Professor Abdullah Harun Chowdhury, a Khulna University’s Faculty of Environmental Science teacher, said, “All types of fish, big and small, are harmed if poison is applied. The fry dies.

Besides, when the polluted water goes towards the deep sea due to the tide, the area’s aquatic life is also affected. Besides, the effect of mixed poison in the surrounding soil remains for a long time.”

As a result, the reproductive capacity of aquatic animals is reduced, and health is affected. The number of aquatic animals is decreasing day by day. Birds and larger animals that survive on these fish are also being harmed. As a result, the life cycles of fish, birds, and other animals dependent on fish are changing.
