Book Assessment of the Georges Bank Atlantic Cod Stock for 2005

Download or read book Assessment of the Georges Bank Atlantic Cod Stock for 2005 written by Loretta O'Brien and published by . This book was released on 2006 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents an updated analytical assessment of the status of the Georges Bank Atlantic cod Gadus morhua stock (NAFO Division 5Z and Subarea 6) for the period 1978-2004 based on analysis of USA and Canadian commercial landings data and research vessel survey data through 2004. Estimates of 2004 fishing mortality and spawning stock biomass, 2005 beginning year stock size, and the precision of the fishing mortality and spawning stock biomass estimates are presented. Total commercial landings of Georges Bank cod in 2004 were estimated at a record low 4,583 mt, a 42% decrease from the 7,963 mt landed in 2003. The USA fleet landed 76% of the total, and the Canadian fleet landed the remaining 24%. Fishery-independent surveys conducted by the Northeast Fisheries Science Center show similar trends in both biomass and numbers of cod since 1982. The 2004 indices remain below the long term average. Autumn recruitment indices of age 1 cod have been below the time series average since 1989 and among the lowest in the time series. Spawning stock biomass declined from about 93,000 mt in 1980 to a record low of 17,340 mt in 1995, and had increased to 30,000 mt by 2001 primarily due to the growth of the 1996 and 1998 year classes. The 2004 estimate of SSB was 22,564 mt, a decrease of 25% from 2001. Fishing mortality doubled between 1979 and 1985, increased to a record high of 1.5 (72% exploitation rate) in 1994, and has since declined to 0.24 (19% exploitation rate) in 2004. The 2004 year class (10.4 million age 1 fish) was strong, but below the time series average (14.7 million age 1 fish). The 2003 year class (21.2 million age 1 fish), however, is the first above average year class since 1989. This year class, and continued low exploitation with minimal discarding, offer a realistic opportunity for the stock to recover toward the SSBMSY of 217,000 mt.

Book Biology and Ecology of Atlantic Cod

Download or read book Biology and Ecology of Atlantic Cod written by Nataliia Kulatska and published by CRC Press. This book was released on 2024-10-31 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic cod is an important fish species in human history and continues to be a major influence on North Atlantic fisheries management, as stock collapses and recoveries impact coastal communities and shelf sea food webs. This book provides an overview of Atlantic cod biology and ecology, focussing on regional differences in life-history and stock dynamics that affect productivity and the challenges faced by management. By comparing the success of management approaches and the local influence of changing climate and food webs, the book highlights the different pressures facing stocks and identifies knowledge gaps across the species’ range.

Book Eastern Georges Bank Cod  5Zjm  551  552  561  562 2005

Download or read book Eastern Georges Bank Cod 5Zjm 551 552 561 562 2005 written by and published by . This book was released on 2004 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the status of Eastern Georges Bank cod based on results from an age structured analytical assessment (VPA) that used fishery catch statistics and sampling for size and age composition of the catch for 1978 to 2003. It includes data on catches, biomass, recruitment and fishing mortality. The outlook for the resource is provided in terms of the possible consequences for alternative catch quotas in 2005 with respect to the harvest reference points.

Book A Report of the 24th Northeast Regional Stock Assessment Workshop

Download or read book A Report of the 24th Northeast Regional Stock Assessment Workshop written by Loretta O'Brien and published by . This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The status of the Gulf of Maine cod (Gadus morhua) stock is reviewed, and estimates of 1997 fishing mortality and spawning stock biomass and the 1998 survivors are presented. Precision of the 1997 fishing mortality and spawning stock biomass estimates for Gulf of Maine cod is also provided. Short-term projections of 1999 landings and resulting 2000 spawning stock biomass at sources of information including: USA landings-at-age estimates, Northeast Fisheries Science Center (NEFSC) and Massachusetts Division of Marine Fisheries (DMF) spring and autumn research vessel survey data, NEFSC sea sample data, and standardized USA commercial fishing effort data. This assessment updates the analyses presented in the 1997 assessment of the Gulf of Maine cod stock (Mayo 1998).
