39-Comparison of source, pond and discharge water during Shrimp culture along Udupi and Dakshina Kannada Districts of Karnataka State

Abstract

Productivity of a fish pond depends largely on the abundance of fish food organisms and also on occurrence of congenial environmental conditions in the pond. Presence of nutrients in adequate amounts in pond water is essential for successful aquaculture. The stress induced by poor water quality may result in reduced growth rates. Studies are carried out to compare the properties of source, pond and discharge water during shrimp culture along Udupi and Dakshina Kannada districts of Karnataka state. Water samples were collected and various parameters were measured. The results of water analysis from the source, culture ponds and discharge channels during culture showed an increase in values of most of the water quality parameters in the ponds and discharge channel as compared to intake water. All the water quality parameters were within the permissible range.
