Book Description
This report presents some basic biological information on Monkfish (Lophius americanus), also called goosefish or angler. It describes the Monkfish fishery (landings, and catch and effort data) on the Scotian Shelf and Northeast Georges Bank, and uses summer research vessel survey data to describe the status of the resource (number and weight per tow, size composition, condition, mortality). It also includes a traffic light table that summarizes the indicators of stock status, and provides an outlook for the stock.

Book Description
The EAISSNA database contains information on location and time of spawning, and abundance and distribution of eggs and larvae of marine fish on the Scotian Shelf of North America. 197 scientific publications from 1919 to 2001 were reviewed and original analysis conducted on datasets from Department of Fisheries and Oceans (DFO) Scotian Shelf Ichthyoplankton Program (SSIP) and Fisheries Ecology Program (FEP) for 1976-82 from data archives, providing infonnation on 107 taxa of fish and invertebrates. The database is intended for use in environmental assessment and management activities associated with offshore hydrocarbon development and production and ocean management. Supporting maps and database tables, and possible enhancements and developments including standards based on World Wide Web (WWW) access are also described. The database was developed for and with funding from the Canadian Environmental Studies Research Funds (ESRF), an industry-government body that promotes research in support of hydrocarbon development of Canada's frontier lands. Compact Disks (CD) (report, lists, maps and data) can be obtained from the authors

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
