On the advice of Fisheries Department, the Forest Department is in the process of destroying eggs of predatory catfish on the surface of Vellode tank.
Proliferation in the population of catfish had led to drastic reduction in the numbers of popular fish varieties such as katla and jalebi.
The output of the popular fish varieties had witnessed a steep decline due to the predatory nature of the catfish, department sources said. There was no clue on how the catfish, that is not preferred for consumption, found its way into the Vellode tank, as, the fishlings of this variety is not raised anywhere in the State, Forest department sources said.
The eggs of the catfish found on the surface is being destroyed by dislocating the soil.
According to a senior official, the eggs of catfish will be destroyed entirely before release of fishlings of popular varieties ahead of the monsoons when the tank, a noted sanctuary for birds, gets full.
