The Greenland halibut fishery in the Gulf of St. Lawrence / by W.R. Bowering. : Fs70-8/80-24E-PDF
"Landings have average 600-1000 t up to 1974 and subsequently increased to 4000 t in 1977 and 1978 to a high of 10,000 t in 1979. The fishery is made up of more than 80% 6-10 year old fish very similar to the strong recruiting year-classes found in the Labrador-northeast Newfoundland stock. Biomass surveys indicated stability in Division 4S with substantial reductions in biomass in Division 4R. There was no estimate of biomass in Division 4T which accounted for 60% of the catch in 1979. Fishing mortality estimates were similarly high from both commercial and research data. It was determined that the levels of fishing mortality do not reflect estimates of stock abundance in the Gulf of St. Lawrence unless there is significant immigration from other areas"--Abstract.
