Abstract

In order to mitigate impact effects of shrimp culture on the coastal waters environment and improve shrimp culture management, an investigation on the using of biofloc technology in Litopenaeus vannamei culture was carried out in Shrimp research center. Post larva were Stocked with density 250 animals/m²into one pond 40m2, aeration were done continuously, pond was filled with effluent water of shrimp culture, exchange water was zero and treatment of water were done by using different source of carbon such as starch, sucrose and bread. Feeding was done by trash fish and plate food, average amount of salinity and temperature were about 31g/l and 29ºC. After of 72 days culture, harvesting operation was done due to electricity and water aeration problems, Average weight and FCR were computed 13.37g and 1.4, respectively. The results showed that in spite of some physical problems such as the lack of emergency power, water refining during breeding period is possible without any management problem.
