Assessment of the 4T herring stock / by Lynn Cleary. : Fs70-8/82-47E-PDF
"Landings from the 4T herring stock declined from 270 000 mt in 1970 to 40 500 mt in 1980 and in 1981, due to quota restrictions, to 22 000 mt. An analysis of the commercial catch rates revealed that the abundance indices from the purse seiner fishery have slightly increased after 1979-1980, at which point they had reached a historical low. However, the catch rates from the inshore fishery are relatively stable, with some indices showing a slight increase from 1980 to 1981, and others a slight decrease. The groundfish research cruise catch rate has been declining since 1978."
