A large-scale breeding method for large-scale fish species of red-eyed trout

Abstract

The invention discloses a large-sized squaliobarbus curriculus fingerling large-scale culture method which includes the steps: pond selection; pond cleaning disinfection; water bloom stocking; bait feeding; water quality management. According to the method, the key of squaliobarbus curriculus fingerling large-scale culture technology is successfully broken through firstly in domestic, squaliobarbus curriculus feed serves as a fertilizer for culturing natural food organisms in fertilizer slow-release technology, squaliobarbus curriculus fingerling culture, domestication and food conversion are organically combined, squaliobarbus curriculus fingerlings with different sizes are smoothly supplied, operation procedures are simple and convenient, management is easy, the squaliobarbus curriculus fingerlings are directly and successfully domesticated and fed by artificial compound feed originally in terms of fingerling culture, bait feeding and the like, the survival rate of the fingerlings is 85% or more, culture water quality can be kept good, the most effective culture method and technology are created for sufficiently developing squaliobarbus curriculus as a culture species or mandarin fish culture bait fish, and the method has important social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a large-scale breeding method for large-scale fish species of red-eyed trout. Background technique [0002] Red-eyed trout, known locally as red-eye trout and ginseng fish, has a long cylindrical body, round belly, flattened rear, silver-white body color, slightly dark gray back, and a prominent red spot on the upper edge of the eye, so it is called red-eyed trout; [0003] Red-eyed trout grows fast and has a strong ability to adapt to changes in the external environment. Because of its high meat content, good taste, fresh and tender meat, and rich nutrition, especially as a supporting breeding of bait fish species, it can greatly promote my country's The industrial development of carnivorous fish such as mandarin fish in the central and northern regions has attracted more and more attention and favor from farmers. [0004] Red-eyed trout live in the middle and upper layers o...

Problems solved by technology

[0005] At present, in the process of artificial breeding of red-eyed trout, especially the seedling breeding technology is still in the exploratory stage. Generally, the breeding methods of other fish species are used to breed red-eyed trout, but the breeding effect is not ideal. Relatively low or very unstable; in this field, regarding the cultivation of red-eyed trout seedlings, the cultivation of pond bait organisms is generally used to produce large-scale red-eyed trout seedlings;
