A kind of artificial breeding method of three-element hybrid soft-shelled turtle species

Abstract

Disclosed is an artificial cultivation method of three-way-cross soft-shelled turtle species. The method includes the following steps that firstly, a pond is selected in the form that a pond more than 3 mu in area and 70 cm-90 cm in water depth is selected, conventional escape preventing measures are well taken corresponding to the periphery of the pond, and a 3m<2>-8m<2> egg laying field is built by the side of the pond; secondly, two-way breeding is carried out in the form that from March 15 to April 15, three hundreds to five hundreds Tai Lake Chinese female soft-shelled turtles and Japanese male soft-shelled turtles which are respectively heavier than 500g are put to be bred according to the proportion of 5:1 per mu; thirdly, bait feeding is carried out in the form that during the last ten-day period of the April, fresh and alive baits like trash fishes start to be fed with the feeding amount determined by 2%-3% the weights of the soft-shelled turtles, from the June to the August, the feeding amount of the baits is increased to 5%-8% the weights of the soft-shelled turtles, and two-way-cross eggs start to be laid from the June; fourthly, two-way soft-shelled turtle cultivation management is carried out in the form that from the April to the September, chlorine dioxide sanitizers are used for preventing diseases once every one to two months with the dosage of 150 g-250 g per mu; fifthly, three-way breeding is carried out in the form that more-than-three-year cross-fertilized female soft-shelled turtles and Tai Lake male soft-shelled turtles are mixed together to be cross-fertilized again to obtain the three-way-cross soft-shelled turtles; sixthly, bait feeding and cultivation management after three-way breeding are substantially the same as those after three-way breeding.

Description

Technical field [0001] The invention relates to an artificial breeding method of a ternary hybrid turtle species, belonging to the technical field of artificial turtle breeding. Background technique [0002] At present, the technology of ecological turtle breeding in ponds is quite mature. It specifically includes: pond conditions and clearing of ponds, seed stocking, breeding management, harvesting, etc.; good turtles can be raised to the market and good economic benefits are obtained. The wish of farmers, but to achieve the goal of reducing breeding costs and high survival rate of finished soft-shelled turtles, not only good breeding techniques and good natural environmental factors are required, but also good-quality soft-shelled turtle species are necessary, but the existing ecological turtle breeding The technology basically uses univariate soft-shelled turtles, such as Taihu Chinese soft-shelled turtles, Taihu black soft-shelled turtles, and Japanese type soft-shelled turtl...

AI Technical Summary

Problems solved by technology

[0002] At present, the technology of pond ecological breeding of soft-shelled turtles is quite mature, which specifically includes: pond conditions and clear ponds, stocking of seedlings, breeding management, harvesting, etc.; the soft-shelled turtles that can be bred can be provided to the market and obtain good economic benefits. The wish of farmers, but to achieve the purpose of reducing breeding costs and high survival rate of finished soft-shelled turtles, not only good breeding techniques, good natural environmental factors, but also good-quality soft-shelled turtle species are necessary. Basically, the technology is selected from the unary soft-shelled turtle, such as Taihu Chinese soft-shelled turtle, Taihu black soft-shelled turtle, and Japanese soft-shelled soft-shelled turtle.
