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.

This book was released on 1994 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: A workshop was held to explore the need for an ecological research and monitoring site in the Atlantic Maritime Ecozone, with particular reference to the land/sea/atmospheric interface (coastal zone), and to explore the suitability of the Huntsman Marine Science Centre, in conjunction with the Fisheries and Oceans Canada Biological Station, as the administrative center of such a site. This publication presents summaries of the working group discussions on estuarine and marine ecosystems, terrestrial and aquatic ecosystems, and ecosystems data management, and includes papers presented at the workshop. The topics of the papers include ecosystem and wildlife monitoring, atmospheric variables and trees, research and monitoring programs, sulfur dioxide deposition, lakewater chemistry, benthic monitoring, and nutrient cycling patterns.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents an updated analytical assessment of the status of the Georges Bank cod Gadus morhua stock (NAFO Division 5Z and subarea 6) for the period 1978-1999 based on analysis of USA and Canadian commercial landings and effort data and research vessel survey data through 1999. Estimates of 1999 fishing mortality and spawning stock biomass, 2000 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 1999 were estimated at 9,880 mt, a 12% increase from the 8,800 mt landed in 1998. The USA fleet landed 82% of the total, and the Canadian fleet landed the remaining 18%. Commercial landings per unit of standardized effort (LPUE) declined to a record low in 1995, then increased in 1996 and 1997 and have remained relatively stable through 1999. Fishery-independent surveys, conducted by the Northeast Fisheries Science Center, show a similar decline in both biomass and numbers of cod since 1982. The 1999 indices remain well below the long term average. Recent recruitment indices of age 1 cod remain among the lowest in the time series, however, indices of age 2 fish indicate that the 1996 year class is about average. Spawning stock biomass declined from about 92,000 mt in the early 1980s to a record low of 20,000 mt in 1994 and has since increased to 35,000 mt in 1999. Mean biomass exhibits similar trends. Fishing mortality doubled between 1979 and 1985, increased to a record high of 1.42 (70% exploitation rate) in 1994 and has since declined to 0.22 (18% exploitation rate) in 1999. Recruiting year classes have been well below the long term average (16 million fish) since 1991.
