[0001] The utility model relates to the aquaculture technical field, concretely is a kind of baiting device for freshwater fish culture. BACKGROUND

[0002] Freshwater aquaculture refers to the production of feeding and breeding aquatic economic animals such as fish, shrimp, crab, shellfish and aquatic economic plants by using ponds, reservoirs, lakes, rivers and other inland waters containing slightly salty water, which is an important part of inland water industry. The main objects of cultivation are fish, and the main cultivated shrimp species are Macrobrachium rosenbergii and Hainan prawn, and the main cultivated crab species is river crab. Freshwater fish mainly includes: grass carp, grass carp, silver carp, bighead carp, common carp, crucian carp, bream, bream, bream, non-crucian carp and other economic fish. With the rapid economic development, more and more people engage in freshwater fish culture, and the scale of culture is increasing.

[0003] However, during the cultivation process, especially during the feeding of freshwater fish, most of the feeding is carried out by artificial throwing and scattering. When artificial throwing and scattering bait, the bait is not evenly scattered, which causes crowding during feeding. Moreover, this operation method has high labor intensity and is time-consuming and laborious.

[0004] To solve the above problems, we propose a baiting device for freshwater fish culture to solve the above problems. UTILITY MODEL CONTENT
