| Summary: | No abstracts are to be cited without prior reference to the author.A high growth rate for Arcto-Norwegian cod (Gadus morhua L.) in the Barents Sea and adjacent areas from the larval stage to the O-group stage enhances survival and ultimately recruitment to the fishery. However, it appears that relatively high growth rates for a cohort through the O-group stage are not continued as the cohort ages. Based on survey data, there is a negative, though not significant, correlation between a cohort’s average length at the O-group stage and its average length as 1 year olds and a significant negative correlation between the average length at the O-group stage and its average length at ages 2 through 9. It appears that the reason for this slowing of growth is that a strong inflow of warm, prey-rich Atlantic water into the Barents Sea from the Norwegian Sea provides favorable conditions for growth and hence survival of the cod larvae and juveniles. But this same strong inflow carries a proportion of the cohort farther ... |
