Abstract

The invention relates to a block-type aquaculture precision and intelligent feeding system and method. The feeding method includes: turning on the feeder, and setting the feeder to a low-power feeding mode, so that the feeder performs feeding inside the block; obtaining the activity pressure signal of the fish school on the block; Judging whether the active pressure signal reaches a pressure peak value, if so, switching the low-power feeding mode to a high-power feeding mode, so that the feed of the feeder is sprayed to the outside of the block; When the peak pressure drops, it is judged whether the active pressure signal is lower than the pressure threshold, and if not, the feeder is turned off. The invention can reduce individual differences, reduce the phenomenon of killing among species, avoid the waste of feed, and avoid the pollution of water caused by excessive feed.

Description

technical field [0001] The invention relates to the field of breeding equipment, in particular to a block-type aquaculture precision intelligent feeding system and method. Background technique [0002] Carnivorous fish, in the breeding process, have strong feeding habits, large food intake, and will kill each other, especially in the case of insufficient food. Fishermen usually judge the amount and time of feeding according to their own experience. There are many problems in this way: on the one hand, the food intake of fish is the result of the joint action of many factors, which cannot be determined by human observation alone. Accurately judge the feeding amount of feed. For carnivorous fish, if the amount of feeding is too small, not only will some fish not be able to maintain a normal growth rate, but they will be too small to compete for food with the same species, and they will be easily attacked by other fish. affected the economic benefits. If the amount of feedin...
