A fish feeding control system for deep water net cage culture

Abstract

The invention discloses a fish feeding amount control system for deep-water net cage culture, which uses a control host to obtain the water temperature, salinity, dissolved oxygen concentration, and water flow velocity of the controlled deep-water net cage at n historical collection moments and the weight of farmed fish, and put the obtained data into the support vector machine model for processing, and then select the optimal support vector machine model based on the evaluation of the mean square error and square correlation coefficient of the support vector machine model, which can be based on the received Controlling the environmental factor data of the currently farmed fish in the deep-water cage at the current moment predicts the weight prediction result of the farmed fish, and then issues a corresponding bait feeding amount control command based on the result, so that the bait feeding machine set in the deep-water cage Quantity control command to cast bait. The invention can realize automatic and high-precision feeding of each deep-water net cage under specific environmental factors, reduces problems such as bait waste and environmental pollution caused by unreasonable feed feeding, and greatly improves breeding 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...
