In relation to the achievement of the target SDG’s No. 14, the sustainable shark fisheries management need to implement. As a part of the tuna fisheries by-catch, a high number of shark resources have been caught in the Indian Ocean waters. One of the main vessels of tuna catchers in the Southern Indian Ocean of Java is the tuna longline from Cilacap. This paper aims to analyze the shark by-catch of tuna longline in the Indian Ocean in the south Java that landed in Cilacap. The research data was obtained from daily recording activities of fishing vessel loading activities by Cilacap Ocean Fisheries Port staff during the period of 2013-2017. The analysis was done through data tabulation, graphical approaches, and data trend analysis through the availability of time series data. The data analyzed include fleet development, fishing ground, catch composition and CPUE value. The results of the analysis show that there are about eight species of sharks that are by-catch of tuna longline from Cilacap. The highest shark by-catch occurred in April with CPUE averaging 9 kg/day/vessel. The blue shark (Prionace glauca) is the dominant shark catch which reaches 66% of the total sharks catch.
This paper aims to describe the Fish Aggregating Devices (FADs) fisheries in Indonesia and its relation to sustainable fisheries management. On tuna fishing, FADs are widely used as a tool to attract fish. FADs uncontrolled development is feared to have an impact on the sustainability of fish resources. We found that most of the fish caught around FADs are still juvenile. Deployment FADs can also interfere with the swimming pattern of tuna resources. This is negatively affecting the sustainability of tuna resources. However, from the social and economic aspects, FADs provide significant benefits for fishing communities. The Government has imposed regulations on FADs but not yet implemented. The objective of SDG's in the management of tuna fisheries associated with FADs can be implemented through the application of RFMO regulations. Findings from this paper can be used for policy recommendations for the management of sustainable FADsfisheries. , 0 (2018) E3S Web of Conferences
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
