Embodiment 1

[0015] In the Zhuanghe Redfin puffer factory breeding base in Liaoning Province, during the breeding process of the fertilized eggs of the redfin puffer: the hatching water temperature of the fertilized eggs is 19-19.5℃, the water depth is 55cm, and a full-spectrum LED light source is hung 100cm above the water surface. , the photoperiod is 24h of light, and the light intensity is 0.5W / m 2 , obtained fertilized eggs through wet artificial insemination, washed with sea water for many times to remove sperm and blood clots, and then fished out 25g of washed fertilized eggs with a net bag, placed in a breeding bucket according to the conventional breeding method, and inflated until the fertilized eggs floated in the water, The water is changed every 2 hours during the day and every 4 hours at night. The amount of water for each change is 100-200%. The seawater used needs to be treated by sedimentation, sand filtration and aeration. The total ammonia nitrogen and nitrite concentrat...

Embodiment 2

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

Abstract

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. The method of the present invention is to set an LED light source on the water surface; in the process of cultivating fertilized eggs of puffer puffer, the LED light source is a full spectrum; in the process of cultivating juvenile puffer fish, the LED light source is : 525‑530nm green light or 590‑595nm yellow light. The invention further improves the survival rate of the seedlings and promotes their growth by regulating the illumination parameters during seedling cultivation, so as to improve the production efficiency and economic benefits of the industrialized seedling cultivation of the redfin puffer.

Description

technical field [0001] The invention relates to a method for promoting the survival and growth of red-finned pufferfish from fertilized eggs to juveniles by using an LED light source, and belongs to the technical field of factory 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. Light is one of the important environmental factors, and it 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 fish feed and communicate mainly through vision. Therefore, the lighting conditions used in aquaculture production should increase the visual range of fish, shorten the feeding time, and ultimately promote their growth and survival. [0003] Due to the abundance of su...
