Problems solved by technology

In recent years, artificially cultivated flowers and lips Oxygen consumption is high, stress is strong, and it is not easy to catch, which restricts its breeding area and promotion speed
[0003] Currently, in how to solve the flower and lips In terms of the shortcomings of high oxygen consumption and strong irritability, no effective method has been found
Although hybridization technology has a wide range of applications in cultivating fine varieties, it has very high requirements for the selection of hybrid female parents, parents, and hybridization process, otherwise it is difficult to obtain hybrids with better characteristics than their parents.

Embodiment 1

[0025] The flower of this example with lips Hybridization F1 generation seed propagation method, adopts the following steps:

[0026] 1) Breeding of broodstock

[0027] Flowers for broodstock breeding in July 2015 lip Enter the indoor circulating water system to start cultivation.

[0028] Source of broodstock: artificially bred flowers lip Broodstock, cultured individuals with a body length ranging from 15 to 25 cm and a body weight of 180 to 220 g.

[0029] Male to female ratio: female: male = 2~3:1.

[0030] Broodstock breeding pond: adopt the natural water temperature (15°C-25°C) of the indoor circulating aquaculture system for cultivation.

[0031] Water quality control: water for breeding is recycled after being filtered to remove feces and residual bait, plant nitrogen is removed, and ultraviolet sterilized, and new water is added in an appropriate amount. The dissolved oxygen in the breeding water is controlled above 8mg / L, and the ammonia nitrogen is co...

Abstract

The invention provides a flower and lip hybrid F1 generation seedling propagation method. The method includes that parent fish mature rate is up to higher than 75% by taking flower as a female parentand lip as a male parent and controlling parameter conditions during breeding, spawning induction and incubation, maturing time is orderly, brood amount is high, semen quality is high, parent fish egglaying time is uniform, and each of fertilization rate and incubation rate reaches higher than 90%. The method can be used for in-pond artificial seedling culture of hybrid F1 generation and is of important guiding significance in large-scale artificial breeding of F1 generation and comprehensive planting and breeding in a rice field.

Description

technical field [0001] The invention relates to the technical field of hybridization, in particular to a flower with lips Hybrid F1 generation seed propagation method. Background technique [0002] flower and lips Cyprinidae, Cyprinidae, Cyprinidae, belongs to. Distributed in major rivers, lakes, and reservoirs in my country, it is a small and medium-sized fish with high economic value. Its spawning period is from early April to early May, and it is a one-time spawning fish. Heavy eggs, high viscosity, pale white or light yellow eggs, fertilized eggs hatch at around 19-24°C for 26-29 hours. In recent years, artificially cultivated flowers and lips Oxygen consumption is high, stress is strong, and it is not easy to catch, which restricts its breeding area and promotion speed. [0003] Currently, in how to solve the flower and lips In terms of the shortcomings of high oxygen consumption and strong stress, no effective method has been found yet. Although h...
