Distribution of 0 and 1 group cod in nearshore waters of Placentia Bay (NAFO Subdivison 3Ps), 1997-1998

By Dave Robichaud and George A. Rose

Abstract

Predicting recruitment and understanding its variability are important problems in fishery science. In Placentia Bay, in 1997 and 1998, 0 and 1-group cod were surveyed in nearshore eelgrass habitats. The distribution and relative abundance was compared among sites and between years. The mean catch rate of 0-group cod was 0.8 and 3.7 fish per set in 1997 and 1998, respectively. The 5-fold increase in catch likely represents an increase in total biomass of 0-group cod in the nearshore environment. Catch of 1-group cod followed similar patterns to the 0-group cod catch. Given catch magnitudes for 0 and 1-group cod in 1997 and 1998, we speculate that the year class strengths are as follows: 1998 > 1997 > 1996.
