| Summary: | No abstracts are to be cited without prior reference to the author.A comparative analysis of the fish condition (Fulton’s K) of 11 cod stocks in the North Atlantic in relation to the temperature of their habitat and their reproductive potential is presented. It is shown that the cod stocks in the North Atlantic display different levels of mean condition, which are partly due to the different temperature regimes of their habitats. Cod stocks living in colder waters, e.g. Southern Gulf of St Lawrence, Greenland and Grand Bank cod stocks, were more poorly-conditioned than cod stocks living in warmer waters, e.g. North Sea and Irish Sea. The a-coefficient obtained from a standardised Ricker’s recruitment-spawning stock biomass (SSB) relationship represents the function’s slope at the origin and was defined as an indicator for the recruitment potential of a given stock. The a-coefficients were found to be correlated with the mean condition factors of the stocks in 9 of the 11 cod stocks analysed. This indicates ... |
