Estimation of biomass and yield of the St. Mary's-Placentia herring stock complex / by G.H. Winters. and J.A. Moores.: Fs70-8/79-36E-PDF
"Historical catch statistics for St. Mary's and Placentia Bays (Fig. 1) herring fisheries indicate peak average landings of about 15,000 m tons during the period 1945-50, principally by inshore gears in Placentia Bay. During the 1950's and early 1960's landings dropped substantially to 1000-2000 m tons but began to increase again during the late 1960's due to the expansion of the large purse-seine fleet into these areas. Landings peaked at 6,700 m tons in 1974 and 1975 (mainly from Placentia Bay) and have since declined to about 3,500 m tons since 1977"--Introduction.
