Embodiment 1

[0015] In the factory breeding base of red-finned puffer in Liaoning Zhuanghe, during the cultivation of fertilized eggs of puffer, the fertilized eggs hatch at a water temperature of 19-19.5°C and a water depth of 55cm. A full-spectrum LED light source is hung 100cm above the water surface. , the photoperiod is 24 hours of light, and the light intensity is 0.5W / m 2 / S, fertilized eggs were obtained by wet artificial insemination, washed with sea water several times to remove sperm and blood clots, and then 25g of fertilized eggs after washing were fished out with a net bag, placed in a breeding bucket according to conventional cultivation methods, and inflated until the fertilized eggs floated In the water, change the water every 2 hours during the day and every 4 hours at night, and the water change is 100-200%. The density, total ammonia nitrogen and nitrite concentration were maintained within the normal range. After 5 days of cultivation, the red flag puffer began to hatc...

Embodiment 2

[0018] The difference from Embodiment 1 is that the 525-530nm green LED light source is replaced by the 590-595nm yellow LED light source.

Abstract

The invention relates to a method for promoting survival and growth of fugu rubripes from fertilized eggs to larvae and juveniles by using an LED light source, belonging to the technical field of industrial aquaculture. With the method provided by the invention, the LED light source is arranged on the water surface; in the cultivation process of fertilized eggs of the fugu rubripes, the LED lightsource is in a full spectrum; in the cultivation process of larvae and juveniles of the fugu rubripes, the LED light source is green light with a wavelength of 525-530 nm or yellow light with a wavelength of 590-595 nm. According to the invention, through regulation and controlling of illumination parameters in a fry cultivation period, the survival rate of fries is increased, and growth of the fries is promoted, so production efficiency and economic benefit of industrial fry cultivation of the fugu rubripes can be improved.

Description

technical field [0001] The invention relates to a method for using an LED light source to promote the survival and growth of puffer puffer from fertilized eggs to juveniles, and belongs to the technical field of industrial farming. Background technique [0002] Identifying the influence of important environmental and biological factors on fish survival, growth and development is the core content of optimizing factory farming technology. Illumination is one of the important environmental factors, which has an important impact on all stages of fish from embryonic development to sexual maturity. Illumination includes three elements: spectrum, light intensity and photoperiod. Studies have shown that most marine fishes mainly carry out feeding and communication activities through vision. Therefore, the lighting conditions used in aquaculture production should be able to increase the visual range of fish, shorten the feeding time, and ultimately promote their growth and survival...
