Book Description
This report describes the Atlantic wolffish (Anarhichas lupus) fishery on the Scotian Shelf, Georges Bank and in the Gulf of St. Lawrence and provides an assessment of the resource. It includes information on landings, mean number per tow, mean weight per tow, length frequency, condition, biomass, area occupied and mortality. The report contains a traffic light table that summarizes the indicators of stock status, and it provides an outlook for the stock.

Book Description
The Accord for the Protection of Species at Risk ( 1996) and the Species at Risk Act (2003) arc initiatives of the Federal government that were established to provide protection and recovery for species at risk in Canada. Fisheries and Oceans Canada (DFO) is the primary source of information and expertise concerning the assessment of extinction vulnerability of aquatic species. The Mari times Region of DFO is responsible for compiling biological information concerning status and potential extinction risk of marine fish species that support fisheries along the Scotian Shelf, northern Georges Bank, and in the Bay of Fundy. Given the breadth and importance of this task, it is necessary that a method for rapid analysis be developed that allows for the assessment of potential extinction vulnerability of fish species, and uses assessment criteria that are explicitly defined and relevant to marine species in Canada. The approach undertaken by the Maritimes Region was to develop a scoring matrix that (1) quantifies the dynamics of a species' abundance and distribution and allows for rapid determination of whether or not that species may be at risk of extinction, and (2) allows for easy comparison across taxa thrnugh standardization of scoring. The intention behind the matrix was to create a more intuitive ranking scheme than has been used in the past. The potential extinction vulnerability of each species is graded out of 100. A high score represents a relatively high risk of extinction or extirpation from Canadian waters. Species assigned high scores by this rapid process can then be subjected to further, indepth evaluation. The criteria and conditions for the matrix were derived from criteria used by COSEWIC, and DFO's General Status Pilot Project. However, a new set of conditions were developed for some criteria to address several of the deficiencies that existed in the General Status approach, and to accentuate factors that may of greater significance to extinction vulnerability than to the assessment of current abundance. This exercise was intended to test the validity and utility of a matrix approach for rapid assessment of extinction vulnerability and ease of comparison among species. The matrix is not intended to replace the formal assessment process, but to identify species that may need higher priority for a formal COSEWIC assessment. A prioritized candidate species list was created based on the results of the matrix analysis

Book Description
This publication comprises the proceedings of an international workshop convened in St. John's, Nfld, Nov. 26-29, 1979. The purpose of the workshop was to discuss the results of recent multispecies research, its applications to management, and to consider future directions for research in this field. A total of 26 papers were presented, including a combination of experience papers, state-of-the-art review, and new scientific findings. Sequential sessions were held on fisheries systems research by the Department of Fisheries and Oceans, multispecies considerations in fisheries research and management advice in the ICES area, species interactions in the Northeast Pacific and Northwest Atlantic, fisheries interactions, and applications to fisheries management. The workshop concluded with a substantial discussion of implications of present knowledge for advice to fisheries managers and implications for research program planning. The Workshop Report comprises the Chairman's opening remarks, a report on main elements of discussion in the sessions, and a summarization of workshop conclusions.
