A large number of fish were found dead in the moat of the 16th century granite fort in Vellore, mainly due to depletion in the oxygen level in the water.
Officials of the Department of Fisheries said that most of the fish that were found dead in the moat was Jalebi fish (zoological name: Tilapia fillets). The fish is a common variety from fresh and brackish waterbodies. As per estimates, over 50 kg of fish were removed from the moat by the department on Saturday. “Soaring temperature, especially during summer, is also another reason for small fish varieties to die. We are analysing the cause of death,” said an official of the Fisheries Department.
