Problems solved by technology

This method mainly solves the problem that the soft-shelled turtles that exist in the prior art have not been selected and bred in each growth period, and the selection strength is not enough, which will mix the defective soft-shelled soft-shelled turtles of each period and the soft-shelled soft-shelled soft-shelled turtles with degraded germplasm, resulting in the breeding of the soft-shelled soft-shelled soft-shelled turtles. , the technical problems of soft-shelled turtle offspring germplasm degradation, quality decline, slow growth, and weakened disease resistance, resulting in low economic benefits

Embodiment 1

[0049] Embodiment 1: The method for breeding fine varieties of Chinese soft-shelled turtle of this example, the steps are:

[0050] a. Choice of ecological environment:

[0051] (1) Environment: Choose a quiet place with sufficient water sources and convenient water intake and drainage to build a pond. The turtle pond needs to be leeward to the sun, so that the turtle can bask and is good for mating;

[0052] (2) Turtle pond specifications: pond area 3000m 2 , The depth of the pond is 1.3m, there are shoals around the pond, the shoal is 15cm from the water surface, and there are no less than 1m for every 30 turtles 2 Basking facilities. Escape prevention facilities are built around the pool; there are independent water inlet and outlet facilities, and barbed wire nets are installed at the water inlet and outlet to prevent escape;

[0053] (3) Spawning ground: There is a spawning ground on the south or north side of the turtle pond, and the terrain is 50cm higher than the maximum w...

Abstract

The present invention relates to a turtle artificial cultivating method, in particular to a method selecting and breeding the good Chinese turtle strain, which resolves the technical problems of the prior art that the turtle is not selected for breeding in different growth periods, the selection of the turtle is not enough to mix the defective turtle in different periods and the quality-degraded turtle, thereby leading to the degradation of the quality of the offspring of the cultivated parent turtle; the quality is reduced, the growth is slowed down and the disease-resistant ability is weakened. The present invention firstly selects the ecological environment and then selects the parent turtle, the fertilized egg, the juvenile turtle, the adult turtle and the reserve parent turtle in turn; wherein, the selection rate of the parent turtle is from eighty percentages to eighty five percentages; the selection rate of the juvenile turtle is from twenty five percentages to thirty five percentages; the selection rate of the adult turtle is from forty five percentages to fifty five percentages and the selection rate of the reserve parent turtle is from sixty five percentages to seventy five percentages.

Description

Technical field [0001] The invention relates to a method for artificial breeding of soft-shelled turtles, in particular to a method for breeding fine varieties of Chinese soft-shelled turtles. Background technique [0002] The conventional breeding of soft-shelled turtle generally adopts the natural breeding method. Turtles are generally hibernating in winter and often cannot lay eggs. The spawning period is only 60 to 80 days a year, and the incubation period of turtle eggs is 60 to 70 days under natural conditions, and the hatching rate is only 20 to 30%. In addition, the newly hatched juvenile soft-shelled turtle weighs only about 4 grams, the foraging period is short, the mortality rate is high under adverse weather conditions in winter, and the growth is extremely slow. Therefore, artificially cultivated turtles have a small number of hatching, low yield and poor quality. , The economic benefits are not good. [0003] The Chinese patent discloses a pollution-free large-size ...
