Efficiency of Natural Propagation of the Pink Salmon ( Oncorhynchus gorbuscha ) in McClinton Creek, Masset Inlet, B.C.
Through the medium of specially-designed counting fences, records have been maintained of the adult pink salmon, Oncorhynchus gorbuscha, spawning in McClinton creek, Masset inlet, B.C. from 1930 to 1942, of the eggs available for deposition each season and of the fry resulting from these eggs. A los...
