Novel Leiocassis longirostris breeding system capable of automatically adjusting feeding amount

Abstract

The invention discloses a novel Leiocassis longirostris breeding system capable of automatically adjusting feeding amount. The system comprises a collecting unit, a storing unit, a feeding unit and a control unit, wherein the collecting unit is used for collecting the integral infrared image information of the interior of a fishpond; the storing unit is used for storing a corresponding list of the fish volume sum V and the feeding amount sum W; based on an instruction of the control unit, the targeted feeding amount of food is fed into the fishpond by the feeding unit; the integral infrared image information of the interior of the fishpond is acquired by the control unit at t<1>, t<2>...t<n>, the fish volume sum V<1>, V<2>...V<n> in the fishpond is calculated based on the infrared image information, when V <= a*V<i-1>, the control unit sends W<i-1> as the targeted feeding amount to the feeding unit and controls the feeding unit to take action through the instruction, and when a*V<i-1> < V and V <= b* V<i-1>, the feeding amount sum W corresponding to V is searched in the storing unit by the control unit, and the control unit sends W to the feeding unit and controls the feeding unit to take action through the instruction. According to the system, a feeding strategy is selected and adjusted based on changes of the fish volume in a targeted mode, intelligentization and automation of the fish breeding system are improved, and the effect and efficiency of fish breeding are guaranteed.

Description

technical field [0001] The invention relates to the technical field of intelligent breeding, in particular to a novel channel catfish breeding system capable of automatically adjusting the feeding amount. Background technique [0002] Aquaculture fishery is one of the fastest growing sectors of food production in the world to make up for the lack of global aquatic product supply. However, the sustainable development of aquaculture fishery is mainly limited by outdated and backward aquaculture facilities, shortage of land resources, lack of water quality resources, and high labor costs. [0003] Under the existing breeding technology, farmers often use artificial feeding to feed the fish. In the selection of fish feeding amount, farmers usually select the feeding amount of fish roughly according to the survival time of fish and the method of identifying fish volume with the naked eye. There are many disadvantages in this selection method: The growth rate is different, and it...

Problems solved by technology

In the selection of fish feed amount, farmers usually roughly choose the fish feed amount according to the survival time of the fish and the method of identifying the fish volume with the naked eye. There are many disadvantages in this selection method: The growth rate is different, and it is difficult to measure the volume of fish in the entire fish pond based on the volume of a few fish; the volume change of fish is continuous, and it is difficult to recognize the change of fish volume in a short period of time; coupled with the limitation of artificial feeding characteristics, making it difficult to formulate the fish food put into the fish pond according to the distribution of fish populations, and often there will be situations where fish eat more and eat less in a certain area, or fish eat less and eat more
