Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and in particular to a pond fish farming zone feeding combined device. Background Art

[0002] For fish co-breeding, it is usually necessary to consider a variety of factors such as water temperature, water quality, bait, stocking density, fish size, etc. Since silver carp and grass carp are both subtropical fish, the suitable water temperature is 20-30℃, the suitable water pH is between 6.5-8.5, and since silver carp and grass carp are similar in size, fighting between fish caused by size differences can be avoided.

[0003] When grass carp and silver carp are co-raised, due to the different feeds they feed, during the centralized feeding process, the feed amount is difficult to determine due to the mutual occupation of feeding areas. When the feed amount is too much, there will be too much feed residue at the bottom of the pond, thus affecting the water quality. Moreover, due to poor feeding effect, the growth rate and yield of grass carp and silver carp are easily affected. Utility Model Content
