Abstract

Water Quality in aquaculture encompasses all physical, chemical and biological variables that affect aquaculture production. The aquatic environment is a c6mplex dynamic system. It is subject to constant physicochemical changes due to natural causes and man's activities. The slightest deviation from the optimal level may result in stress to the cultured organisms. Stress elicits a series of physiological and behavioral responses in the organisms.If prolonged, the stress may lead to poor growth, reproductive failures besides rendering them susceptible to diseases. Most pond management procedures are aimed at improving the water quality.
