THE USE OF CHEMICAL AND BIOLOGICAL PRODUCTS IN SHRIMP FARMS AND HATCHERIES

A large number of chemical and biological products are used in the management of shrimp hatcheries and shrimp farms. The information presented here is based on interviews performed at 50 hatcheries and more than 70 shrimp farms in a country that is a major producer of shrimp in southeast Asia. The products used in shrimp hatcheries and in management of shrimp farms include fertilisers, disinfectants and pesticides, antibiotics, micro-organisms, immunostimulants, and feed. Observed trends are, for example, that fluoroquinolones have become the most commonly used group of antibiotics in shrimp farm management, while nitrofurans and tetracyclines are the most common in hatcheries. The use of heavy metal based pesticides seems to have decreased, while certain organophosphates are fairly commonly used in shrimp farms. The nitroaniline compound trifluralin is used both in shrimp farms and hatcheries. Use of micro-organisms has become very common in shrimp farm management, but is less often used in hatcheries. The material is discussed with respect to risks for adjacent ecosystems and human health.
