic shore from southern Nova Scotia to Labrador. These fishing areas are currently divided into 61 management zones with total landings at approximately 93 000 tons in 2008. This is a male only trap fishery with a minimum size limit of 95 mm carapace width. The historical fluctuation of landings and/or biomass estimates in certain fisheries in eastern Canada showed a cyclic-like pattern with a 4-6 year ascending period followed by a 4-6 year descending period. Eastern Canada's snow crab fisheries are deemed to be fully exploited. The biological knowledge of the species has rapidly progressed since the finding of a terminal molt in male snow crab in 1986. Since then, numerous studies have been conducted on a wide range of subjects. In this review, the development of snow crab fishery and the life history of snow crab in eastern Canada are described and the perspective of the eastern Canadian snow crab stocks is discussed.
