Automatic feeding system and method for circulating flowing water culture

Abstract

The invention discloses an automatic feeding system and method for circulating running water culture, and relates to the technical field of aquaculture, the automatic feeding system comprises a culture tank, a water temperature monitoring unit, a culture tank dirt recycling device, a controller and an adjustable bait casting machine unit; the water temperature monitoring unit is arranged in the culture tank and receives the water temperature in the culture tank; the breeding tank dirt recovery and treatment device is communicated with the tail part of the breeding tank and is used for collecting and treating dirt in the breeding tank; the water temperature monitoring unit and the breeding tank sewage recovery processing device respectively transmit a water temperature signal and a sewage weight signal to the controller; the adjustable bait casting machine unit is installed above the breeding tank and connected with the controller. By the adoption of the technical scheme, the feeding amount can be automatically adjusted according to changes of the breeding environment, scientific feeding is achieved, cost is saved, water quality is protected, and the yield and quality of fishes are improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an automatic feeding system and method for circulating water aquaculture. Background technique [0002] China is a big fishery country, and aquaculture has become the main fishery in the production of aquatic products, especially the fish farming industry, which is the main guarantee for the supply of animal protein. It is determined by environmental factors such as the water temperature of the breeding tank and the actual growth stage of the fish. The traditional feeding method of fish farming is based on experience in regular and quantitative feeding. This feeding method cannot be accurately adjusted according to the changes in the breeding environment and the growth habits of fish. Many of them will lead to waste of bait, increase the cost of breeding, and the excess bait will affect the water quality of the breeding tank. [0003] In order to solve the above problems, t...

Problems solved by technology

However, there are two problems with this method. On the one hand, image recognition of fish movement trajectory is difficult to accurately measure and the workload is heavy. On the other hand, this method cannot accurately adjust the amount of fish fed according to the growth stage of fish and the breeding environment.

Another example is the Chinese invention patent application number CN201810231326.3, which provides a fuzzy algorithm-based method for estimating the amount of fish fed. According to the average body weight and water temperature of the fish, the fuzzy algorithm is used to estimate the amount of fish fed. This method The average weight of the fish is used to determine the growth stage of the fish and then determine the food intake. At the same time, the influence of the water temperature on the food intake of the fish is also considered, but the situation of feeding too much bait is not taken into account, and the accurate feeding of bait and excessive feeding cannot be detected in time. Difference, easy to cause waste of bait
