Available in PDF, EPUB and Kindle. Book excerpt: "During the past five years catches from the Newfoundland west coast herring stock have risen steadily reaching almost 19,000MT in 1980. While the purse seine catch has remained stable for the past few years the gillnet component continued to show some expansion. The catches from both spawning components were dominated by age-groups 11+ indicating that recent recruitment has not been exceedingly strong. The only exception being the 1974 year-class of spring-spawners which is estimated at 1/4 the strength of the 1968 year-class."--Abstract.

This book was released on 1982 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Catches from the Newfoundland west coast herring stock fell from 19,100 t in 1980 to 13,200 t in 1981 with a reduction in catch occurring in all gear components. The catches from both spawning groups are dominated by age group 11+ with the only change in the age frequency distribution from 1980 being an increased contribution from the 1977 year-class by both spawning groups. Due to the predominance of old fish in the autumn-spawning component the values of natural mortality were re-examined."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: "Both the inshore and mobile components of the herring fishery in the Newfoundland west coast stock area experienced an increase in catch in 1978 despite a declining trend in stock abundance (Moores and Winters 1978). Total catch in 1978 was 15,922 metric tons, an increase of 30% above the 1977 catch of 12,286 m tons (Table 1). The large increase in catch is primarily attributable to the inshore components (gillnet, bar seine, trap) which landed 5596 m tons in 1978, double the 1977 catch (2822 m tons)"--Introduction, page 1.

Available in PDF, EPUB and Kindle. Book excerpt: "During the past four years herring catches from the Newfoundland west coast stock have risen steadily from 10,000 t in 1976 to 18,300 t in 1979. Much of the increase in catch is attributable to expansion in the fixed gear component. The age composition of the catch showed an improving recruitment pattern with significant contributions from the 1974 year-class of spring-spawners and the 1973 year-class of autumn-spawners, however, age-groups 10+ remained dominant in the catch from both components"--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: The first section of this paper reviews the herring fishery on the west coast of Newfoundland, including total catches, catches in the purse seine fleet & the gillnet fleet, and target quota allocations. The second section presents information on the biological characteristics of herring from that area, based on samples taken from the commercial fishery. The information includes the proportion of each spawning stock in the commercial catch, age composition of the catch, & condition factor. The third section provides estimated abundance indices for the herring stock based on acoustic surveys, fishery logbook data, and fishermen's questionnaires. The final section discusses the status of the west coast herring stocks and presents a prognosis for the stocks.

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 (

This book was released on 1983 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Although recent tagging studies heve shown the west coast of Newfoundland to be a discrete herring stock area, studies conducted in the early 1970's showed an overlap between the west coast stock and southern Gulf of St. Lawrence herring stock. These studies indicated that the overlap was probably most extensive during the spring in the area of the St. George's Bay"--Abstract.
