Nutrient removal from shrimp farm effluent by aquatic plants.
Duckweed was used to treat effluent from a shrimp farm in a batch wise and recirculation system. The result showed that duckweed could efficiently remove nutrients in the effluent, especially ammonia, which seemed to be the preferred nitrogen source of the plant. Red tilapia was used in the recirculation system and showed high potential in removal of uneaten shrimp feed.
