Impact of shrimp aquaculture on hydro biological parameters of Kali estuary, Karwar, West Coast of India

Abstract

The present study was carried out to determine the impact of shrimp aquaculture on hydro biological parameters of Kali estuary, West Coast of India, from 2016 to February 2017. The water parameters were studied and the result showed an increase in nutrients in the Shrimp culture area. Low level of Dissolved oxygen was also seen in the Shrimp culture area indicating some stress on the estuarine ecosystem. From the present study it is understood that aquaculture activities and the release of pond water into the estuarine body will have some impact on the water quality near the pond activities, which if left as it is, will also have an impact on the biotic and abiotic component in the future.
