Physiology in aquaculture with special reference to penaeid shrimp aquaculture- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

摘要

Aquaculture has been practiced in some societies for many centuries. However, the transition from low-input,udpond-based capture system to more intensive and industrialized method has been done only during the last fewuddecades. Contrary to terrestrial agriculture systems, aquaculture is a new industry with limited scientific knowledge.udThis is especially true for shrimp aquaculture, the fast growing and most valued food production systems of the world.udShrimp aquaculture has been developed without sufficient understanding of basic physiology of species of interest.udPhysiology is a powerful science, which has potential to contribute positively for the development and growth ofudaquaculture. The more understanding of the physiological processes that underlie crop performance leads to theudimprovement and optimization of aquaculture production. Further, as knowledge of physiological process expands,uddesirable traits can be identified, and that can be utilized as selection criteria. Incorporation of physiological traits forudselection in breeding programme, thus, would help to achieve results more quickly and efficiently than selecting forudyield performance alone. This lecture note provides an overview of various aspects of reproductive physiology thatudhave direct application in optimizing aquaculture production. The possibilities of selecting physiological traits in breedingudprogramme have also been discussed.
