Problems solved by technology

The feeding status, growth rate and survival rate of California perch juveniles during this period directly affect the robustness and growth performance of California perch in the middle and late stages of culture, thus affecting the market speed and economic benefits of California perch
At present, juvenile fish still have the problems of inactive feeding and low survival rate, resulting in high seedling costs, which have been plagued by the development of the California perch industry.

Embodiment 1

[0028] The water circulation aquaculture system includes a pre-filter tank (water volume 300L) and 4 independent water circulation culture tanks (water volume of each tank is 175L). The filter tank and the culture tank are connected by pipes to realize the circulation of the culture water.

[0029] Hydrogen production process: The hydrogen production equipment is a water electrolysis hydrogen production machine (hydrogen production power is 1000ppm / hour / ton). The electrolyzed water hydrogen generator electrolyzes the distilled water into hydrogen and oxygen with a purity of 99.99% through the hydrogen-oxygen separation electrolyzer in the equipment, in which the oxygen is discharged from the machine, and the water in the filter tank passes through the water inlet pipe of the electrolyzed water hydrogen generator and hydrogen in hydrogen production The mixed hydrogen water is mixed in the hydrogen mixing device inside the machine, and the mixed hydrogen water enters the filter t...

Abstract

The invention discloses a culture method for improving ingestion, growth speed and survival rate of micropterus salmoides at a fry culture stage, and belongs to the technical field of culture. According to the method, in a water circulation culture system, the hydrogen concentration in culture water reaches 900-1100 ppm and is kept for 45 min. Compared with a common domestication mode, the green and economical culture method for improving the ingestion, the growth speed and the survival rate of the micropterus salmoides at the seedling culture stage has the advantages that hydrogen is introduced into the culture water to directly stimulate high expression of the appetite factor neuropeptide Y, and the ingestion, the growth speed and the survival rate of the micropterus salmoides at the fry culture stage can be remarkably improved.

Description

technical field [0001] The invention relates to the field of breeding technology, and more specifically relates to a breeding method for improving the feeding, growth rate and survival rate of California perch in the seedling cultivation stage. Background technique [0002] Juveniles (1-3cm) are an important growth stage for California perch to grow from splashes to robust juveniles. The feeding status, growth rate and survival rate of juvenile California perch during this period directly affect the robustness and growth performance of California perch in the middle and late stages of culture, thus affecting the market speed and economic benefits of California perch. At present, juvenile fish still have the problems of inactive feeding and low survival rate, resulting in high seedling costs, which have always plagued the development of the California perch industry. [0003] The prior art mainly improves the food intake, growth rate and survival rate of juvenile fish by imp...
