Sero is a fishing device made of statically operated nets to catch migratory or migratory fish on the beach. Based on themesh size of the mesh used raises a problem about environmental friendliness and raises the question of what net meshsize is effectively used by sero fishermen. The purpose of this study was to determine the effect of differences in the sizeof the crib on the catch and selectivity with the hypothesis that the size of the mesh size crib sero a significant effect onthe chance of catching fish. The benefit of providing information regarding the size of the mesh size is best used in serofishing 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 researchmethod is the trial of fishing by applying a selectivity approach to trawl fishing gear. The data collected is primary andsecondary data taken by fish catching, interview and survey methods. Data analysis in the form of comparison of catchcomposition, analysis of variance (ANOVA) on catches and selectivity analysis. The dominant fish caught is Upeneussulphureus. The average proportion of captive turtles that is worth catching is for the size of the mesh size 4 cm, theproportion is more than 75 percent, while the size of the mesh size 3 cm is still below 50 percent. Selectivity analysisshows that to catch Upeneus sulphureus, it is better to use a net mesh greater than 4 cm so that the sustainability of theturmeric resources is maintained
