Status of B.C. Pacific herring (Clupea pallasii) in 2013 and forecasts for 2014 / J.S. Cleary, N.G. Taylor, and V. Haist. : Fs70-5/2017-014E-PDF

“This document presents stock assessments for Pacific Herring (Clupea pallasii) in British Columbia waters using data current to 2013. Results of the work are intended to serve as advice over the short term to fishery managers and stakeholders on current stock status and likely impacts of different harvest options. As in previous work, an integrated combined-sex statistical catch-at-age model (ISCAM) was applied independently to each of seven stock areas and tuned to fishery-independent spawn index data, annual estimates of commercial catch since 1951, and age composition data from the commercial fishery and from the test fishery charter program. Assessments were done for five major stock areas: Haida Gwaii (HG), Prince Rupert District (PRD), Central Coast (CC), Strait of Georgia (SOG), and West Coast of Vancouver Island (WCVI), and two minor herring stock management areas: Haida Gwaii Area 2W, and WCVI Area 27. Results are summarized as stock reconstructions, status of spawning stock in 2013, and projected spawning biomass in 2014"--Abstract, p. vii.
