Embodiment Construction

[0025] The present invention is further described below in conjunction with the examples, but the enumeration of the examples is only to further explain the technical solutions of the present invention, to facilitate understanding, and the protection scope of the present invention is not limited thereto.

[0026] The artificial breeding method of a kind of red-tailed loach fry provided by the invention comprises the following steps:

[0027] 1) Breeding of broodstock: special ponds with flowing water are used for cultivation, with an area of ​​20-50 m 2 , the water source conditions are good, the water quality is fresh and pollution-free, and the water volume is sufficient; artificial caves are set up to facilitate the broodstock to inhabit when the sun is strong; the first 3 to 4 days before the broodstock is stocked, soak in 5ppm chlorine dioxide or 20ppm povidone-iodine solution for 24h, and then Clean and put into natural river water, the water level is 70-100cm; stocking ...

Abstract

The invention relates to an artificial propagation method of fry of paracobitis variegatus. The artificial propagation method comprises the steps of parent fish rearing, parent fish selection and mating, artificial spawning, fertilization, oosperm hatching, larva fish temporary rearing and fry rearing. The artificial reproduction technology of the paracobitis variegates is successfully summarized in the artificial propagation method, and the artificial propagation method fills the blank of the technology. By adopting and popularizing the artificial propagation method having been successfully studied out, the fry of the paracobitis variegatus can be obtained in batches in a centralized mode, the spawning rate, the fertilization rate and the hatching rate are high, and large-scale production of the paracobitis variegatus can be easily achieved. Thus, the artificial propagation method has great significance on protection and large-scale rearing of the paracobitis variegatus wild resources.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an artificial breeding method for red-tailed loach fry. Background technique [0002] The red-tailed loach belongs to the genus Paraloach of the family Cypriniformes, Loachidae, and is distributed in the headstream of the tributaries of the Han River, the Duhe River, the Yandu River, the Jinsha River, and the Nanpan River, a tributary of the Yangtze River; small fish, generally 10-17cm in length , a bottom-dwelling life, and likes to live in rock crevices, rock crevices or backwater bays with many boulders. [0003] Red-tailed loach is a rare fish and a high-quality fish species in the production area. Its meat is tender, delicious, and nutritious. It is deeply loved by consumers and has great economic value and ornamental value. In recent years, with the severe fragmentation of the ecosystem in the water area of ​​origin, coupled with the construction of water c...
