Embodiment

[0020] 1. Breeding and selection of broodstock

[0021] 30 days before hatching, select 3 winter-age broodstock, and separate the male and female fish for intensive cultivation. The feed is soybean meal, and the daily feeding amount is 5-8% of the body weight. Selectively mature female fish 100, the abdomen is plump and soft, The mastoid of the genital opening is large and prominent, the hole is round and red, with a total length of 19.22-23.71cm and a weight of 55.96-97.46 g. There are 120 selective mature males, with a total length of 17.89-20.61cm and a weight of 45.11-65.60g. The body is slender and healthy The scales are complete, the operculum of the head is rough to the touch, and semen flows out when the genital opening is gently squeezed, and the semen disperses quickly when it meets water.

[0022] 2. Artificial induced labor

[0023] When the water temperature was constant at 23-25°C, broodstock (female to male ratio: 1:1.2) were selected from the holding pond to i...

Abstract

The invention discloses an artificial reproduction method of chalcalburnus chalcoides aralensis. The artificial reproduction method includes steps of rearing and selecting parent fishes, artificially spawning, inseminating and incubating. The fully-artificial reproduction method which is reasonable, high in operability and massive in production of fry of chalcalburnus chalcoides aralensis is provided, and by optimizing the parent-fish rearing technology and utilizing three different spawning medicines for artificial spawning and inseminating, spawning rate, roe fertility rate and fry incubation rate in parent fish reproduction are increased to 88.2%, 97.0% and 83.64% respectively. The artificial reproduction method is scientific, reasonable and high in operability, industrialized production can be realized by the artificial reproduction method, fry can be provided for large-scale breeding, and high economic benefits are increased.

Description

technical field [0001] The invention relates to an artificial propagation method for freshwater fish, in particular to an artificial propagation method for kala white fish. Background technique [0002] Kara whitefish (Chalcalburnus Chalcoides aralensis) belongs to Cyprinidae, Arroa family, and Calcalburnus genus. The fish has excellent characteristics such as strong stress resistance, wide feeding habits, and good meat quality. It is a rare and rare fish in Central Asia. Kara white fish was originally a wild species, and was introduced into my country for the first time in 2001 by one of the applicants for this patent. [0003] At present, studies on the breeding biology and culture biology of kala whitefish have been reported. The introduction, domestication and breeding of wild fish and pond culture technology have been successful, and achievements have been made in saline-alkali waters and freshwater ponds in my country. However, artificial reproduction has not yet fo...
