Fish dead in Katraj lake, PMC blames it on hyacinth
"Water hyacinth does not grow all of a sudden," Yadwadkar said, adding it was the responsibility of PMC to remove it but they failed to do so.
PMC environment officer Mangesh Dighe said the administration will send water samples for lab tests to ascertain oxygen content. "If large number of fish died in a small span of time, it needs to be investigated properly. We will also approach the state fisheries department to find the reasons," he added.
