| Summary: | No abstracts are to be cited without prior reference to the author.Distributions and abundances of two commercial fish stocks, Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus), were examined in relation to environmental variables over Georges Bank in order to demonstrate an approach for predicting fish stocks based on environmental indicators. Historical CTD data and commercial landings data from fishing vessels were used to generate coarse monthly climatologies of catch per unit effort (CPUE), temperature, salinity, density, and stratification. Based on these climatologies, correlations between environmental variables and CPUE were used to establish seasonal, annual, and inter-annual relationships between fish stocks and their environment, and to develop predictive models for the distributions of stocks over Georges Bank. Empirical analysis showed that both cod and haddock exhibit a tendency toward a preferred water temperature which varies seasonally from approximately 5 oC in ... |
