Ottawa : Fisheries and Oceans Canada, 2000. 23 p. : fig., graphs, maps, tables. Canadian Stock Assessment Secretariat research document, 1480-4883 ; 2000/026 Includes bibliographical references (p. 7). This is the second Groundfish Enterprise Allocation Council (GEAC) survey to investigate in detail the witch flounder catch in 3Ps. One trip to perform the 1999 survey was carried out from 22 November to 2 December 1999. These dates match the 8-17 December 1997 and 30 November to 12 December 1998 time periods for the earlier two years. During the 1999 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 witch abundance and biomass, including age distribution estimates, and interpretation of results are presented. The 1999 estimate numbers alone indicate a large increase in estimated abundance and biomass from 1998; however, the stability in the age and growth distributions seen argue against inferring any kind of large population increase, rather it is more likely a year effect that is the cause of the increases. Three large sets from one stratum area account for approximately 75% of the total reported 1999 catch. gccst Fisheries resources gccst Salt water fish gccst Fishing area gccst Fisheries management Canada.
