An assessment of the Gulf of St. Lawrence herring stock complex / by L. Cleary.: Fs70-8/81-23E-PDF
"Landings from the 4T herring stock declined from 270 000 t in 1970 to 40 500 t in 1980. Recently, the fishery has been sustained mainly by the 1974 year-class. The catch matrix shows a decreasing trend in the proportion of mature fish in the catch (6 years old: 91% in 1969, 22% in 1980), while no particularly strong recruitment is obvious since the 1974 year-class entered the fishery. An analysis of the catch rate data reveals that for both the commercial inshore and offshore fishery and groundfish research cruises catch rates are at a historical low, except for the Pictou Island fall gillnet fishery"--Abstract.
