Relative biomass per recruit of adult (i.e. sexually mature) fin to shellfish is shown to help in identifying levels of fishing mortality likely to lead to recruitment overfishing. This is illustrated with data from a Malaysian penaeid shrimp fishery.
The marine fisheries sector in Malaysia contributes significantly to the national economy in terms of income, foreign exchange and employment. In 1999, marine fisheries contributed 1.245 million t (90% of total fish production) valued at US$1.18 billion. The total value accounted for about 1.53% of national GDP and 11.31% of agricultural GDP. The export of fish and fishery products amounted to about US$210 million. The sector provided employment to about 80 000 fishers. Fisheries management is currently guided by the Third National Agricultural Policy (NAP3 1998 - 2010).
An account is given of fisheries in Haiti which employ primitive technology, and problems regarding overfishingconsidered. Since boats used are small and motorless, there is no fishing activity in deep water and Haiti has to import fish to supply the needs of the people. Possibilities in aquaculture and also regulation and expansion of themarine fishery are examined.
The worldwide depletion of major fish stocks through intensive industrial fishing is thought to have profoundly altered the trophic structure of marine ecosystems. Here we assess changes in the trophic structure of the English Channel marine ecosystem using a 90-year time-series (1920–2010) of commercial fishery landings. Our analysis was based on estimates of the mean trophic level (mTL) of annual landings and the Fishing-in-Balance index (FiB).
Major factors that have contributed to the failure in Jamaica to implement fisheries management successfully are examined. Problems in the management expertise and infrastructure are detailed.
Marine fisheries production in India has increased from 0.5 million t in 1950 to 2.47 million t in 1997. The gross value of fisheries landings in India was US$2.37 billion in 1997. The contribution of fisheries to the Gross Domestic Product (GDP) has risen from 0.7% in 1980 - 81 to 1.2% in 1994 - 95. The contribution to agricultural GDP has risen from 1.9% to 4%. Fisheries production also plays a critical role in food security and livelihood in rural areas.
The fisheries sector of Vietnam plays an important role in the social and economic development of the country. The sector contributes about 3% of the GDP and fish contributes about 40% of animal protein consumption in the country. In 1999, total fisheries production amounted to 1.8 million t. Of this, 1.2 million t was derived from marine capture fisheries and 0.6 million t from aquaculture. Fish exports were valued at US$971.12 million in the same year. Vietnam’s marine fisheries and coastal aquaculture have further potential for development.
An examination was made of data on the length and species composition of the commercial deepsea snapper fishery of the Kingdom of Tonga in order to determine possible use of such information in the determination ofstatus of exploitation. Six major species were used for the analysis--Pristipomoides filamentosus, Etelis coruscans, P. flavipinnis, E. carbunculus, Epinephelus morrhua and E. septembasciatus . Although catch and effort data do not indicate overexploitation of the fishery, the size differences observed for P.
This paper discusses fisheries management reforms through involving local level institutions (LLFI). It is based on studies which were undertaken on Tanzania’s Lake Victoria fishery where LLFIs were established through the formation of Local enforcement Units, later named Beach Management Units (BMU), between 1998 and 2002. The paper takes the view that the overfishing problems that confront Tanzania’s fisheries management authorities are best understood from a social science perspective. The argument is that most communities’ values and institutions are embedded in their societies.
