Abstract
The survival rate of mud crab or mangrove crab Scylla serrata larvae was evaluated using black and yellow-painted tanks. About 400,000 zoea 1 were stocked in 6 tons of treated seawater. The larvae were initially fed with rotifers and subsequently with newly hatched Artemia until the megalopa stage. The larval rearing water was enriched with a combination of Spirulina powder and frozen micro-algal products that include Nannochloropsis sp., Tetraselmis sp. and Thallasiosira weissfolgii. After 15 to 17 days of rearing, the larvae successfully molted to megalopa stage. A total of 377,062 megalopae were harvested. Although the survival rate of megalopae was higher in yellow tanks (23.63± 0.03%), it was not significantly different when compared to those in black tanks (15.66±0.02%) (P=0.05).
