Available in PDF, EPUB and Kindle. Book excerpt: Pacific Herring migrate in-shore from feeding areas in the early fall and winter and hold in sheltered bays and inlets in preparation for spawning in late winter and early spring. From November-December, they were fished for food and bait, from March-April for sac-roe, and in April they spawned on kelp. Once the herring have finished spawning, measurements of individual spawnings are made in order to obtain estimates of abundance.

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.

Available in PDF, EPUB and Kindle. Book excerpt: During the 1985-86 fishing season in British Columbia, herring were fished for food and bait from October 1 to December 9, 1985, and for roe from March 23 to April 13, 1986. Measurements of individual spawnings are coupled with data on catch and age composition to allow estimation of the total number of fish present at the beginning of the season, the proportion taken by the fishery, and the strengths of the various year classes. The data are also used to forecast the amount of herring that will return to spawn the following year. Data are presented on these fisheries, which along with biological and management implications are used to establish fishing quotas for each of the fishing license areas.
