Author(s): Krishna PV, V Panchakshari, P Suresh, K Prabhavathi and K Anil Kumar

Abstract: In Andhra Pradesh lake Kolleru has been recognized as wet land of International significance and a Ramsar site. The wet lands are very important productive ecosystem and socioeconomic values are well established. Anthropogenic pressure such as large scale encroachment of lake bed for aqua farms, high level use of fertilizers, pesticides, fish/prawn waste discharges, domestic wastes and sewage from three municipalities and discharge of industrial effluents and agriculture run-off have vitally effected and altered the ecological character. Due to continuously increasing natural and anthropogenic stresses, now days this entire species community focus a tremendous problem of survival. The results present study revealed that the occurrence of 14 species belongs to 9 genera and 6 families order siluriformis and family bargidae is dominant group followed by siluridae and ariidae. Out of 14 species percentage of various threat category as per IUCN, 64% were least concern, 22% were near threatened, and 14% were endangered. As per CAMP, 43% were not evaluated, 22% were vulnerable, 14% of both endangered and least concern, and also 7% were least concern. The biodiversity index also discussed in the season wise.
