Rana nigromaculata and rice symbiotic planting and breeding method

Abstract

The invention discloses a rana nigromaculata and rice symbiotic planting and breeding method, which comprises the following steps: S1, rice field selection, region division and transformation, S2, parent selection and breeding, and S3, adult frog fishing and rice harvesting, and also discloses a specific management method of a breeding pond, a hatching pond, a nursery pond and a breeding pond, which comprises the steps of regulating and controlling the area proportion of each region, and managing the breeding pond, the hatching pond, the nursery pond and the breeding pond. The feeding proportion and density of parents, egg masses, tadpoles and froglets in the breeding pond, the hatching pond, the nursery pond and the culture pond are strictly regulated and controlled, the water level and water quality are strictly regulated and controlled according to climate characteristics in different periods, micro-running water equipment is erected in the hatching pond to improve the water quality, increase the dissolved oxygen and the like, the rana nigromaculata culture density can be effectively controlled, the rice field space is efficiently utilized, and the yield of rana nigromaculata is increased. According to the method, the rana nigromaculata can be bred in advance to form ordered breeding and controllable production, so that the rana nigromaculata can come into the market in advance, high-quality and large-specification rana nigromaculata can be bred, the specification of 80% of commercial rana nigromaculata can reach 40 g or above, and therefore the method has higher economic benefits.

Description

technical field [0001] The invention belongs to the technical field of black-spotted frog breeding, and in particular relates to a method for symbiotic planting and breeding of black-spotted frogs and rice. Background technique [0002] Rice field ecological planting is a production mode that uses the ecological space of rice fields to cultivate fish, shrimp, loach, soft-shelled turtles, frogs and other aquatic or amphibians in rice fields by symbiosis or crop rotation. In the traditional rice field planting system, people over-harvest the naturally growing rice field frogs to let the frog meat enter the dining table, which leads to a sharp decrease in the number of frogs in the rice field ecosystem, resulting in an increase in the number of rice field pests. In order to prevent pests and diseases, farmers abuse pesticides and further reduce the The number of frogs that grow naturally in the rice field system has been destroyed, causing damage to the balance of the rice fiel...

Problems solved by technology

Solve the existing black-spotted frog breeding mode that integrates breeding and propagation, which may easily cause the breeding density of black-spotted frogs to be difficult to control, and cannot accurately put in breeding supplies, which will lead to deterioration of water bodies, surge of diseases, loss of input costs, etc., and will also affect commercial frogs. specifications and quality issues
