American plaice catch results from fall 1999 survey in NAFO division 3Ps / John McClintock.: Fs70-1/2000-025E-PDF
This is the second Groundfish Enterprise Allocation Council (GEAC) survey to investigate in detail the American plaice catch. 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 Fisheries Form System (FFS) and otoliths were collected for subsequent aging. Catch statistics, length and age distribution, and stratified analysis estimates of American plaice abundance and biomass, including age distribution estimates, and interpretation of results are presented. The 1999 results indicate that the strengths of all year classes from 1987 onwards are all increased from the corresponding 1998 survey. The 1989 to 1991 year classes in particular are up noticeably from the 1998 survey. Total plaice abundance and biomass estimates for the 1999 survey are three times larger than for 1998; however, the increases can be accounted for by one stratum area of the survey. Most likely it is a year effect that is the cause of the increases.
