Recruitment of short-finned squid in the Northwest Atlantic Ocean and some enviornmental relationships
We found that trends in short-finned squid recruitment were similar among all three Northwest Atlantic fishery areas. This suggests that some broad-scale mechanisms regulate squid recruitment to all fishery areas in a coherent manner. It is also evident that recruitment variability increases to the...
