Valuation of coral reef systems: case study of Philippine coral reefs (Taklong Island national marine reserve)

This report is an outcome of a collaborative effort between ICLARM and the University of Philippines - Visayas with funding support from Sida under the project "Valuation and policy analysis for sustainable management of coral reefs". The report summarizes various outputs provided by Taklong Island National Marine Reserve( TINMAR) that directly benefit the coastal communities and other resource users. The biological studies reviewed in the report also indicated that fish biomass has increased which can be attributed to the protection of the area as a marine reserve.

The use of wild-caught juveniles in coastal aquaculture and its application to coral reef fishes

Worldwide, there are many substantial coastal aquaculture and stock enhancement operations based on collection of wild juveniles. These include: growout of shrimp (Penaeidae), milkfish (Chanos chanos), eels (Anguilla spp.), yellowtail (Seriola quinqueradiata), southern bluefin tuna (Thunnus maccoyii), edible oysters (Ostreidae) and mussels (Mytilidae); stock enhancement of scallops (Pectinidae); and the culture of pearls in farmed blacklip pearl oysters (Pinctada margaritifera). The growout of wild puerulus larvae of spiny lobsters (Palinuridae) is also developing rapidly.

The use of antibiotics in aquaculture: health and environmental issues, control and mitigation measures

This paper attempts to review the use of antibiotics in aquaculture in Malaysia because of the heightened concerns over its use and abuse and its impact on human health and the environment. Health and environmental issues relating to antibiotic use and measures that can reduce or control the impacts are also discussed.

Understanding livelihoods dependent on inland fisheries in Bangladesh and Southeast Asia: Vietnam summary report

This is one of the four countries reports which provides an assessment of the livelihoods strategies of the poor people dependent on inland fisheries in Vietnam. The project aimed to characterise the poor, identify their dependence upon aquatic resources, the nature and status of those resources, and their vulnerabilities in relation to loss or mismanagement. Constraints and possible research priorities have been identified through consultations with poor fishers and other aquatic resource users, and with other organizations. Fisheries resource status has been summarized.

Understanding livelihoods dependent on inland fisheries in Bangladesh and Southeast Asia: synthesis report

This report provides an assessment of the livelihoods strategies of the poor people dependent on inland fisheries in Bangladesh, Cambodia, the Lao PDR and Vietnam. Drawing upon the results of a one year investigation under the Project entitled "Understanding Livelihoods Dependent on Inland Fisheries", policies and institutions for fisheries management and livelihoods assets of the stakeholders in inland fisheries in the four countries. The report also discusses the trends and changes in fisheries and wetland resources.

Understanding adoption and discontinuance for greater impact

Floodplains are characterized by a period of several months when the land is not available for agriculture and large, open areas are used for fisheries. The enclosed part of these flooded areas can be utilized for fish production aside from naturally occurring self recruited species through a community-based management system. Experiences in the Vietnamese and Cambodian Mekong Delta and Ganges Delta in Bangladesh between 2006 and 2009 highlighted the potential of this model and its limitations.

Tropical man-made lakes, African fish and cheap protein

Tropical reservoirs (man-made lakes) have evened out somewhat the distribution of standing waters on a global scale. Natural lakes are well represented in the North Temperate and Arctic regions. In the tropics, the only region with a sizeable lake area is the rift valley region of East Africa. Man's reservoir building activities have created the potential for a rich source of cheap fish protein. This potential is best realized when lacustrine tilapias from Africa are present.

Transgene expressions in seabass (Lates calcarifer) following muscular injection of plasmid DNA: a strategy for vaccine development?

Muscular injection has become one of the direct methods for transferring foreign DNA into organisms. The technique has been recently introduced in the development of vaccines and gene therapy. Vaccine development, in particular, would be desirable in managing viral diseases in farmed fish. In this study, the technique was performed on seabass (Lates calcarifer) and was found that the foreign gene could be transferred successfully through injection into the muscles.
