An update of the status of the witch flounder resource in NAFO subdivision 3Ps / by W.R. Bowering.: Fs70-8/87-34E-PDF

"Catches of witch flounder in Subdiv. 3Ps during the last 10 years (except for 1977) have been less than 1000 t annually and in more recent years have been less than 500 t annually. The fishery is made up of a by-catch fishery on St. Pierre Bank by otter trawlers and a mixed groundfish fishery in Fortune Bay mainly by Scottish seiners. The maximum age in the population has declined from 22 years to 14 years between 1976 to 1986, but has been relatively stable since 1980. Biomass estimates from surveys are highly variable and do not indicate any particular trends. Mortality estimates indicate that very little fishing mortality has occurred in recent years, however, despite this the age span of the population has not increased"--Abstract, page 2.
