| 520 | 0 |a"Cod being an important predator of juvenile snow crabs, it was hypothesized that the recruitment of crabs to the fishery is negatively dependent on previous abundance of cod. An exponential equation was fitted by regression to various average cod (4TVn) biomass and crab catches, from the southwestern Gulf of St. Lawrence, using an initial lag time of 6 years (approx. age of recruiting crabs). The strongest relation (r 2 = 0.91) was found when snow crab catch in a given year was correlated with the average biomass of cod present 3 to 6 years before. Cod appears to be a major controlling factor of snow crab recruitment to the fishery and its steady increase in abundance since 1976 could suggest a possible reduction in the catches of snow crab from the southwestern Gulf in a near future."--Abstract. |
