Fish bait casting quantity control system for deep-water cage culture

Abstract

The invention discloses a fish bait casting quantity control system for deep-water cage culture, and system obtains the water temperature, salinity, dissolved oxygen concentration, water flowing speed and cultured fish weight of a controlled deep-water net cage at n historical collection moments through a control host, and enables the obtained data to be inputted to a support vector machine model for processing, and then selects an optimal support vector machine model based on the judgment of a mean square error and a square related coefficient of the support vector machine model. The system can predict the result of the cultured fish weight according to the environment factor data of fishes cultured in the controlled deep-water net cage at the current moment, sends a corresponding bait casting quantity control instruction based on the result, and enables a bait casting machine disposed on the deep-water net cage to cast bait according to the bait casting quantity control instruction. The system can achieve the automatic and high-precision bait casting for all deep-water net cages under a specific environment factor, reduces the bait waste and environment pollution which are caused by unreasonable casting, and greatly improves the culture benefits.

Description

technical field [0001] The invention relates to a system for controlling the feeding amount of fish used in deep-water cage culture. Background technique [0002] With the scale and intensification of deep-water cage culture and the expansion of distant sea culture in my country's mariculture, higher requirements are put forward for the accurate and timely breeding control of deep-water cage culture. It is very important. Since the deep-water cage culture site is far away from the shore, manual on-duty monitoring will also be "one hundred secrets and one sparse", resulting in losses. Conventional wired monitoring, because of the marine aquaculture environment, the network wiring brings great inconvenience to the construction and breeding ships, and the wired network is very easy to be damaged. [0003] In the process of deep-water cage culture, it is necessary to comprehensively monitor the breeding objects, net clothes, and breeding environment. The ultimate goal of deep-w...
