Table 1 hatches situation contrast table
As can be seen from the above table, traditional to have a native hatching method, either technique or all obviously to fall behind on the time
Method of the invention, Pomacea canaliculata pieces of an egg are placed in an incubator by the present invention simultaneously with eurysome golden thread leech ovum cocoon hatches, young leech
Can be open feed after hatching, carry out opening processing without shifting place for hatching the young leech come, and incubate without soil
Change convenient for observation hatching situation, in terms of survival rate, for the present invention also superior to conventional method, emergence rate is higher, and can reduce
The unnecessary death of young leech is caused in transfer process, pond culture can be transferred to by cultivating 15 days or so in incubator, be not necessarily to
Intermediate incubation simplifies technique, reduces labor intensity.
Through the foregoing embodiment, it can be deduced that：Eurysome golden thread leech hatching opening integrated technique of the present invention, no soil hatching,
Compared to traditional incubation technique, eurysome golden thread leech seedling-growing time is more concentrated, and collection transfer is also more convenient, convenient for management, survival
Rate is higher, while hatching in advance has Pomacea canaliculata in incubator, is directly open after eurysome golden thread leech hatching emergence, reduces culture
Technique saves labour.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although referring to aforementioned each implementation
Invention is explained in detail for example, those skilled in the art should understand that：It still can be to aforementioned each reality
It applies technical solution documented by example to modify, or equivalent substitution of some or all of the technical features；And this
