Abstract

AbstractThe selectivity of the fishing gear is defined as the ability of the fishing device to obtain specific fishing targets by type and size during the capture process and allow all unwanted by-catch catches to be passed unscathed (FAO, 1995). The purpose of this study was to find out the selectivity of the mesh size and the composition of the catch of drift gillnets in PPN Sungailiat. The result of this research is a drift gillnet with a mesh size of 8.89 cm caught tuna with a fork length range of 32 - 45.7 cm and the highest catch ratio was caugth at fork length (L). = 37.7 cm with Sa = 0.999289326.Meanwhile, mesh size of 10.16 cm caught tuna with a fork length range of 36.6 - 50.3 cm and the highest catch ratio was caught at fork length (L) = 43.3 cm with Sb = 0.999974108.So that drift gillnet with a mesh size of 10.16 cm are more selective than drift gillnet with a meh size of 8.89 cm,because the L value is greater and the S value is closer to 1. As well as catching more large fish that are fit to catch (≥ 40 cm).Keywords : Fishing Gear; Selectivity; Sungailiat; Drift Gillnet

Abstract

Selectivity of fishing gear is defined as the ability of  fishing  gear  to  achieve certain fishing targets according to type and size during the fishing process and allows all unwanted bycatch to be released without injury. The  purpose of this study was to determine the  selectivity  of  mesh  size  and composition of drift gill net in PPN Sungailiat. The result  of this research is that  the drift gill net with mesh size of 8.89 cm catches tuna with a fork length range of 32 – 45.7 cm and the highest catching ratio is found in the fork length (L) = 37.7  cm with Sa = 0.999289326. Meanwhile, the mesh size of 10.16 cm caught fish that had a fork length range of 36.6 – 50.3 cm and the highest catch ratio was for the fork length (L) = 43.3 cm with Sb = 0.999974108. So that the drift gill nets with mesh size 10.16 cm are more selective than drift gill nets with a mesh size of 8.89 cm, because the L value is larger and the S value is closer to 1.  As  well  as  catching more large fish that deserve to be caught (≥ 40 cm).
