Evaluation of reef fish status according to domain criteria of fish resources (EAFM) in Labuan Berop

Abstract

The Ecosystem Approach to Fisheries Management (EAFM) advocates a holistic approach to resources management that recognizes maintenance of ecosystem functions and services as a primary objective for fisheries management. There are 6 domains and several indicators to implement EAFM, such as habitat and ecology, fish resources, fishing technology, economy, social, and institution. Among 6 EAFM domains, fisheries resources domain evaluated in Labuan Beropa waters as a basis for fisheries management. We analyzed 6 indicators, there are standard catch per unit effort (CPUE), fish size, juvenile caught proportion, species composition, range collapse, and reef fish density. This study was conducted on April to July 2014. Data were collected by direct observation of the capture caught by fisherman and depth interview with some of respondents. Evaluation results showed that CPUE has decreased slightly (<25%/year) for longline and drastically (>25%/year) for kedo-kedo. In addition, the mean size of catch fish decreased, proportion of juvenile caught are <30% of total catch, composition of target fish was captured are >30% of total catch, range collapse become more difficult than before, and reef fish density was <10 ind/m 2 . EAFM obtained in Labuan Beropa waters generally at moderate category, even though some others still had bad scores which need more management strategies for sustainable utilization.
