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.

Abstract

The invention discloses a breeding method of rana nigromaculata. The breeding method comprises the following steps of 1, parent frog selection; 2, parent frog breeding; 4, frogspawn hatching; 5, tadpole breeding management; 6, young frog management; 7, adult frog management. According to the breeding method of rana nigromaculata, the frogspawn yield is large, the hatching rate is high, egg membrane softening and egg flattening of frogspawn are effectively avoided, egg membranes of the frogspawn are prevented from being broken, the hatching rate is 90% or above, the hatching quality is high, the survival rate is high, and the tadpole survival rate, the young frog survival rate and the adult frog survival rate are all 95% or above. The rana nigromaculata is strong in vitality, large in sizeand good in quality, the color and the taste are improved, the yield of the rana nigromaculata per 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 method for cultivating black-spotted frogs. 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 black-spotted frog and the quality...
