The One

The bluefish, Pomatomus saltatrix, is quite abundant in the Gulf of Gabes, off the south-eastern coast of Tunisia. It is commercially exploited by artisanal gears and trawlers all year round, and by purse seine nets from May to August (bluefish fishery season). Catches of bluefish, in the period 1996–2004 fluctuated between 365.6 t and 1240.1 t with an annual average of 805 t. This fluctuation, partially due to the migratory nature of the species, could be also attributed to the fleet activities that sometimes changed at the mercy of the operators. The analysis of the virtual population of bluefish in the Gulf of Gabes showed that, in 2002, the stock that had just recovered rightly after an excessive fishing in 1996–1997 was again subject to a fishing effort that passed its capacity (E=0.71; E>0.5). The biomass (B) estimated to be ~2178.9 t only tolerated the extraction of 713.4 t (more or less one-third of B). However, the three fleets in use removed 1029.1 t with a yield per recruit (Y/R) of 70.5 g. As a result of this over-fishing, the actual stock of bluefish in the Gulf of Gabes was characterized by individuals having a mean total length of 17.88 cm, a size which is much lower than the one at first sexual maturity (23.5 cm). The turnover (D/B) being of 75.23%, it did not allow the reconstitution of the stock. The total removals (~1639 t) due to both natural mortality (M=0.28) and fishing mortality (F=0.675) had to be compensated especially by individual growth (1534.2 t; 93.6%) because of the low weight of the recruits.

Illegal fishing carried out by foreign fishing vessels (Kapal Ikan Asing, KIA) and Indonesian fishing vessels (Kapal Ikan Indonesia, KII) in Indonesian waters also causes other crimes such as the entry of illegal immigrants to Indonesia. This writing aims to assess the relationship between illegal fishing and the entry of illegal immigrants as a form of transnational crime. The research method used is normative legal research. The sources of legal material used are primary, secondary and tertiary legal materials related to writing. The technique of collecting data through library studies and analyzed qualitatively. The results of the study show that Indonesia as the largest archipelagic country in the world with 17,504 large and small islands and a length of coastline of 81,700 km 2 makes Indonesia a country with abundant marine resource potential. For this reason, many foreign naval fleets have made Indonesian waters as the main destination for their capture fisheries. This capture fishery company has more foreign ownership, the exploitation of marine resources that we own both legally and illegally. Likewise, this also happened in the Moluccas territory. As a province of the archipelago with an ocean area of ​​658,295 km 2 with a coastline length of 11,000 km 2, the Maluku Sea holds abundant potential for marine wealth. Arafura Sea is one of the fisheries management areas which is often the main destination for foreign-owned fishing vessels. These fresh fish from the Moluccas are stolen and taken away in fresh condition directly to the area of ​​origin of the perpetrators. Illegal fishing activities not only make Indonesia economically disadvantaged, but there is another problem, namely the existence of other crimes that usually follow the illegal fishing activities. One of them is the entry of illegal immigrants into Indonesian territory.

Research on the growth and exploitation status of indian catfish (Plotosus canius) is important in supporting the management of fish resources in the waters of Tanjungpinang City, Riau Islands. The study aims to determine the pattern of growth, growth parameters, and the status of indian catfish exploitation in the waters of Tanjungpinang City, Riau Islands Province. The study was conducted with a purposive sampling method of 3 stations with a total sample of 529 individual fish crosses. Analysis of growth and exploitation status data using FISAT II software and regression analysis using Excel 2017. This study resulted in a pattern of long relations and the weight of fish as a female and males both are negative allometric (faster increase in length than weight increase). The highest rate of exploitation of indian catfish is obtained from the data of 0.73 per year. This exploit value exceeds the optimum exploitation value of 0.5.

Indonesia memegang peranan penting dalam perikanan Tuna, Tongkol dan Cakalang di dunia. Indonesia telah memasok lebih dari 16% produksi Tuna, Tongkol dan cakalang dunia. Tuna dan cakalang memiliki peranan penting bagi sektor perikanan tangkap di Indonesia sehingga pengetahuan tentang profil perikanan Tuna dan cakalang menjadi sangat penting untuk diketahui. Kajian yang dilakukan pada tahun 2017 ini bertujuan untuk mendeskripsikan profil perikanan Tuna dan cakalang di Indonesia yang akan dikemukakan berdasarkan penelurusan data sekunder berupa data statistik, laporan penelitian dan publikasi ilmiah terkait perikanan Tuna dan cakalang di Indonesia yang dianalisis secara deskriptif. Hasil kajian menunjukkan bahwa perikanan Tuna dan cakalang di Indonesia terdiri jenis yaitu industri dan artisanal. Daerah penyebaran ikan Tuna dan  cakalang meliputi  Laut Banda, Laut Maluku, Laut Flores, Laut Sulawesi, Laut Hindia, Laut Halmahera, perairan utara Aceh, barat Sumatera, selatan Jawa, utara Sulawesi, Teluk Tomini,  Teluk  Cendrawasih  dan  Laut  Arafura. Produksi Tuna dan cakalang terus meningkat sejak tahun 2000 sampai dengan tahun 2015. Peningkatan produksi Tuna dan cakalang menunjukkan bahwa tingginya tingkat permintaan terhadap kedua komoditas tersebut. Alat tangkap yang digunakan untuk menangkap Tuna dan cakalang sangat beragam yang dapat dikelompokkan menjadi 6 jenis, yaitu rawai Tuna (Tuna long line), rawai hanyut selain rawai Tuna (drift longline other than Tuna long line), rawai tetap (set long line), huhate (skipjack pole and line), pancing tonda (troll line) dan pancing yang lain (other pole and line)Title: The Profile of Tuna and Cakalang Fishery in IndonesiaIndonesia plays an important role in Tuna and Skipjack fisheries in the world due to its supply of  more than 16% of the world’s Tuna and skipjack production. Since they have been being a vital commodity in capture fisheries in Indonesia, it is important to have knowledge of Tuna and skipjack fisheries. This study was conducted in 2017 and it aims to describe the profile of Tuna and skipjack in Indonesia that built upon secondary data. The data were collected from statistical data, scientific report and publication related to Tuna and skipjack fisheries in Indonesia and they were analyzed using descriptive method. The results suggest that Tuna and skipjack fisheries in Indonesia consist of industrial and artisanal types. The fishing ground of Tuna and skipjack covering Banda Sea, Maluku Sea, Flores Sea, Sulawesi Sea, Indian Ocean, Halmahera Sea, Northern Aceh Sea, West Sumatra, South Java, North Sulawesi, Tomini Bay, Cendrawasih Bay and Arafura Sea. The production of Tuna and skipjack Tuna continues to increase particularly during 2000 to 2015. The increased number of Tuna and skipjack production indicates the high demand of these two commodities. There are various fishing gear to catch Tuna and Skipjack, which can be grouped into 6 types, namely Tuna long line, drift longline other than Tuna long line, set long line, huhate (skipjack pole and line), troll line and other fishing rods (other pole and line)

Red snapper resources in the Arafura Sea have been effectively exploited by the industrial scale of bottom long line, fish trawl and shrimp trawl fisheries. Research activities carried out by the ACIAR-RCCF revealed that there were genetic similarity of the three red snapper species between the Australian and lndonesian sectors of the Arafura Sea"
