A kind of directional breeding method and application for Yuanbao grade blood parrot

Abstract

The invention relates to a directional cultivation method for ingot-grade blood parrots. The method is composed of a fish flower cultivation stage, a fry cultivation stage and an adult fish cultivation stage. This method can quickly shape the blood parrots, obtain high-quality ingot-level blood parrots, improve the success rate of ingot-level blood parrots, and the bred ingot-level blood parrots have a stable body shape, which is not easy to lose shape in later breeding, and the selection rate is up to More than 40%, the economic value is more than 2 times that of ordinary blood parrots, and it also solves the problem of low selection rate of conventional breeding Yuanbao grade blood parrots, and can effectively solve the problem of unstable breeding of high-end blood parrots in the current blood parrot breeding process.

Description

technical field [0001] The invention belongs to the technical field of ornamental fish breeding, in particular to a directional breeding method and application for ingot-grade blood parrots. Background technique [0002] The blood parrot originated in Taiwan, China. It belongs to the Cichlidae family of Perciformes in taxonomy. It is a new species of ornamental fish that is a hybrid of purple red crater and red devil. Because of its bright red body, short and round body, heart-shaped mouth that cannot be closed, and It has the meaning of attracting wealth and treasure, expelling ghosts and town houses, etc., and is deeply loved by consumers. In recent years, with the gradual improvement of blood parrot breeding technology and the continuous improvement of people's aesthetic requirements, consumers have higher and higher requirements for blood parrot grades. The B-grade fish and A-grade fish that originally circulated in the market are no longer available. To meet the needs ...

AI Technical Summary

Problems solved by technology

Reservoir cage culture mode, the main breeding area is Hainan Island in China. The blood parrots bred are all fish species that have been selected with pointed heads and incomplete fading in the early stage, so the ingot-grade blood parrots bred are selected. The yield rate is high, and there are few defective products. However, due to its fast growth rate and poor body shape stability, it is easy for consumers to breed it in the later stage. With the enhancement of people's awareness of environmental protection, this farming model has gradually been eliminated. ; while the main breeding area of ​​the workshop+greenhouse culture mode is the northern region of China, which is generally shown as hatching in the workshop and breeding in the greenhouse. Because the breeding cost of this mode is higher than that of cage culture, the general density of blood parrots cultured is average. It is relatively large and needs to be selected progressively. The blood parrots put into breeding in this mode are counted from the seedlings, so the selection rate of the ingot-level blood parrots is low; the workshop + greenhouse + outer pond relay breeding mode, this mode is in It was developed on the basis of the workshop + greenhouse breeding mode. The main feature is to take advantage of the high temperature in summer in the northern region and the rich bait organisms in the outer pond to carry out relay breeding. After the weather turns cold, it will be poured into the greenhouse for overwintering breeding. Compared with the workshop + greenhouse breeding mode, the breeding cost is lower, and the blood parrots bred are more beautiful in size and body color. Generally speaking, the selection rate of ingot-grade blood parrots bred in this mode is slightly higher than that of workshop + greenhouse breeding model
