specific Embodiment approach 1

[0007] Specific embodiment 1: The nesting method of Xingkai's cocked-mouthed red bream in this embodiment is realized according to the following steps: the cocked-billed red bream with a single tail length of 4 to 10 cm is placed in a pond where the water temperature is 6 to 36°C and the pond area is 3 ~25 mu and the pond depth is 1.2~5.0m for interbreeding; among them, red carp with cocked mouth can be nested with silver carp, silver carp and carp, or red carp with cocked mouth can be raised with silver carp and lip Set up with Dinggui fish, or cocked red carp with silver carp, lip Nested with yellow mulberry, or nested with bream, silver carp, silver carp, black carp and crucian carp.

specific Embodiment approach 2

[0008] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the length of a single tail of the scalloped red carp is 6-8 cm. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0009] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the length of the single tail of the cocked-billed red carp is 7cm. Other steps and parameters are the same as those in Embodiment 1.

Abstract

A polyculture method of an erythroculter ilishaeformis (Bleeker) relates to a fish polyculture method. The method solves the problems of low survival rate and slow growth in the existing artificial reproduction method of the erythroculter ilishaeformis (Bleeker). The polyculture method is characterized by polyculturing the erythroculters ilishaeformis (Bleeker) with an individual length ranging from 4cm to 10cm in a pond with the area of 3-25mu and a depth of 1.2-5.0m at the temperature of 6-36 DEG C. The polyculture method not only improves the survival rate of the erythroculters ilishaeformis, but also improves the survival rate of the polycultured fish varieties, and the erythroculters ilishaeformis and the polycultured fish varieties grow quickly.

Description

technical field [0001] The invention relates to a method for nesting fish. Background technique [0002] Commonly known as big white fish, cocked mouth, cocked shell, white silk, Xingkai big white fish, cocked carp, stinging fish, cocked white, white fish, pouting carp, etc., are distributed in major water systems across the country. Xingkai red bream is a subspecies of red bream. It is only distributed in Xingkai Lake, Heilongjiang. It is one of the four famous freshwater fishes in China. It is large and long and can weigh tens of kilograms. It has the taste of crabmeat, and the fish soup is as white as milk; however, due to the increasingly harsh natural environment and serious water pollution, the output of Xingkai’s red carp is declining year by year, and the market price is as high as more than 300 yuan per kilogram; natural resources It has been unable to form a group yield, and has even reached a state of depletion. It is imminent to develop the artificial breeding o...
