Description

Abstract: Commercial landings of the market squid (Loligo opalescens) increased from 113,000 lb, produced by 7 vessels in 1982 to almost one million lb produced by 13 vessels in 1984. A research project was established to provide information to manage the new fishery. Observers were placed on fishing vessels to identify problems associated with incidental catch of the gear, gear impacts on squid egg capsules, and gear conflicts. Observers saw few problems associated with the level of harvest and activity in 1984. Samples of 200-250 squid were collected three times a week to obtain estimates of the biological characteristics of spawning squid in Oregon. Results of the analysis indicate that a sample size of 100-150 animals would provide sufficient precision in estimating dorsal mantle lengths. The average dorsal mantle length of squid collected was 110.8+-0.5 mm (95% CI). Females were significantly (P < 0.05) larger than males. The average dorsal mantle length of samples declined throughout the season. Average sample weights declined then increased in the second area of harvest, suggesting that new groups of squid moved into the area to spawn.
