Multi‐timescale interactions between pink and chum salmon catch per unit effort in the Bering Sea
Abstract Based on generalized linear models, interspecific interactions were identified between chum and pink salmon. In addition, the effects of sea surface temperature and location on the variability of catch per unit effort ( CPUE ) of chum salmon from gill‐net surveys carried out between 1972 an...
