This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spring survey, previously used to estimate biomass and abundance, may not include a substantial portion of the population, and thus represents only the portion of the stock that occurs within the surveyed area. [...] Of these, thorny skate (Amblyraja radiata) is dominant, comprising about 90% of the skates caught in research survey trawls on the Grand Banks during 1951-1998, and about 80% of skate species taken in commercial offshore catches on the Grand Banks and northeastern Shelf to the north, 1981-1998 (Kulka et al. [...] Within the managed area of the Grand Banks (NAFO Divisions 3L, 3N, 3O, and Subdivision 3Ps), a relatively continuous distribution and lack of physical barriers suggest that they constitute a single reproductive entity: concentrating on the shallow section of the Grand Banks, and extending from the Tail of the Banks outside of Canada's 200-mile-limit to the southern edge of St. [...] After the change in research survey gear (denoted by a grey bar and a separation in the time series on the x-axis) to Campelen, relative biomass was approximately 2.8 times greater (comparing the average of 1994-1995 and 1996-1997); indicating that the Campelen trawl was considerably more efficient in capturing thorny skate. [...] Most of the thorny skate were found in Divisions 3N, 3O, and Subdivision 3Ps: approximately 60% in the 1970s, and 90% following its decline in the early 1990s.

This book was released on 1999 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the population biology and fishery management of elasmobranchs at regional, national and sub-regional levels - in Atlantic Europe, the United States, the Caribbean, Guatemala, South Africa, Uruguay, the Falkland Islands, the Seychelles, two states in India, the Maldives, Malaysia, Australia, New Zealand, Japan, Fiji and Ecuador. Regional accounts are given of management of Galeorhinus galeus, deepwater sharks and elasmobranch considerations of a tuna commission. NGO elasmobranch activities are described and an analysis of the quality of the relevant data in the FAO Nominal Catches and Landings Data Base. The topics of the resource, fishery and associated species, current status of fisheries and harvesting processes are described together with the evolution of the catch, fleet, fishing effort, commerce, fishery markets and revenues from the fishery. Comments on the economics of the fishery and nature of the workforce are also given. In relation to fisheries administration, management objectives and national fisheries policies are described and the manner of the planning process. Where applicable, the objectives setting process, relevant stakeholders and the handling of management negotiations are noted. The nature of gear restrictions and their effectiveness together with vessel regulations and where they exist, on catch, closed seasons, effort limitations, etc., are described Where management planning occurs, the provision of resource management advice together with a description of the departments involved and management activities are described. Several papers review stock assessment activities plus descriptions and analyses of the biological advice review process with comments on the sustainability of the resource. National accounts describe the relevant law and enforcement processes. The report consists of two parts.

This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The degree of offshore migration (proportion off the bank in the winter/spring) appears to have intensified during the period of decline of the population (mid-1980's to the early 1990's). [...] About 90% of the biomass is now concentrated in 20% of the area (near the edge of the Southwest Grand Banks). [...] The spring survey, previously used to estimate biomass and abundance, may not include a substantial portion of the population, and thus represents only the portion of the stock that occurs within the surveyed area. [...] The biomass in the survey area (3LNO) is higher in the Spring than the Fall, especially in the years 1993 and 1998. [...] However, the area occupied by skate decreased since the 1980s and the largest decline occurred in the most recent years and on the northern half of the bank.
