Current status of live feed production for larviculture- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

摘要

The major expansion of marine finfish and crustacean aquaculture since 1980s around the world can be attributedudto the development of standard mass production techniques of live feeds. Eventhough most farmed marine animalsudare either carnivorous or omnivorous from their post larval stages, micro algae are required for larval nutrition duringuda brief period either for direct consumption or indirectly as food for live prey fed to small larvae. The hatchery productionudof penaeid shrimp post larvae depends on the use of live diatoms for the early stages and Artemia for later stages. Theudhatchery production of juveniles of marine finfish is achieved globally by the use of rotifers and Artemia. Microalgaeudare also routinely used in the ‘greenwater technique’ employed for marine finfish larviculture.
