Abstract
The aim of this study is to document the current status on the use of antibiotics, chemicals and biological products used in shrimp hatcheries and grow-out ponds in Bangladesh. In the last decade, coastal aquaculture practised traditionally in south western and south eastern parts of Bangladesh has developed into a big industry. With the rapid expansion of shrimp grow-out facilities, the hatchery industry has progressed rapidly during the last five years. A major disease outbreak, namely white spot disease in 1995 struck the shrimp aquaculture throughout the country and resulted in increased use of chemotherapeutics for disinfection and treatment. Among the 50 operating hatcheries of Bangladesh, 40 (80%) were surveyed in which 7 different antibiotics, 6 disinfectants and 2 different biological products were used for controlling common diseases. The study also covered 50 grow-out ponds of which 30 were in southwestern and 20 were in southeastern part of Bangladesh. The study included 8 semi-intensive and 42 extensive farms. Diseases were treated with 15 commercial products belonging to 3 antibiotics classes. The antibiotics currently used in shrimp aquaculture in Bangladesh are chloramphenicol in the name of CL-33, prefuran, oxytetracycline, furazolidone, erythromycin, neomycin sulphate, kenamycin sulphate and ciprofloxacin.
