Second Year Results of Surveys Directed at cod in NAFO Division 3Ps.

By J. McClintock

Abstract

To enhance the fisheries research database in NAFO Division 3Ps, the Groundfish Enterprise Allocation Council (GEAC) has funded surveys during fall 1997 and fall 1998 directed at cod. The continuing intent is to create a series of annual fall surveys in 3Ps to complement current resource assessment activities carried out by the Department of Fisheries and Oceans (DFO). GEAC funded and performed the surveys with scientific guidance from DFO in the design and execution of a stratified random survey and the associated sampling. The data collected during these surveys have been subsequently analysed on behalf of GEAC for the express intent of providing this information to DFO, for their databases and their assessment work. This is the second such GEAC survey in 3Ps following on the 1997 survey (CSAS Research Document 99/20). One trip to perform the 1998 survey was carried out from 30 November to 11 December 1998. This time period matches the 8-17 December period in which the 1997 stratified random survey was conducted. During the trip, set details and length frequencies were logged in the DFO FFS system and otoliths were collected for subsequent aging. Catch statistics, length and age distribution, and stratified analysis estimates of cod abundance and biomass, including age distribution estimates are presented.
