Breeding method for increasing survival rate of rana nigromaculata

Abstract

The invention discloses a breeding method for increasing the survival rate of rana nigromaculata. The breeding method comprises the following steps of 1, selection of breeding rana nigromaculata; 2, breeding of the breeding rana nigromaculata; 3, oviposition and fertilization; 4, incubation of rana nigromaculata eggs; 5, breeding management of tadpoles; 6, management of young rana nigromaculata; 7, management of adult rana nigromaculata. The method has the advantages that the oviposition amount is large, the incubation rate is high, egg membrane softening of the rana nigromaculata eggs is effectively avoided, the eggs are prevented from being flat, egg membranes of the rana nigromaculata eggs are prevented from being broken, the incubation rate is 90% or above, the incubation quality is high, the survival rate is high, and the survival rates of the tadpoles, the young rana nigromaculata and the adult rana nigromaculata are all 98% or above. Rana nigromaculata is high in vitality, largein size and good in quality, the color and the taste are improved, the yield of the rana nigromaculata each mu is greatly improved, the growth period is shortened, the breeding cost is reduced, and the economic benefit is improved.

Description

technical field [0001] The invention relates to a breeding method for improving the survival rate of the black-spotted frog. Background technique [0002] The black-spotted frog is a very common frog, belonging to the frog family, anura, and amphibians. The black-spotted frog has tender meat, less fat, low sugar, and high protein content. It has the effects of clearing away heat and detoxification, reducing swelling and relieving pain. The artificial breeding of black-spotted frog is not only simple in technology, but also has fast economic benefits. Therefore, the breeding of black-spotted frog is an aquatic product. Breeding hotspots. [0003] The breeding of black-spotted frogs includes the selection of species of frogs, the cultivation of species of frogs, the fertilization of eggs, the hatching of frog eggs, the raising of tadpoles, the management of young frogs and the management of adult frogs, each of which is very important and will affect The survival rate of bla...

Problems solved by technology

At present, there is a lack of a systematic method for each step in the cultivation of black-spotted frogs. Therefore, in the cultivation process, it is easy to cause low spawning rate, low survival rate of tadpoles, low vitality of black-spotted frogs, and easy to get sick , the survival rate is not high, which eventually leads to the small number of adult black-spotted frogs and poor quality. In addition, in order to improve the survival rate of black-spotted frogs, the production cost in the breeding process is greatly increased, and the economic benefits are not good.
