Embodiment 1

[0032] Such as Figure 1-6 As shown, the present invention provides a kind of loach fishing facility, and it comprises, barrel body 1, and it is hollow inverted cone structure, and the top opening of described barrel body 1, and the bottom is hemispherical and smooth transition with side wall, and described bottom There is a first installation hole 11 that penetrates up and down at the extreme point of the bottom, and the side wall of the bottom is provided with a first hollow part 12 and a second hollow part 12 that are symmetrically arranged. The first hollow part 12 and the second hollow part Filter screens are all provided in the hollow part 12; preferably, the left and right edges of the first hollow part 12 and the second hollow part 12 are all arranged along the meridian direction of the hemispherical shape, and extend upwards until the upper edge of the hemispherical shape contacts, and downwards extending to the edge of the first mounting hole 11, and the area of ​​th...

Embodiment 2

[0041] 1. Pond preparation

[0042] The location of the pond requires flat terrain, clayey soil, sufficient surrounding water sources, no pollution, convenient transportation, and adequate electricity. There are no cracks around the pond and the bottom of the pond, and an independent inlet and drainage system is provided. The top of the pond is covered with a bird-proof net. Prenatal intensive cultivation pond area of ​​1200m 2 , water depth 0.85m, silt depth 17cm; postpartum restoration and cultivation pond area 800m 2 , water depth 0.85m, silt depth 17cm; overwintering cultivation pond area 1000m 2 , the water depth is 1.35m, and the silt depth is 25cm.

[0043] 2. Parent selection

[0044] Select the 2-year-old loach with strong physique, normal body color, healthy and lively, no injury and disease as the parent. The body length of the male loach is 15-18cm, the body length of the female loach is 12-15cm, and the ratio of male to female is 3:1.

[0045] 3. Parental cul...

Embodiment 3

[0054] Pond conditions, parental selection and parental cultivation are the same as in Example 2, except that the fermented peanut bran used in fertilizer and water is prepared by the following steps, adding 12 parts by weight of EM bacterium liquid and 15 parts by weight of peanut bran to 100 parts by weight of peanut bran. After mixing the water in parts by weight, pile it up for fermentation. When the temperature in the pile exceeds 70°C, turn it upside down. In the later stage of fermentation, when the temperature inside the pile does not exceed 70°C, turn it upside down every 2 days until it is fermented to peanuts The bran is deep in color and soft; wherein, the EM bacteria solution is prepared by inoculating 3 parts by weight of EM bacteria into 100 parts by weight of brown sugar water with a mass concentration of 10%, mixing well, and sealing and fermenting for 5 days.

Abstract

The invention discloses a paramisgurnus dabryanus parent cultivation method. The paramisgurnus dabryanus parent cultivation method comprises the following steps of selecting 2-year or more loaches which are strong in physique, normal in body color, healthy, lively and free of injuries and diseases as parents, wherein the body length of the male loaches is more than 15 cm, the body length of the female loaches is more than 12 cm, and the male-female ratio is 3: 1; and respectively carrying out prenatal intensified cultivation in two months before delivery in spring and autumn, carrying out postnatal repair cultivation in one month after delivery, and carrying out overwintering cultivation before winter. The paramisgurnus dabryanus parent cultivation method has the advantages that the deathrate of the parent loaches after artificial insemination can be reduced, and spring and autumn breeding of the parent loaches is achieved.

Description

technical field [0001] The invention relates to the field of loach breeding. More specifically, the present invention relates to a method for cultivating parents of Paraloach chinensis. Background technique [0002] Paraloach is a fish belonging to the genus Paraloach in the Loach family. It is commonly known as Big Loach and is a unique species in China. The breeding method of Paraloach is mainly artificial breeding, and the research focus of the existing artificial breeding method is mainly concentrated on improving the survival rate of larvae breeding, ignoring the research on the parental breeding of loach. Contents of the invention [0003] An object of the present invention is to provide a method for cultivating the parents of Paraloach, which promotes the development and maturation of the gonads of the parent loach and improves the disease resistance of the parent loach , reduce the mortality rate of pro-loach after artificial insemination, and realize the breedin...
