AGARTALA: Rameshwar Das, the Principal Secretary of Tripura’s Fisheries Department, has backed Chief Minister Biplab Deb’s comments about raising oxygen levels in water bodies by releasing ducks, saying that bird is a natural aerator and its presence in water bodies provides multiple benefits.
“The practice of introducing something else with fish is known as Integrated Fish Farming. It is used in animal husbandry, agriculture, etc. There are several benefits of introducing ducks with fish. Firstly their droppings increase the fertility and helps raise the level of plankton in the water, which the fish consume, hence helping them grow,” Das told ANI.
Das further explained how ducks act as natural aerators, “Fish require dissolved oxygen. The surface area of the water body is directly proportional to the dissolved oxygen, and to increase the surface area, there needs to be a disturbance on the surface, it cannot be still. So, when ducks swim on water, they act as natural aerators, and with ducks not there, we have to artificially aerate the waters,” he said.
