Hundreds of fish found dead in Bengaluru's Ulsoor Lake

Senior civic officials say such fish kill is almost an annual occurence with rising temperatures.

A large fish kill was reported in the Ulsoor Lake on Monday morning. Hundreds of fish were found dead and floating in the morning and washed ashore later in the day.

Senior Bruhat Bengaluru Mahanagara Palike (BBMP) officials said that this was almost an annual occurrence with rising temperatures.

“Fish kill is usually a direct result of reduced dissolved oxygen level in the water. While algae in the lake release oxygen into the water, it uses up dissolved oxygen during night time along with the fish, creating a big drop in the dissolved oxygen levels. So most fish kills are observed in early mornings,” an official said
