Analisis Keberlanjutan Perikanan Tongkol Lisong (Auxisrochei) Di Selat Lombok

Abstract

One of the biggest fisheries products in NTB is tuna. Mataram City is one of the largest tuna production locations in NTB. This research aims to determine the sustainability status of tuna fish and the biological condition of its fisheries in the waters of the Lombok Strait and to determine the condition of the tuna fish population in the waters of the Lombok Strait. The method used in this research is a descriptive dependent survey method. In this research, data was collected through data collection techniques by sampling. Fish samples were obtained from the waters of the Lombok Strait which were landed by fishermen in Bintaro Village, Mataram Selatan, and Tanjung Karang, Mataram City, West Nusa Tenggara Province. Data on the length and weight of the fish were then analyzed for the level of sustainability using the parameters of age group, suitability for consumption, suitability for maturity, and suitability for catching. Biologically, the Lisong tuna fishery in the Lombok Strait can be categorized as a sustainable fishing activity because most of the fish caught are adults. The population of tuna caught by fishermen is not threatened because most of them have mature gonads.
