Greenland halibut in the Gulf of St. Lawrence : from immigrants to emigrants / by W.R. Bowering.: Fs70-8/81-55E-PDF
"Landings have increased from less than 1000 t in 1969 to a high of 9000 t in 1979. Catches in 1980 were about 6800 t. Up until 1969, 55-66% of the catch was taken in Div. 4S by gillnetters with 30% taken by trawlers in Div. 4R. Since then more than 65% has been taken by gillnetters in Div. 4T. Biomass estimates indicated a general reduction since 1978 based upon winter surveys. Considering the similarity between year-class abundance within the Gulf of St. Lawrence and those in the labrador region there may be considerable immigration to the Gulf area from Labrador through the Strait of Belle Isle and emigrationfrom the Gulf area when these fish approach maturity."--Abstract.
