The potential of fisheries resources in Indonesia is 9,931 million tons per year, with the highest potential being in WPP 718 of 1,992 million tons / year (20%), in WPP of 1,228 million / year (12%) and in WPP 711 of 1,143 million tons / year (12%). Bigeye Tuna (Thunnus obesus) is one of the leading commodities from the fisheries sub-sector which is commonly consumed both locally and export. Cilacap Ocean Fishery Port (PPS), Cilacap Regency, is one of the Bigeye Tuna (Thunnus obesus) fish landings caught from the Indian Ocean. This study aims to find out information on the long-term weight ties of Bigeye Tuna (Thunnus obesus) captured from the Indian Ocean and landed at PPS Cilacap, Central Java. According to Cilacap PPS (2014), Bigeye Tuna (Thunnus obesus) fish is one of the large pelagic fish species with the most catches after skipjack fish from all landed fish. The results of the analysis of the relationship between weight weights show that the growth pattern of big eye tuna (Thunnus obesus) is allometric negative (b <3). In fisheries biology, this long-weight relationship of fish is one of the information that needs to be known in terms of fisheries resource management.

Prediksi musim dan tingkat pemanfaatan sumberdaya ikan di perairan Selat Sunda sangat penting untuk mengontrol eksploitasi yang berlebih. Untuk itu pendekatan berbasis agen (agent based approach) dari perubahan musim dan faktor input lainnya terhadap perilaku nelayan perlu dikaji. Penelitian dilakukan di Lempasing dari nelayan yang menangkap di Selat Sunda dengan teknik purposive sampling terhadap nelayan agen (purse seine) dan nelayan nonagen (non purse seine) dengan software Poseidon 1.0. Pola musim penangkapan ikan pada musim timur, daerah penangkapan nelayan agen semakin lama akan semakin mengecil dikarenakan faktor alam dan juga kenaikan harga solar. Nilai produksi dari nelayan agen mengalami penurunan diakibatkan adanya ketidakseimbangan harga yang jual ikan. Pengaruh produksi terhadap pembentukan harga tidak terlalu berpengaruh dan relative linier. Analisis agent based model memberikan gambaran strategi berupa pengaturan upaya penangkapan, konsumsi bahan bakar, dan pendapatan terhadap nelayan agen kaitannya dengan perubahan harga solar.

Bycatch tuna is an important commercial fish commodity in the Indian Ocean tuna fishery. Tuna bycatch fishing activity also has an impact on the decline in stocks, making it vulnerable and potentially unsustainable. This study aims to analyze the level of vulnerability of tuna side-caught fish, which was conducted in Sendangbiru Malang in July 2013. Vulnerability analysis using the Euclidean distance approach with productivity and susceptability data using PSA software. The catch of bycacth tuna is skipjack tuna (Katsuwonus pelamis), lemadang fish (Coryphaena hippurus), baby tuna (Thunnus albacores). The results of the vulnerability analysis showed that the level of vulnerability obtained was 1.66 for baby tuna, 1.27 for lemadang and 1.42 for skipjack. Overall, the vulnerability index value is still low from 1.8 where the stock is classified as low susceptibility and the potential for tuna bycatch is still potentially sustainable and does not lead to overfishing.
