Generalized additive models (GAMs) was used for evaluating the data set. Variables used in model were age of angler (X1), experience of angler (X2), annual total fishing day (X3), total value of fishing equipment (X4), monthly total income of anglers (X5), household number of anglers (X6) and CPUE of anglers (Y). Effect of all variables on the CPUE were founded not significant (p>0.05), except “Annual total fishing day” (p>0.05). The variables such as monthly total income of anglers, experience of angler, total value of angling equipment and annual total fishing day positively affected CPUE.
