1979 assessment of cod in divisions 4T and 4Vn (Jan-Apr) / by David F. Gray.: Fs70-8/79-21E-PDF
"Catches from this stock reached an all time recorded high of 110 thousand t in 1956 apparently as a result of the reaction of the cod biomass to the destruction of pelagic stock biomass by epizootic disease. From that point catches declined to 41 thousand t in 1967. However reported catches then climbed to about 60 thousand t per year in the early 1970's primarily due to an increase in interest in the 4Vn winter fishery by foreign countries and large Canadian otter trawlers. With dropping catch rates and decline in numbers estimated from research tows, there was an indication that the population was being exploited at fishing mortalities above sustainable levels"--Introduction.
