A factory farming lighting system and its application to promote the growth of grouper fry and improve the survival rate

Abstract

The present invention provides an industrial farming lighting system for promoting the growth of grouper fry and improving the survival rate and its application. Lamp group, light source control system and waterproof housing, wherein the light source control system includes a power supply module and a circuit control module, which can control the light intensity and light time of the composite LED light group. The waterproof case uses anti-corrosion materials and sealant for waterproofing. The present invention develops and sets according to the preferences of grouper juveniles for specific spectrum, light intensity and photoperiod, can meet the needs of industrialized cultured grouper juveniles for light color, light intensity and photoperiod, and promote The healthy growth and survival rate of fish can be improved, and the economic benefits of factory grouper farming can be improved.

Description

technical field [0001] The invention belongs to the field of aquaculture equipment, and in particular relates to an industrial farming lighting system for promoting the growth of grouper fry and improving the survival rate and its application. Background technique [0002] At present, the precious seawater fish cultured in my country, such as turbot ( Scophthalmus maximus ), flounder ( Paralichthys olivaceus ), red sea bream ( Pagrus major ), black sea bream ( Sparus macrocephalus ) and grouper ( Epinephelus ), etc., in the nursery stage, there are a large number of larvae and juveniles dying, and the survival rate is generally lower than 20%. The reason is closely related to the breeding environment. As a complex and special external ecological factor in the aquatic environment, light includes spectrum, light intensity and photoperiod. Practice has proved that the sensitivity of fish to light changes varies with fish species and developmental levels. Light will sig...

Problems solved by technology

[0004] Although more and more studies have proved the importance of artificial light in fish farming, at present, due to the lack of sufficient understanding of the importance of artificial light regulation, it is widely used in domestic seawater fish factory culture workshops. The main lighting source is still an incandescent lamp or a fluorescent tube, and its disadvantages are: 1) The fluorescent tube will pollute the environment during the production process and after it is scrapped, mainly mercury pollution, which will pollute water resources; 2) The color of the incandescent lamp and fluorescent tube 3) Traditional light sources such as fluorescent lamps and incandescent lamps have a wide spectrum, and some unnecessary wavelengths will be mixed in the monochromatic light to make the monochromatic light Not pure enough, and the controllability of fluorescent lamps is poor, the light intensity and light color cannot be adjusted, and there will be ultraviolet radiation; 4) The life of incandescent lamps and fluorescent lamps is short, and the longest service life is only 10000h, while in the breeding factory In such a dark and humid environment, the service life will be greatly shortened

5) The efficiency of incandescent lamps and fluorescent tubes is relatively low, about 60% of the electrical energy can be converted into ultraviolet light, and the rest can be converted into heat energy

With the development of the grouper aquaculture industry, it is an inevitable trend to improve the aquaculture environment, improve the level of fish welfare aquaculture, and reduce energy consumption and aquaculture costs through the renewal of aquaculture equipment in grouper industrial aquaculture. The special LED light source developed by factory grouper farming has not been reported at home and abroad.
