Descripción
For decades, fish farmers in Asia and the Pacific region obtained their supply of fish seed from natural sources. In most areas, the availability of seeds from these waters has become scarce. The supply has shown a marked decline which cannot meet the demand of expanding fish culture. The rapid development of aquaculture in the region has required the establishment of fish hatcheries for the mass production of fry. Hatchery operations have been activated in order to produce adequate fry to suppo rt the needs of fish farmers. There are presently in operation many commercial and experimental hatcheries in the region. Larval rearing of finfish, shrimps and prawns, and shellfish in hatcherie entails the culture of food organisms to assure the favourable growth and survival of the young. The culture of certain plankton species for feeding milkfish fry and penaeid post-larvae, for instance, has been practiced in several Asian countries. In hatchery operations, the use of certain-kinds of pl ankton as food is important. Hatcheries utilize artificially grown food organisms in their larval rearing.
