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. It is speculated that the year class strengths are as follows: 1998>1997>1996. gccst Fisheries resources gccst Salt water fish gccst Fishing area gccst Fisheries management Rose, George A., 1948- Canada.
