摘要：

An analysis of results obtained during the winter groundfish surveys in the Gulf of St Lawrence since 1978 was undertaken by relating the Gadus morhua catch to the distance from ice edge while taking temperature and depth variables into account. A strong thermal gradient close to the bottom would increase the concentration of cod and thus its catchability. -from Author
