Abstract
Evidence was obtained that spring and autumn herring fisheries in the southern Gulf of St. Lawrence are supported by two discrete stocks. Samples from the two fisheries taken in 1965 through 1969 differed in length- and age-frequency distributions, year-class composition, growth rate, spawning time, and mean numbers of pectoral and dorsal fin rays.Keywords
