Seasonal Distribution, Abundance, and Growth of Larval Capelin ( Mallotus villosus ) in the St. Lawrence Estuary and Northwestern Gulf of St. Lawrence
Capelin (Mallotus villosus) larvae in the St. Lawrence estuary and northwestern Gulf of St. Lawrence were most abundant in 1974 and 1975 in the upper estuary in early June; this coincided with the spring peak in primary production. A spectacular decline (>99%) in larval abundance between June...
