| ABSTRACT A greater knowledge of the selectivity of fishing gear allows determining the capacity to select the sizes and shapes of the species caught, in addition to providing useful information for their conservation and use. This study determined the selectivity parameters of gillnets (7.0, 7.6 and 10.2 cm of mesh size) and J hooks (n.° 7, 9 and 10), used in the artisanal catches of the blue runner (Caranx crysos), in different fishing sites in the Santa Marta region. The SELECT method was used to determine the selectivity parameters, while the Kurskall-Wallis test was used to evaluate differences in the catch per unit of effort (CPUE) between the mesh sizes and the evaluated hook gauges. The results demonstrate that the log-normal model better describes... |
