Factors controlling abundance of downstream juvenile pink salmon ( Oncorhynchus gorbus с ha ) in the Mi River
Nonlinear multiplicative model is developed that describes dependence of the pink salmon juveniles abundance in the Mi River (Amur Estuary) on number of their parents and some meteorological factors. The spawning stock is the most significant factor that explains 44.7 % of the abundance dispersion....
