This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This document details the data and analyses used to assess the status of the west coast of Newfoundland (NAFO Division 4R) spring- and fall-spawning herring stocks. The present stock assessment took place on March 1-2, 2022 and provides advice for the 2022-2023 fishing seasons. The data and knowledge available are insufficient to quantitatively assess the status of the resource. However, the main results of this assessment indicate that maintaining the TAC at status quo should not pose any significant risk to the two herring spawning stocks in Division 4R in the short term. Maximum exploitation rates in 2020-2021, estimated as the ratio of the TAC over the highest biomass index estimated in the acoustic survey, were low (
