Transport of sugpo, Penaeus monodon juveniles

This study was made as an attempt to investigate the optimum packing density and the ice quantity suitable for the transport of Penaeus monodon juveniles. The results revealed that prawns of 40 mg size can be packed to as much as 3,000 per bag. While packing densities above 3,000 per bag containing 8 L seawater and 16 L oxygen can be used only for short transport periods. On the other hand in the ice-quantity experiment, mortality rate was less than 1% in all the bags containing 300 g, 600 g, 900 g and 1200 g of ice. A packing temperature of 20~’C must be maintained hence, 50 g of ice per hour should be allowed per box, counting from the moment the box is sealed to the time it is estimated to be opened.

Adopt sustainable development principle in aquaculture

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 is 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.
