MANAGEMENT STATUS OF MACKAREL (RASTRELLIGER SP.) RESOURCES IN THE FISH RESOURCES DOMAIN OF REMBANG DISTRICT, CENTRAL JAVA PROVINCE OF INDONESIA, AS A PART OF ECOSYSTEM APPROACH OF FISHERIES MANAGEMENT

Abstract

Mackerel is an economically high and dominant fish caught in the waters of Rembang District. Its production volume is the third largest in 2017, by 2,013 tons. Mackerel is commonly caught using a small pelagic – one boat operated purse seine with a 30 GT boat down. Intensive fishing efforts will endanger the population of this fish, so management is needed so that fish resources can be sustainable. The study was conducted in Rembang District to see the status of mackerel (Rastrelliger sp.) resource management in the domain of fish resources with an ecosystem approach. It lasted from December 2018 to February 2019. It employed a survey method. The indicators used in the domain of fish resource are standard CPUE, trends in fish size, proportion of juvenile fish caught, catch species composition, range collapse of fish resources, and ETP species. The results showed that standard CPUE, trends in fish size, catch species composition, proportion of juvenile fish caught, and ETP species are in good condition with a score of 3 (green modeling flag). While the range collapse of fish resources is in a moderate condition, with a score of 2 (yellow modeling flag). The composite score of 97 shows that management status of Mackerel resources in the domain of fish resource in Rembang District is in very good condition (dark green flag modeling).
