Condition Factor, Hepato-somatic Index and Gonado-somatic Index of Fish, Channa punctatus Collected from Sawan Nallaha, Balrampur, U.P.

Abstract

Biomarkers are measurements within an organism that respond to environmental changes and are used as bio-monitoring tools that reflect physiological changes induced by exposure to pollutants. The condition factor (K), hepatosomatic index (HSI) and gonado-somatic index (GSI)of fish, Channa punctatus was used to assess the effects of industrial pollutant stress. For this study, Channa punctatus was collected from Sawan Nallaha, a small lotic waterbody in all the seasons (Summer, monsoon and Winter). Fish collected from the non-polluted site had the higher condition factor (K) HSI and GSI as compared to fish collected from polluted site
that received the industrial effluent and domestic sewage. K, HSI and GSI are simple and costeffectivebio-monitoring tool and can be used in pollution monitoring.
