The article presents the current state of mangroves in Southeast Asia. In several countries lost mangrove areas were due to the conversion of mangrove forest into aquaculture and other uses. The ecological and socioeconomic effects of mangrove destruction are also presented.

The article presents about mangroves and its value to the ecosystem. The different species in the Philippines and mangroves coping mechanisms to the environment are also presented.

The paper presents some recommendations for the development of the environmentally acceptable coastal aquaculture such as: 1) Formulate coastal aquaculture development and management plans, 2) Formulate integrated coastal zone management plans, 3) Apply the environmental impact assessment(EIA) process to all major aquaculture proposals, 4) Select suitable sites for coastal aquaculture, 5) Improve the management of aquaculture operations, 6) Assess the capacity of the ecosystem to sustain aquaculture development with minimal ecological change, 7) Establish guidelines governing the use of mangrove wetland for coastal aquaculture, 8) Establish guidelines for the use of bioactive compounds in aquaculture, 9) Assess and evaluate the true consequences of transfers and introductions of exotic organisms, 10) Regulate discharges from land-based aquaculture through the enforcement of effluent standards, 11) Establish control measures for aquaculture products, 12) Increase public awareness of the safety aspects of consuming seafood, 13) Apply incentives and deterrents to reduce environmental degradation from aquaculture activities, and 14). Monitor for ecological change.

The article presents environment friendly aquaculture practices such as semi-intensive aquaculture, the culture of native species, the selection of proper sites for aquaculture facilities, the conduct of thorough, honest socioeconomic and ecological impact assessment before proceeding with the implementation, and the practice and promotion of proper pond/cage/tank preparation and management among others.

The inadequate planning and inefficient management of coastal aquaculture has resulted into serious socioeconomic consequences. These are the displacement of rural communities which traditionally depended on mangroves due to large-scale mangrove conversion for shrimp and fish farming, land subsidence caused by excessive pumping of groundwater for use in aquaculture, financial losses due to disease outbreaks, and public health consequences due to red tide. In order to maximize the socioeconomic benefits of coastal aquaculture the adoption of the principles of sustainable development id recommended. Sustainable development is the management and conservation of natural resource base and the orientation of technological and institutional change in such a manner to ensure the attainment and continued satisfaction of human needs for present and future generations.

The study presents the type and scale of any ecological change associated with coastal aquaculture development. These are enrichment, interaction with the food web, oxygen consumption, disturbance of wildlife and habitat destruction, interaction between escaped farmed stock and wild species, introduction and transfers, bioactive compounds (including pesticides and antibiotics), chemicals introduced via construction materials, and hormones and growth promoters.

The article presents two common sources of fish leather, these are shark and barramundi. The processing and market acceptance of the products are also discussed.

The article presents new food processing equipment for coating and frying. These are predusters, liquid enrobers and applicators for large-particle crumbs.

The article discusses the potential for export of value-added shrimp products from developing countries. European Economic Community is considered to be one of the top consumers, while Thailand and India are two of the top producers.
