Hundreds of fish found dead at Kukkarahalli lake
Remains of about 150-200 large fish removed from water body
When contacted by Deccan Herald, Assistant Horticulture Officer of University of Mysore, the custodian of the lake, S K Mujavar said that ‘carcass of fish were found floating on Sunday morning. They were cleared using two coracles with the help of Karnataka State Cooperative Fisheries Federation. About 150-200 large fish were removed during the operation’.
Convener of Kukkarahalli Lake Protection Committee, K M Jayaramaiah attributed the fish kill due to a reduction in dissolved oxygen levels near the banks of the lake, owing to the flow of sewage from Paduvarahalli side. “Such fish kills occur when dissolved oxygen level dips below 3 milligram per litre of water. Fish require 5-6 milligram per litre of the same to survive,” he said.
He added that works taken up to divert the flow of sewage into the lake to a sewage treatment plant is expected to be completed in the course of the next month and half, after which such problems will not be repeated, he said.
A similar incident was witnessed during November 2014, where dead fish were fished out from the lake for three days, after a microcystin bloom, which was also attributed to sewage flow, claimed their lives.
