Background

In the aquaculture of aquatic fishes, omnivorous fishes occupy a large proportion, and common artificially cultured omnivorous fishes comprise carps, crucian carps, tilapia and the like. Omnivorous fish is a fish which has wide feeding property and can eat animal food and vegetable food, such as small crustacean, insect larva, worm, shellfish, etc., and vegetable rice, bean and other plant debris. Common omnivorous fishes such as tilapia and the like have short breeding cycle and strong breeding capability, are widely cultivated at home and abroad, and have large market demand. The supply of high quality fry becomes a key limiting factor for the development of the omnivorous fish industry. Under the condition of artificial breeding, the artificially prepared granular feed and powdery feed are mostly used as main food of the fry. Omnivorous fries prefer food that moves about in the body of water, while food that sinks to the bottom of the water is less interesting for ingestion. Therefore, the feed is a main stage for feeding omnivorous fry from the time when the feed is fed to the underwater, and the feed submerged in the underwater is difficult to be fed by omnivorous fry. Therefore, in the process of breeding omnivorous fish fries, a large part of feed is still reduced to be ingested by the fish fries due to the fact that the feed is thrown (thrown) during the cultivation of omnivorous fish fries, the feed intake of omnivorous fish is insufficient, the feed is wasted, and the aquaculture water body is polluted.
