Water Quality Of Shrimp Pond Water During Harvesting
Shrimp farming is an important source of revenue for Sarawak. Shrimp farms are usually located at the estuary utilizing brackish water for the growth of shrimps. Due to the excess fE~ed and feces accumulation over the culture period, pond water had to be drained and the pond bottom cleaned during ha...
