Description

Abstract: The Oregon fishery for Loligo opalescens is expanding at a rapid rate. Fishing effort and efficiency are increasing; purse seines are used most frequently to catch squid. In 1985 catch per trip averaged 27.0 thousand lb. Six vessels accounted for 77% of the 1.75 million lb landed. Ex-vessel price averaged $350 per ton. L. opalescens caught off Oregon apparently have different biological characteristics than squid caught in California. Females in an aquarium laid an average of 23 egg capsules per animal. A total of 700 egg capsules collected in the field yielded an average of 98 + 2 (95% CI) eggs per capsule. The mean dorsal mantle length of L. opalescens sampled diminished with time. Females had longer dorsal mantle lengths than males. The sex ratio of all samples collected is weighted toward males. Storage tests revealed that squid whole weights decline with time when frozen. Length to weight ratios of spawning female squid indicated that three different groups of squid entered the harvest area to spawn.
