A kind of domestication of black-spotted frog static food breeding and symbiotic breeding of rice frog

Abstract

The invention provides a rana nigromaculata static predation feeding domestication and frog-rice coexistence cultivation method. The method comprises the following steps of 1, laying bait and a mesh on the upper layer of a rice field ditch; 2, selecting young rana nigromaculata; 3, conducting young rana nigromaculata cultivation; 4, adopting a purifying, rejuvenating, selecting and breeding methodand 5, training static predation. The rana nigromaculata static predation feeding domestication and frog rice coexistence cultivation method prevents a frog habitat from being directly polluted, is beneficial to the healthy growth of frogs and increases the rice planting area, the rana nigromaculata habitat area and the rana nigromaculata putting quantity; a purifying, rejuvenating, selecting andbreeding method is adopted, and in the propagation period every time, and by selecting good rana nigromaculata and through long-term (3-5 generations) domestication, the purpose of improving physiological habits of rana nigromaculata can be achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for domesticating black-spotted frogs with static feeding and symbiotic breeding of rice frogs. Background technique [0002] Black-spotted frog, commonly known as "frog", is one of the common frog species and often appears in rice fields. At the same time, the black-spotted frog devours a large number of insects, and can catch more than 70 insects in one day and night. It is a beneficial animal for eliminating pests in the field. The symbiotic breeding of black-spotted frogs and rice can solve the damage of pests to crops, and is a pollution-free biological method. In contrast to the traditional symbiotic breeding of rice and frogs, a planting model in which a ditch (about 1 meter wide) is generally dug in a paddy field and separated by a ridge of field, and then a bait-casting net is laid on the field. The net is supported by a bracket and separated by a water Ditch and th...

Furthermore, because frogs are accustomed to preying on live food (dynamic food), physical methods are generally used to vibrate the baiting net and some methods are used to drive frogs away from predation. Too many artificially entering and leaving the farm brings a higher risk of germ transmission , resulting in a higher difficulty in the symbiotic breeding of rice and frogs
