Fish predators of pest control (birds)
Supervision on the cultivation of fish (fish hatchery) is a way to control pest bird predators.
Oversight of predatory birds can be done by way of expulsion if we see the presence of birds.
Another control that can be done is by installing a barrier so that the bird is not easy to pounce on the fish. Barriers can be made from bamboo tassel or cord barrier. Twigs or branches of dead trees that are all around the pond should be discarded in order not to be used as predator fish, bird perches.
