Abstract
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.

Summary
Potensi sumberdaya perikanan di Indonesia sebesar 9,931 juta ton per tahun, dengan potensi tertinggi terdapat di WPP 718 sebesar 1,992 juta ton/tahun (20%), di WPP 572 sebesar 1,228 juta/tahun (12 %) dan di WPP 711 sebesar 1,143 juta ton/tahun (12 %). Bigeye Tuna (Thunnus obesus) menjadi salah satu komoditas unggulan dari sub sektor perikanan yang umum dikonsumsi baik skala lokal maupun ekspor. Pelabuhan Perikanan Samudera (PPS) Cilacap, Kabupaten Cilacap, merupakan salah satu pendaratan ikan Bigeye Tuna (Thunnus obesus) yang ditangkap dari Samudera Hindia. Penelitian ini bertujuan untuk mengetahui informasi hubungan panjang bobot Bigeye Tuna (Thunnus obesus) yang ditangkap dari Samudera Hindia dan didarat di PPS Cilacap, Jawa Tengah. Sebaran frekuensi panjang tertinggi Bigeye Tuna (Thunnus obesus) yang tertangkap berada disebaran panjang 123,5 – 156,5 cm. Hasil anlisis hubungan anjang bobot diperoleh kesimpulan bahwa pola pertumbuhan ikan Bigeye Tuna (Thunnus obesus) adalah allometrik negative (b< 3). Hubungan panjang bobot ikan ini merupakan salah satu informasi yang perlu diketahui dalam kaitan pengelolaan sumberdaya perikanan
