This book was released on 1996 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herring are an important component of the British Columbia commercial fishery with catch records dating from 1877. Since 1983, herring fisheries have been managed with a fixed quota system in which catch levels are determined prior to the season based on a fixed percentage of forecast stock abundance. This report presents stock assessments from escapement and age-structured analytical models that were developed explicitly for B.C. herring. Both models reconstruct stock abundance from 1951 to last year and forecast pre-spawning abundance for the coming year. Forecasts of recruit spawners are presented as poor, average and good, based on historical recruitment levels. The report does not discuss the development and evaluation of empirical models for forecasting recruitment.

This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, herring stock abundance in British Columbia waters was assessed for 2002 and forecasts were made for 2003 using two analytical methods, an age-structured model for the major stock assessment regions and an escapement model for the minor stocks. These models have been applied to assess herring abundance since 1984 and changes were introduced to account for temporal change in the spawn index. All available biological data on total harvest, spawn deposition, and age & size composition of the spawning runs were used to determine current abundance levels. Forecasts of the pre-fishery spawning stock biomass are presented for both models.
