ANALISIS SELEKTIVITAS DAN HASIL TANGKAPAN KUNIRAN (Upeneaus sulphureus) PADA ALAT TANGKAP SERO DENGAN UKURAN MATA JARING BERBEDA DI PERAIRAN PANTAI TELUK MANDAR POLEWALI MANDAR SULAWESI BARAT

Abstract

Sero is a fishing device made of statically operated nets to catch migratory or migratory fish on the beach. Based on the
mesh size of the mesh used raises a problem about environmental friendliness and raises the question of what net mesh
size is effectively used by sero fishermen. The purpose of this study was to determine the effect of differences in the size
of the crib on the catch and selectivity with the hypothesis that the size of the mesh size crib sero a significant effect on
the chance of catching fish. The benefit of providing information regarding the size of the mesh size is best used in sero
fishing gear. This research was conducted from November 2017 - September 2018 in the coastal waters of Mandar Bay,
West Sulawesi. The main tools used are 3 sero units, 1 motor boat unit, measuring board, and thread. The research
method is the trial of fishing by applying a selectivity approach to trawl fishing gear. The data collected is primary and
secondary data taken by fish catching, interview and survey methods. Data analysis in the form of comparison of catch
composition, analysis of variance (ANOVA) on catches and selectivity analysis. The dominant fish caught is Upeneus
sulphureus. The average proportion of captive turtles that is worth catching is for the size of the mesh size 4 cm, the
proportion is more than 75 percent, while the size of the mesh size 3 cm is still below 50 percent. Selectivity analysis
shows that to catch Upeneus sulphureus, it is better to use a net mesh greater than 4 cm so that the sustainability of the
turmeric resources is maintained.
