Stow net fishery is one of the important fishing methods in southern Yellow Sea. Based on the 2006-2009 data from the stow net fishery resources survey in the southern Yellow Sea in spring, and by using the generalized linear model (GLM) and generalized additive model (GAM), this paper quantitatively analyzed the relationships between the catch distribution of Pseudosciaena polyactis and Lophius litulon and the environmental factors such as year, position, water depth, and sea surface temperature (SST). Compared with GLM model, GAM model could better explain the relationships between the spatiotemporal distribution of the catch per unit effort (CPUE) of P.
