Problems solved by technology

[0003] In the current aquaculture, most of them adopt the form of polyculture, that is, there are adult fish and juvenile fish in the breeding pond. On the one hand, due to the weak active predation ability of juvenile fish, on the other hand, there is vicious competition for food, resulting in some juveniles. During the growth period, the fish will grow slowly or even die, causing certain losses

Abstract

The invention discloses a feeding method of a juvenile fish feed for aquaculture, belonging to the technical field of aquaculture. According to the method, a feed suction ring can be bound at the tail of a juvenile fish, so the feed special for the juvenile fish is attracted to be concentrated at the tail by utilizing magnetic attraction force, and the feed automatically falls off and is eaten by the juvenile fish when the juvenile fish swings the tail; and thus, the method can effectively supplement nutrients required by the growth of the juvenile fish, ensure sufficient food intake of the juvenile fish, avoid the hunger problem caused by malignant competition, cultivate the fishtailing feeding habit of of the juvenile fish, exercise the athletic ability of the juvenile fish to a certain extent and improve the growth health degree and flesh taste of the juvenile fish. In addition, the feed suction ring can realize automatic matching according to growth of the juvenile fish, then magnetic suction force is automatically adjusted to adapt to special feeds for the juvenile fish in different growth stages, and the feed suction ring can be recycled, so the survival rate and value of the juvenile fish are improved while breeding cost is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and more specifically, relates to a juvenile fish feed and a feeding method for aquaculture. Background technique [0002] Aquaculture is the waters that humans use for breeding (including planting). According to the ecological habits of the breeding objects and the different requirements for the environmental conditions of the waters, aquaculture technology and facilities are used to engage in aquatic economic animal and plant breeding. one. According to the nature of the waters, it is divided into marine aquaculture and freshwater aquaculture. According to the breeding and planting objects, it is divided into fish, shrimp and crab, shellfish, algae, gorgon, lotus, lotus root, etc. The aquaculture industry in China has a long history. As far back as 1142 BC (the end of the Yin Dynasty and the beginning of the Zhou Dynasty), it was known to dig ponds to raise fish. Fan Li wrote the "Fish Cu...
