Artificial breeding method of rana nigromaculata

Abstract

The invention discloses an artificial breeding method for rana nigromaculata, and belongs to the technical field of frog breeding. The artificial breeding method comprises the following steps of (1) breeding pond building; (2) seed selection, mating, ovulation and fertilization; (3) tadpole caring; and (4) adult frog catching for marketing. According to the artificial breeding method, the rana nigromaculata is ecologically and industrially bred in a natural ecological environment, the breeding yield of the rana nigromaculata is greatly increased, the rana nigromaculata is conveniently fed by utilizing the controllability of the growth cycle of hermetia illucens larvae, the growth and development of the rana nigromaculata are accelerated due to the rich nutritional value, the disease resistance and stress resistance are enhanced, and the feed cost is reduced; and meanwhile, breeding water in the breeding pond cannot be polluted, real green ecological breeding is achieved, and the methodhas the characteristics of being simple in breeding technology, low in production investment cost, convenient to breed and manage, good in controllability, purely natural, free of pollution and the like, and has wide market prospects.

Description

technical field [0001] The invention relates to the technical field of frog cultivation, in particular to a method for artificial cultivation of black-spotted frogs. Background technique [0002] The black-spotted frog belongs to the frog family. Its meat contains a variety of rich nutrients and has good edible value, and is favored by consumers. Driven by economic interests, the artificial breeding technology of black-spotted frogs is becoming more and more mature. However, the survival rate of artificially cultured black-spotted frogs needs to be improved. Its superb ability to escape has brought greater technical difficulties to the artificial breeding of black-spotted frogs, and there is a large gap between the breeding environment of some farms and the natural environment in which black-spotted frogs grow, failing to form an ecological cycle system, resulting in breeding In the process, the output of black-spotted frogs is not high, thereby reducing the economic benefi...

Driven by economic interests, the artificial breeding technology of black-spotted frogs is becoming more and more mature. However, the survival rate of artificially cultured black-spotted frogs needs to be improved. Its superb ability to escape has brought greater technical difficulties to the artificial breeding of black-spotted frogs, and there is a large gap between the breeding environment of some farms and the natural environment in which black-spotted frogs grow, failing to form an ecological cycle system, resulting in breeding In the process, the output of black-spotted frogs is not high, thereby reducing the economic benefits of farmers. In addition, during the breeding process of black-spotted frogs, we often use fly maggots as feed during the breeding process of black-spotted frogs. The cycle of fly maggots from hatching to adults is very short. Short, it is difficult to control its growth state, which is very unfavorable to large-scale black-spotted frog breeding. If it is fed with feed, it can be quickly cultured in a time much shorter than the production cycle, but the nutritional value is not high, the meat quality is not delicious, water There will be residual haste in the organism, which will seriously endanger the health of the eater
