    Trawl fisheries are an important component of the capture fisheries sector in Malaysia. Although small in terms of percentage of licenses issued (11.79%), their significance is underlined by their contribution to the overall landings (48.19%), as shown in the table below for the year 2011.

    The trawl catch is showing an increasing trend all along Indian coast, which is contributing highly to the economy of the country. Research programs are being conducted for resources conservation and sustainability of production in trawl fisheries. The changes in fishing technology and catch characteristics, like pelagic trawl introduction, introduction of high speed engines, bycatch issues and juvenile fishery are monitored and discussed in various forums organized by government of India. Such awareness and participatory programs are also yielding socially acceptable solutions for many of the issues. The closure of fishery during monsoon is earnestly followed by the trawl fishery. The debate is going on for introduction of new ban period and/ extension of existing ban period in various fora.

    The trawl Fisheries of the western Bay of Bengal 2013

    The Western Bay of Bengal (WBoB) trawl fishery is typically a tropical multispecies mixed fishery with a history of commercial exploitation since early 1960s. The nature of fishing changed dramatically with the introduction of trawlers. In the last 50 years, trawlers have become immensely popular and have emerged as the most important fishing craft in the region. The trawl fishery extends from 8oN (off Kanyakumari on the south) to 22oN (off Sunderbans in the north), accessing fishing grounds bet ween 10 m and 150 m depth, but often restricted to a maximum depth of about 70 m. Thus trawling by Indian fishermen has remained exclusively a coastal activity and deep-­‐sea trawling is occasional. The main gear is the bottom otter trawl, with two variants, namely the shrimp trawl and fish trawl. The difference between the two variants is that the shrimp trawl scrapes through the bottom with more sinkers, and the fish trawl is hauled slightly off bottom with more floats. The fishery is complex with operation from craft varying in length and efficiency. All trawlers are mechanized, with the engine placed inboard. Being multispecies, the fishery exploits species that widely vary in their life history traits and habitats. Approximately 800 species of elasmobranchs, teleosts, crustaceans, molluscs and echinoderms are taken by the trawls, and at least 300 species contribute to the fishery.
