Combined LED light source for reducing cannibalism rate of garrupa and application thereof

Abstract

The invention provides a combined LED light source for reducing the cannibalism rate of garrupa and application thereof. According to the method, the purpose of reducing the cannibalism rate is achieved by combining the environment control technology and an accurate feeding manner by means of the environment control technology of creating a specific light environment, the illumination time and the illumination intensity in an industrialized garrupa aquaculture workshop. The method is specially developed according to the avoidance tendency of main garrupa culture species such as saddletail groupers, pearl gentian groupers and epinephelus septemfasciatus to the specific spectra, light intensity and illumination period and the appetite regulation and control rules of epinephelus coioides juveniles. By means of the method, the cannibalism of the garrupa can be effectively restricted, and economic losses caused by cannibalism during the intermediate culture period of industrialized garrupa seedlings are remarkably decreased. Moreover, operations is easy and convenient, the automation degree is high, the health, safety, energy conservation and environment protection are realized, and the method has high application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of fish farming in agricultural aquaculture, and in particular relates to a combined LED light source for reducing the residual food rate of grouper and its application. Background technique [0002] Cannibalism is a behavior of killing each other (eating) among the same species. Cannibalism is common in fish. Studies have confirmed that cannibalism exists in 36 families of fish, including some important type of economy. Grouper (Epinephelus) fish, belonging to the order Perciformes, also known as: grouper, is a warm-water offshore bottom rare fish, distributed in the western North Pacific Ocean, China is mainly produced in the South China Sea and the southern part of the East China Sea, the meat of the grouper It is plump, tender, and nutritious. It is a low-fat, high-protein high-quality edible fish. Among the grouper species distributed along the coast of my country, the economic value is higher: saddle b...

AI Technical Summary

Problems solved by technology

At present, a large number of self-mutilation behaviors appear in grouper factory breeding, which seriously affects the survival rate and industrial economic benefits of grouper factory breeding. In industrial farming, it is an inevitable trend to improve the farming environment, improve the level of fish welfare farming, reduce energy consumption and farming costs through updating farming equipment. Therefore, the industry urgently needs a method that uses light regulation to reduce grouper cannibalism. High-efficiency factory farming methods, but at present there is still a lack of inventions that use LED light sources to carry out related work in factory grouper farming
