Abstract

Chaetoceros calcitrans is a marine diatom widely used in aquaculture industries, as it is comprised of nutritional value suitable for most marine filter feeders. Large amounts of the diatom cells are routinely discharged from shrimp hatcheries as uneaten food. The effluent, rich in algal cells, can potentially be re-used to feed oyster broodstock, as the oysters are an effective filter feeder. This study attempted to investigate viability of C. calcitrans as a monospecies diet for conditioning broodstock of Crassostrea belcheri. It was found that gametes of both sexes developed to spawning condition when rearing in captivity using C. calcitrans. Gametes were found in all four stages i.e. active, ripe, spawned and spent - at 15.4, 30.8, 30.8 and 23.1%, respectively when reared for 20 days. When the conditioning period was extended for 40 days, the development stages were found at 15.4, 15.4, 30.8 and 38.5%, respectively. The whole body weight decreased 2.01-2.65% after 20 days and 7.72% after 40 days. The condition indices were obtained between 6.31-7.78% and showed no relation to gametogenic stages of gonad. This study concluded that C. calcitrans can potentially be used as a monospecies diet for conditioning of oysters C. belcheri broodstock.
