High-density rotifer culture device and method

Abstract

The invention discloses a high-density rotifer culture device and method. The rotifer breeding device comprises a breeding trough, a microalgae culture barrel and a central control system. The methodcomprises the steps of pre-treatment of the rotifer culture device, microalgae culture, rotifer culture, rotifer collection and cyclic breeding; and through the central control system, the microalgaeculture barrel is controlled, carbon dioxide is continuously supplied to accelerate growth of microalgae, the growth requirements of rotifers are met by controlling the microalgae culture barrel to transport high-density microalgae, as feed, to the breeding trough, and by filling the breeding trough with pure oxygen, and after the rotifers grow to certain density, the central control system conducts pollution discharge and rotifer collection on the breeding trough, and recycles a rotifer culture solution. Through the culture device with dissolved oxygen and high-density food in water increasedand cyclic supply achieved, high-standard high-density rotifer culture is achieved, and the survival rate and the breeding efficiency of rotifer breeding are improved.

Description

technical field [0001] The invention relates to the field of biological cultivation, in particular to a high-density rotifer cultivation method and device. Background technique [0002] Rotifers are smiling multicellular organisms, not only rich in the three basic nutrients of protein, fat and carbohydrates, but also contain various amino acids, vitamins, high unsaturated fatty acids and other biologically active substances. In the field of domestication of aquatic organisms, it is often used as live bait for seedlings. Because of its excellent feeding effect, rapid self-reproduction, strong vitality, and suitable size, it provides the best bait for the domestication of fish and shrimp aquatic organisms. It is widely used in aquaculture. [0003] In recent years, with regard to the protection of ecological aquatic resources, the implementation of water resource protection and continuous plan for the return of seedling breeding, the cultivation of aquatic seedlings has been ...

AI Technical Summary

Problems solved by technology

[0003] In recent years, with regard to the protection of ecological aquatic resources, the implementation of water resource protection and continuous plan for the return of seedling breeding, the cultivation of aquatic seedlings has been paid more and more attention, which has prompted the development of a variety of better and more economical bait. At present, the most used and cost-effective bait The highest rotifer, the mainstream cultivation method in China adopts the open outdoor large pond for extensive cultivation, and uses organic matter to ferment fertilizer and water. This cultivation has seasonal restrictions, weather restrictions, and it is difficult to control the number of species and the influence of the outside world.
