KOCHI: The excessive growth of oscillatoria, a toxic algal bloom, is behind the fish kill in the Sri Krishna temple pond at Ambalappuzha, according to a team of scientists from Kerala University of Fisheries and Ocean Studies (KUFOS).
The dissolved oxygen (DO) content in the water went down following the uncontrolled growth of the algal blooms. The water analysis test conducted by the experts revealed that 1,30, 000 oscillatoria were found in one millilitre water.
“Excess of nutrient content and the lack of water circulation resulted in the growth of the algal blooms. The osciallatoria is highly toxic,” the experts said. The water inside the pond needed to be flushed out and new water filled to control the issue, they suggested.
Dr Swapna P. Antony, Dr Linoy Libini and Dr Binu Varghese from the School of Aquaculture and Biotechnology of KUFOS visited the spot. Fisheries Deputy Director S. Mahesh was also present.
