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.

The Relationship

The cAja-’ib al-Hind ( Marvels of India) is a collection of sea stories allegedly compiled by Captain Buzurg Ibn Shahriya-r (d. 399/1009) which belongs to an Arabo-Islamic literary genre called the caja-’ib, containing themes of entertainment—things that are marvellous and strange. But these stories are not merely entertaining, they are an additional resource for the modern researcher because they also reflect the realities of daily life in seafaring communities of the Indian Ocean in the ninth and tenth centuries. Among the tales of the fantastic and the marvel, we find the simple humanity of the seafarers, something lacking in the purely factual, medieval, geographical and historical texts. A complementary model to the understanding of the maritime landscape of a group or community is proposed in this article. The stories model in this article demonstrates the relationship of an occupational group with other seafarers in a trans-regional Indian Ocean trade.

Bigeye tuna is an important fish resource in the Indian Ocean. This species like other tuna species needs to be managed properly in both national and international levels. Therefore some data and information on population structure and bioreproduction are required for management purpose. The current research was conducted to identify the population structure and bioreproduction of bigeye tuna (<em>Thunnus obesus</em>) in west off Sumatera and south off Java and Nusa Tenggara of Indian Ocean where tuna fishing spots are important. This research was based on catch landed by fishermen from the Indian Ocean during 2010. Analysis of population structure was done using DNA genetic analyses and bioreproduction by using histology technique. Results show that the population structure of the bigeye tuna in the Indian Ocean consisted of two different sub populations namely sub population of west off Sumatra and sub population of south of Java and Nusa Tenggara waters. Most of catch (about 39%) was categorized as immature fish (GI I). The immature fish was mostly found in west off Sumatera waters, meanwhile the catch in south off Java and Nusa Tenggara waters was mostly categorized as mature fish. This result may indicate that south off Java and Nusa Tenggara waters is a spawning ground of the bigeye tuna.
