Abstract

Scomberomorus guttatus is a large pelagic fish commodity in Pangandaran Regency. It has the highest amount and production values, therefore it needs to be maximally utilized but remains its sustainability. The purpose of this research is to determine the most selective fishing gear for Scomberomorus guttatus commodities based on the frequency of Scomberomorus guttatus length, the proportion of the main catch and by-catch in Pangandaran Regency for sustainable and environmentally friendly capture fisheries management. The data used in this study are the number of catches, catch weight and length of the Scomberomorus guttatus catches from gillnet, longline, and beach seine. Data used in research collected during November 2018-January 2019 in Pangandaran Regency. Analysis data used in the study is the analysis of the selectivity of the types of catches and the selectivity of the length of the catchable Scomberomorus guttatus from each of fishing gears. The results showed that of the three fishing gears used to catch Scomberomorus guttatus, gillnet is the most selective and productive fishing gear for utilizing Scomberomorus guttatus commodity because it has a 43,2% of main catch, 84,6% of the feasible Scomberomorus guttatus size. Longline is a fishing gear that is only selective to the length size of the Scomberomorus guttatus that has a percentage of decent size catch equal to 86,4%, while beach seine isn't selective fishing gear and unproductive for Scomberomorus guttatus commodities due to it designed to catch a demersal fish.
