Fixed-point feed feeding method for aquaculture

Technical Field

The invention relates to the technical field of aquaculture, in particular to a fixed-point feed feeding method for aquaculture.

Background

The aquaculture industry is a water area which can be used by human beings for cultivation (including planting), and is one of agricultural production departments, wherein aquatic economic animal and plant cultivation is carried out by applying aquaculture technology and facilities according to the ecological habits of cultivation objects and different requirements on the environmental conditions of the water area. According to different water area properties, the method is divided into a mariculture industry and a freshwater culture industry. According to the objects of cultivation and planting, the fish, shrimp, crab, shellfish, algae, gordon euryale seed, lotus root, etc. are divided into fish, shrimp, crab, shellfish, etc. The Chinese aquaculture industry has a long history, and fish culture in pool chiseling is known as 1142 years before the Yuan (the beginning of the last week of Yin), and the Liang is recorded in the Fish culture Jing of 460 years before the Yuan, which is the earliest fish culture literature in the world. After a new Chinese is established, all water areas and potential water areas which can be used for cultivation are greatly improved and utilized, the cultivation area is enlarged, and the yield of unit area (water body) is improved; developing new fields and new ways of aquaculture, developing the aquaculture of factory, mechanization, high-density warm running water, net cages (including multilayer net cages), artificial fish reefs, three-dimensional, intercropping and mixing and the like, developing towards the direction of intensive operation, and exploiting the potential of aquaculture production; the aquatic resources and the ecological environment are protected, and the aquaculture industry is developed quickly.

In present aquaculture, the fodder is all directly thrown and fed to breeding the pond, leads to some fodder to sink the end back fish to be difficult to discover and cause the waste, and the fodder also needs to be thrown and fed frequently simultaneously, and is difficult to judge the consumption of fodder and in time supply, and too much too little fodder in breeding the pond is unfavorable for the growth of fish.
