Industry in Maldives centers around fishing and tourism with some overlap between the two with recreational fishing. Fishing Pole and line fishing Since time immemorial, the method of fishing employed in the archipelago has been the pole and line method. The types of fish caught by this method are tuna, skipjack tuna, frigate and mackerel. The main catch is tuna, which is used in the daily diet of the inhabitants, as well as for export in different forms. The daily catch depends for the most part on the seasons. Although triangular sailed dhoni were used in the past, today fishing dhoanis are mechanized. Traditionally, the fishermen set out at dawn in search of bait fish, which were caught and kept alive in a specially prepared compartment of the dhoani. Eight or nine men did the actual fishing. The poles are short, are equipped with a line, and hook. During a favorable season, the catch could be as much as a thousand fish per dhoani per day. Traditionally, the fishermen return to the island by nightfall however, with the advent of mechanized dhoani, they are back by early afternoon. Skipjack tuna and yellowfin tuna are the most common species caught in Maldives. Industrial fishing Mechanization of the traditional sailing dhoani in 1974 revolutionized the fisheries industry of the Maldives. A new generation of dhoani, designed especially for mechanization was introduced. A fish-canning factory was set up in 1977 as a joint venture with a Japanese company. However, when the government took over the plant in 1982, it was unable to meet the overseas demand due to the poor condition of buildings and equipment, so a new factory was opened in 1986. In 1979, Maldives Nippon Corporation was formed, in partnership with the Marubeni Corporation of Japan, to process and can fresh tuna. In the same year, the Maldives Fisheries Corporation was formed to exploit fish wealth. (The MFC later became the Fisheries Projects Implementation Department (FPID), which was transformed into MIFCO in 1993). When the Japanese pulled out, the government negotiated a deal to buy the three freezer and six collector vessels that belonged to them, which then became part of the State Trading Organization (STO) fleet. However, by the time that STO inherited the Japanese fleet; the vessels were over twenty years old. A new fleet of vessels was acquired. Three mother ships were built in Korea and nine collector
