Growth, biomass, and production of juvenile Atlantic salmon ( Salmo salar L.) in two Miramichi River, New Brunswick, tributary streams
The production rate of juvenile Atlantic salmon (Salmo salar) was estimated at four sites in two tributary streams of the Miramichi River, New Brunswick, during the period September 1976 to October 1978. Annual production ranged between 0.27 and 5.12 g∙m −2 ∙year −1 . Growth was largely restricted t...
