Abstract/Description: | The gear selectivity and fishing power of different mesh sizes were investigated using experimental catch data of carangids Caranx sexfasciatus and Caranx tille. The selectivity and residual curves were generated using four different individual uni-normal and bi-normal functions with four different mesh sizes. Selectivity parameters were estimated using the SELECT model which has been implemented in the software called GILLNET (Generalized including Log-Linear N Estimation Technique). Model deviance, Dispersion parameter and Residual plots were used to determine the best fit of the data. The results demonstrated that bi-normal model and uni-normal log-normal yielded good fit for C. Sexfasciatus and C. tille respectively. Mesh sizes 14 and 14.5 cm performed better than the modeled in both the catch data. Modal length increased with mesh sizes. Bi-normal model yielded narrow selection range while log-normal model was of wider range. Shape and size of the selectivity curves were identical and uniform in size. Over dispersion was common in all selectivity models which in turn showed lack of fit irrespective of the models. |
