A preliminary analysis on the socioeconomic situation of coastal fishing communities in Vietnam

Fish production in Vietnam increased rapidly from 420 000 t in 1981 to 1 130 680 t in 1998. Likewise, there was an expansion in the number of motorized fishing boats from 29 584 units with an average horsepower (HP) of 19.8 boat-1 in 1981 to 71 800 units with an average HP of 26.2 in 1998. In 1995, fish production was valued at VN$2 475 billion (US$0.02 billion at 1 US$ = 11 041 VN$; source: oanda. com).

Preliminary analysis of the dermersal fish assemblages in the Bangladesh waters of the Bay of Bengal

This paper presents the results of analyses of the demersal fish assemblages in Bangladesh waters of the Bay of Bengal. Catch data from three trawl survey cruises from January to February 1985 covering 135 stations were utilized for community structure analysis using TWINSPAN and DCA techniques. Both techniques separated the deepwater stations (> 90 m) from the shallow areas (< 90 m).

Preliminary analysis of demersal fish assemblages in Malaysian waters

Spatial and temporal variations of the demersal fisheries resources of Malaysia were studied using multivariate analysis of their abundance (biomass) from research trawl surveys in relation to geographical and environmental parameters. TWINSPAN results indicate that the demersal resources of Malaysia can be geographically divided into five major species assemblages. Two assemblages are in Peninsular Malaysia and three assemblages are in Sabah and Sarawak waters.

Preliminary analysis of demersal fish assemblages in coastal waters of the Gulf of Thailand

The 1995 trawl data of the research vessels Pramong 2 and 9 in the Gulf of Thailand were analyzed using TWINSPAN and DCA. Four main station clusters were identified related to geographic location and depth. Two clusters are associated with shallow water areas and the other two clusters are found in deeper areas with water depths > 30 m. Temporal analysis indicates clustering of monthly data into wet and dry seasons. Examination of species abundance data indicates that the seasonality may not be very pronounced.

Paralegal work: a community-based approach to fisheries law enforcement ni Negros Occidental, Philippines

The depletion and degradation of the State marine and aquatic resources due to uncontrolled exploitation are the primary reasons for the enactment of fisheries laws. There are two approaches to the enforcement of these laws. Traditional law enforcement involves the intervention or actual performance by government through its designated and deputized agents. However, government activities are directed mainly at preventing further resource depletion. This is a shortcoming that prompted the conduct of alternative law enforcement strategies aimed at resource development.

An overview of the socioeconomic status of fisheries in Malaysia

Fish production in Malaysia increased steadily at 4.5% per annum from 801 000 t in 1985 to 1 280 906 t in 1997. Most of the production was contributed by marine capture fisheries, amounting to 1 168 973 t (91% of total production) in 1997, while the rest (132 700 t or 8%) came from inland fisheries and aquaculture. About 72% of the marine landings, or 837 574 t, were from Peninsular Malaysia while the rest were from the states of Sabah, Sarawak, and the Federal Territory Labuan.

Overview of the national fisheries situation with emphasis on the demersal fisheries off the west coast of Peninsular Malaysia

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).

Molluscicidal compunds of plant origin

There is great impetus among phytochemists to develop molluscicides which are lethal to the snail intermediate hosts of bilharzia. They search for plant-derived, water-soluble compounds that are cheap to isolate, specific to target animals, easily biodegradable, non-toxic to other biota and to which snails are unlikely to become resistant. This paper reports on some medicinal plants from Malawi that have been studied in the hope of isolating compounds for the control of bilharzia.

Marine fisheries along the southwest coast of India

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 forgotten service: food as an ecosystem service from estuarine and coastal zones

In this chapter, we review in detail the existing body of literature and knowledge related to the provision of food in estuaries and coastal zones. Both aquatic and terrestrial commodities are considered. The chapter highlights not only the importance of the terrestrial zone in overall food provision but also the substantial contribution of aquatic coastal resources. The various problems that the coastal zone faces in sustaining this important provisioning service in the face of increasing pressure and demands from other sectors are highlighted.
