Bangladesh. Once the megalopa was obtained they were carefully separated andtransferred to 100-L plastic tank and small PVC pipe cuttings were placed allover the tank bottom for attachment and refuge. The crablets were fed withminced fresh marine squid.Fig. 1. Hatched eggs to crablet stages under the captive breeding of mud crab.The most important requirement for mud crab breeding is clean seawater. Itis therefore essential to provide facility for water treatment in the hatcherydepending on the quality of source water. Aside from improving live feed qualityto meet all nutritional requirements of the larvae, the biggest challenge for crablarval rearing will probably be the development of safe and sustainableprophylactic treatments to prevent microbial interactions. Although severalissues still need to be solved, it may conclude that knowledge of mud crabbreeding and larval rearing techniques have, in recent years, evolved to a levelcomparable to that of shrimp in the early nineties, and therefore commercialapplication might be envisaged within a few year time in the country.Acknowledgement: The authors wishes to acknowledge Aquaculture for Incomeand Nutrition (AIN) Project under USAID, WorldFish, Bangladesh and MarineFisheries & Technology Station, BFRI for providing technical and financialsupport.
