WorldFish is an international, nonprofit research organization that harnesses the potential of fisheries and aquaculture to reduce hunger and poverty. Our publications database contains WorldFish publications and references to WorldFish research published in refereed journals and periodicals.
The objectives of the workshop were designed to place emphasis on applications. It was perceived that the fisheries are at present so intense and the available information so limited, that a special effort should be made to develop from present understandings a set of tools for rough and ready action, now. Awaiting the development of much more sophisticated under¬standing before making commitments to particular approaches was not seen as a prudent course of action.
The maximum sustainable yield of demersal fishery resources in the Gulf of Thailand to a depth of 50 m is estimated to be 750,000 tonnes. On this basis the Gulf has been overfished since 1973. There were over 4,000 trawlers registered in the Gulf in 1972; over 10,000 in 1982. The total catch of food fish has increased only slightly since 1963, most increases being of trash fish. However, the trash fish component includes increasing numbers of juvenile food fish.
Fishing installations consisting of branches of trees, bushes or other soft vegetation stuck into the muddy bottoms of lagoons, lakes or rivers, are common throughout the world. Collectively, these may be termed "brush parks" and are found in many parts of west Africa, Madagascar, Sri Lanka, Bangladesh, Cambodia and China, as well as in Ecuador and Mexico.
