Embodiment 1

[0053] A kind of loach of the present embodiment and the method for hybrid breeding of paraloach with large scales, described method comprises the steps:

[0054] (1) parental pool preparation

[0055] Choose a place with convenient transportation, sufficient water sources, quiet environment, good water quality, neutral or slightly acidic soil, loess or loam soil to build loach and paraloach parent ponds, with an area of ​​2 to 3 mu, pond depth of 1.0 to 1.5m, and water level maintenance. About 0.8m, the depth of silt at the bottom of the pool is about 20cm, a drainage system is installed, the water inlet is about 30cm above the water surface, and the inlet and outlet are equipped with anti-escape filters.

[0056] (2) Clear pond

[0057] Before stocking the parents, disinfect with quicklime water (about 15cm) at a dosage of 100 catties / mu. After 5 days, inject new water to a depth of about 0.8m.

[0058] (3) Delivery

[0059] Loach parent specifications: local loach in Yic...

Abstract

The invention discloses and relates to a loach and paramisgurnus dabryanus hybrid breeding method and belongs to the technical field of aquaculture. The loach and paramisgurnus dabryanus hybrid breeding method comprises the following steps of parent breeding, pond management, artificial insemination and hatching, and seedling cultivation. The loach and paramisgurnus dabryanus hybrid breeding method can improve the survival rate of loach seedlings; a first-filial generation with Taiwanese paramisgurnus dabryanus as male parent and domestic green loach as the female parent is high in fertility rate, hatching rate and survival rate, quick in growth and similar to the domestic green loach in body form, color and taste.

Description

technical field [0001] The invention belongs to the technical field of aquaculture. Specifically, the invention relates to a method for hybrid breeding of loach and paraloach. The method of the invention can improve the survival rate of loach seedlings. Background technique [0002] Loach is a small special economic fish with small head, few spines and good taste. Loach has high nutritional and medicinal values, and enjoys the reputation of "ginseng in water" and "soft gold". Its health-preserving and therapeutic functions have gradually been recognized by the public. Due to the different places of origin and living environments, the quality of loach also has certain differences. The indigenous loach species in my country mainly include loach and paraloach. The former has an ideal body shape and color, and has a better taste, while the latter has a faster growth rate and stronger disease resistance. Due to the characteristics of fast growth, low bait coefficient, strong di...
