Rana spinosa breeding method

Abstract

The invention relates to the field of aquaculture, in particular to a rana spinosa breeding method, which comprises seed selection, spawning, maintaining of tadpole and breeding of froglets and adult frogs. The breeding of froglets and adult frogs comprises construction of breeding ponds, feeding of baits, daily management and regular epidemic prevention. A froglet breeding pond and an adult frog breeding pond are constructed for respective breeding management of the froglets and the adult frogs; feeding is performed with the fixed time, fixed location, fixed quantity and fixed quality to ensure comprehensive nutrients and rapid growth of frogs and reduce diseases of the frogs; an insulation device is set in each breeding pond to increase the temperature of water in the ponds so that frogs can continuously move and eat food without winter sleep, growth of the frogs can be accelerated, and the breeding cycle can be shortened; and the regular epidemic prevention is performed for the breeding ponds with traditional Chinese medicine and disinfectants to prevent diseases of the frogs. By adopting the breeding method, better economic benefits can be achieved, the spawning rate of female frogs is 91.7 percent, the egg fertilization rate is 93 percent, the hatching rate is 96.6 percent, the tadpole metamorphosis rate is 88.4 percent, the froglet survival rate is 90.3 percent, and the survival rate of adult frogs is 93.9 percent after breeding.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating spiny frogs. Background technique [0002] As an emerging agricultural industry, frog aquaculture has a fast development speed and a good prospect. Rana spinosa belongs to the amphibian family Ranaidae. It is a large-scale wild frog unique to my country. It is a national protected animal and a delicacy on people's tables. economic benefits. The spiny-breasted frog belongs to the living type of running water. Generally, it does not eat dead or immobile food. It mainly feeds on insects, centipedes, spiders, and fly maggots. The spiny-breasted frog has been domesticated artificially. Huge changes have taken place. The breeding of spiny-breasted frogs seems simple, but in fact the success rate is not high, which often makes the first-time breeders suffer. The southern provinces have made many attempts in artificial breeding of spiny-breasted frogs in recent years...

The spiny-breasted frog belongs to the living type of running water. Generally, it does not eat dead or immobile food. It mainly feeds on insects, centipedes, spiders, and fly maggots. Huge changes have taken place. The breeding of spiny-breasted frogs seems simple, but in fact the success rate is not high, which often makes the first-time breeders suffer.

In recent years, the southern provinces have made many attempts in artificial breeding of spiny-breasted frogs, but relatively few of them have succeeded and achieved obvious economic benefits; Breeding success
