This study compares water quality from different intensive shrimp production systems; high water exchange, low water exchange, zero water exchange and lined ponds; at different stages of the culture cycle. Reducing water exchange is one method employed by shrimp farmers to try and reduce incidence of viral disease on shrimp farms, however this can lead to stressful build-ups of nitrogenous compounds especially ammonia in the water. There is a need for further development of management strategies to allow the maintenance of a healthy rearing environment whilst reducing effluent impact.
