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

Embodiment 1

[0025] as attached figure 1 As shown, the present invention provides a combined LED light source for reducing self-mutilation behavior of grouper in the intermediate cultivation of grouper. A combined LED lamp group composed of LED light-emitting chips, a light source control system and a waterproof casing. The composite LED lamp group and the light source control system are wrapped with the waterproof casing. A circuit control module for the light intensity and light time of the LED light group, the combined LED light group is electrically connected to the light source control system, so as to realize the control of the light intensity and light time of the LED light group by the circuit control module, and the waterproof shell uses Anti-corrosion materials and use sealant for waterproofing.

[0026] The combined LED lamp group contains two kinds of cold white and red monochrome LED light-emitting chips arranged according to a certain ratio, and the quantity ratio of the two...

Embodiment 2

[0030] The volume is 2m 3 There are 4 water tanks, one of which is equipped with the combined LED lamp as the experimental group, and one of the water tanks is illuminated by ordinary incandescent lamps as the control group, and each of the experimental group and the control group is respectively set up to repeat. When the lighting is turned on, the light intensity on the water surface of each tank is 100-300 lux.

Abstract

The invention provides a combined LED light source for reducing the residual food rate of grouper and its application. The invention adopts the environment control technology of creating a specific light environment, light time and light intensity in the industrialized grouper breeding workshop, and combines the environment control technology with the precise feeding method to realize it together. The present invention is specially developed according to the tendency and avoidance habits of main grouper cultured species such as oblique-banded grouper, pearl gentian and seven-banded grouper to specific spectrum, light intensity and light cycle, and the appetite regulation rule of young grouper fish , this method can effectively inhibit the grouper self-mutilation phenomenon, significantly reduce the economic loss caused by residual food in the intermediate cultivation stage of industrialized grouper fry, and is easy to operate, high in automation, healthy and safe, energy-saving and environmentally friendly, and has a high promotional value 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...
