Available in PDF, EPUB and Kindle. Book excerpt: Pacific herring migrate to inshore areas from offshore feeding grounds in the early fall and winter and then hold in sheltered bays and inlets in preparation for spawning in late winter and early spring. The food and bait fishery is conducted in November/December when the herring first move inshore and the fat content is high, and the sac-roe and spawn-on-kelp fisheries occur in March/April during the spawning season when gonad development is near or at maximum. When the herring have finished spawning, measurements of individual spawns are made to obtain estimates of abundance. This information is combined with data on catch and age composition to estimate the overall herring abundance and age class strength and to forecast the amount of herring that will return to spawn during the next year. This report presents information on the 1989/90 herring fishery and spawn abundance by district.
