Food is the main element for living of all animal. Like other animals fish also needs sufficient and nutritious fish feed for proper growth and survival.
Maximum fish production is not possible without nutritious feed. The ingredients of well balanced nutritious feed for fish are protein, carbohydrate, fat, vitamins, minerals and water.
The feed like moss or aquatic insects which produce naturally in the pond is not sufficient for fish. There are some natural feed in the pond initially which may consumed by fish within a few days.
Applying fertilizer in the pond for producing natural feed also can’t make proper and necessary feed production. As a result the fishes can’t grow fast.
Along with natural feeds, supplementary feed ensures the fast growth of fish. So, it is a must to use supplementary feed in the pond for high production of fish within short time in small place.
