Problems solved by technology

Therefore, it is technically required to use targeted strategies for breeding broodstock of loach in mountainous areas. At the same time, through the conclusion of artificial breeding experience for many years, it is inappropriate to apply the breeding technology of loach from other provinces mechanically for the breeding of loach in mountainous areas.

Embodiment 1

[0020] This example was carried out at the Xiuwen loach nursery base of Guizhou Qiuxing Aquatic Products Co., Ltd. from 2015 to 2016. The specific steps are as follows:

[0021] 1. Cultivation of parent loach

[0022] (1) Parent loach selection: From August to September 2015, according to the specification, 8-10 tails per kilogram, the total length of the female parent loach is 25-27cm, and the individual body weight is 100-120 grams. The total length of the male parent loach is 27-30cm, and the individual body weight 80-100 grams, selected parent loach with a male to female ratio of 4:1.

[0023] (2) Feed feeding: From October 2015 to February 2016, male and female broodfish were manually selected and cultivated in separate ponds. The size of the breeding pond was 25m long x 8m wide x 1m deep, and the stocking density was 250-300 per mu. kg, carry out nutrient-intensive cultivation to the parent loach, and feed high-protein feed during the cultivation period, and feed the fe...

Embodiment 2

[0037] Refer to attached figure 1 and figure 2 , the present embodiment provides a kind of hatching system for loach fry, comprising reservoir 1, water pump 2 and hatching tank 3, animal tank 1 is used for hatching water precipitation disinfection, provides all hatching tanks hatching water and circulation, each reservoir 1 is correspondingly provided with a plurality of hatching tanks 3, the bottom of the hatching tank 3 is provided with a hatching drain 31, and an impurity filter is arranged at the hatching drain 31, and the hatching drain 31 extends into the reservoir 1 through a water supply pipeline, so The water pump 2 is arranged on the water supply pipeline, and one end of the water inlet pipe 4 is provided with a nozzle 41 and extends into the hatching tank 3. The bottom of the hatching tank 3 is a 120-degree flat arc, and the nozzle 41 is relatively parallel to the bottom of the hatching tank 3, so that fertilization There is no dead angle in the water body exchang...

Abstract

The invention provides a mountainous area loach parent cultivation and artificial induce spawning method, and an incubation system. The mountainous area loach parent cultivation and artificial induce spawning method includes the following steps: selecting loach parents, and breeding the female loach parents and male loach parents in different pools; performing long water flow stimulation to enhance gonad development one month before a mating season; dissolving 400-500 IU/kg fish chorionic gonadotrophin HCG and 6-8 ug/kg luteinizing hormone releasing hormone LHRH_A2 in 4-5 mg/kg domperidone DOM to be used as an inducing agent; collecting mature sperms and eggs in a period after induce spawning; and using a dry method and a semi-dry method to perform artificial insemination. The problem of the quality of loach parent cultivation in mountainous area pool resource characteristics can be solved; a mountainous pool loach artificial cultivation and high efficiency reproduction flow is formed so as to perfect the prior art, and the breeding benefits can be increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural aquaculture, and in particular relates to a method for parental cultivation and induced production of loach in mountainous areas. Background technique [0002] Loach is a traditional famous and high-quality aquatic product, which is widely distributed all over the country, especially in rice fields and ponds in the south where there is water all the year round. The unique geographical and climatic conditions of Guizhou Province are very suitable for the cultivation of loach. At present, artificial breeding of loach in the province has become one of the ways for farmers to get rich. Guizhou's karst landform is mountainous and gully and rich in water resources. Many farmers have wild loach in the rice fields. This shows that the climatic conditions in the mountainous areas of Guizhou are suitable for the growth of loach. Over the years, Guizhou Qiuxing Aquatic Products Co., Ltd. has explored t...
