A kind of artificial culturing method of three way cross soft-shelled turtle kind
Technical field
What the present invention relates to is a kind of artificial culturing method of three way cross soft-shelled turtle kind, belongs to artificial and supports soft-shelled turtle technical field.
Background technology
It is quite ripe that current pond ecological supports soft-shelled turtle technology, and it specifically comprises: pond condition and cleaning up the pond, and seed is put in a suitable place to breed, feeding and management, results etc.; The soft-shelled turtle that can cultivate is supplied to market, and obtain good economic benefit, this is the wish of each raiser, but reach aquaculture cost to reduce, the objects such as the survival rate height of finished product soft-shelled turtle, the cultural technique not only needed, good factor of natural environment, the also necessary soft-shelled turtle kind having quality good, but what existing ecology supported that soft-shelled turtle technology selects substantially is unitary soft-shelled turtle, as Taihu Lake Shelled Turtle Trionyx Sinensis, Taihu Lake crow soft-shelled turtle, and Japan is soft-shelled turtle etc., the resistance against diseases of this unitary soft-shelled turtle kind is low, high temperature resistance low temperature tolerance ability is weak, poor quality, and feed coefficient is high.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and a kind of improvement carried out on the basis of existing soft-shelled turtle cultural technique is provided, improve resistance against diseases and the high temperature resistance low temperature tolerance ability of soft-shelled turtle, the quality of finished product soft-shelled turtle is improved greatly, the artificial culturing method of the three way cross soft-shelled turtle kind that feed coefficient is low.
The object of the invention is to have come by following technical solution, the artificial culturing method of described three way cross soft-shelled turtle kind, it comprises the steps:
A, pond are selected, the pond of more than 3 mu, depth of water 70-90 centimetre, and the surrounding in pond is carried out the anti-of routine and escaped measure, and the field of laying eggs of 3-8 square metre is built on limit, pond;
B, binary are put in a suitable place to breed: March 15, every mu of Taihu Lake China more than 500 grams of the ratio stocking size according to 5:1 to be female soft-shelled turtle and Japan be male soft-shelled turtle 300-500 only to April 15;
C, bait of throwing something and feeding, late April, start the fresh foods such as trash fish of throwing something and feeding, and feeding volume is determined by the body weight 2-3% of soft-shelled turtle; The 6-8 month.Bait feeding amount increases to the body weight 5-8% of soft-shelled turtle, starts June to produce two-way cross egg;
D, binary soft-shelled turtle kind cultivating and managing, the 4-9 month, every 1 to 2 month with disinfection agent of chlorine dioxide diseases prevention once, every mu of consumption 150-250 gram;
E, ternary are put in a suitable place to breed, the female soft-shelled turtle of hybridization of more than 3 years and the male black soft-shelled turtle in Taihu Lake again mixed put together with hybridize, obtain three way cross soft-shelled turtle;
F, ternary put in a suitable place to breed after bait feeding put in a suitable place to breed with cultivating and managing and binary after substantially identical.
The present invention is first female soft-shelled turtle and Japan with Taihu Lake China is that male soft-shelled turtle hybridizes, and obtains two-way cross soft-shelled turtle; Hybridize with the male black soft-shelled turtle of the female soft-shelled turtle of two-way cross soft-shelled turtle and Taihu Lake, draw three way cross soft-shelled turtle, be called for short " hybridization soft-shelled turtle "; It has the resistance against diseases and high temperature resistance low temperature tolerance ability that improve soft-shelled turtle, makes the features such as the quality of finished product soft-shelled turtle improves greatly, and feed coefficient is low.
