Problems solved by technology

[0004] The biggest problem existing in existing frog breeding is that the survival rate is high in the tadpole stage, and in the process of developmental metamorphosis, it is easy to occur that metamorphosis cannot be completely carried out, the mortality rate is high, and problems such as deformities are prone to occur. This has nothing to do with the environment and the breeding method. there are bigger reasons

Embodiment 1

[0017] A method for improving the survival rate of frog breeding metamorphosis, comprising the following steps:

[0018] (1) Select a natural pond with 60% coverage of aquatic plants and water quality that is not polluted as the parent frog spawning pond, and release the parent frogs at a ratio of 1.5:1 male to female, with 2 frogs per square meter of water area. Remove the natural enemies of the frogs in the pond beforehand, and keep the surroundings of the pond quiet when hugging the frogs. After spawning, use a sunshade net to cover the aquatic plants exposed to direct sunlight. Tadpoles can be caught in artificial breeding ponds 20 days after hatching feeding;

[0019] (2) Build an artificial breeding pond in the rice field, and set up a breeding ditch with a width of 1.5 meters in the breeding pond. The waters at both ends of the ditch are connected. On a gentle slope of rice, bamboo poles are inserted diagonally between the gentle slopes, and loofahs are planted on the ...

Embodiment 2

[0025] A method for improving the survival rate of frog breeding metamorphosis, comprising the following steps:

[0026] (1) Select a natural pond with unpolluted water quality and 65% coverage of aquatic plants as the parent frog spawning pool, and release the parent frogs at a ratio of 1.7:1 for male and female, with 2 frogs per square meter of water area. Remove the natural enemies of the frogs in the pond beforehand, and keep the surroundings of the pond quiet when hugging the frogs. After spawning, use a sunshade net to cover the aquatic plants exposed to direct sunlight. Tadpoles can be caught in artificial breeding ponds 22 days after hatching feeding;

[0027] (2) Build an artificial breeding pond in the rice field, and set up a breeding ditch with a width of 1.6 meters in the breeding pond. On a gentle slope of rice, bamboo poles are inserted diagonally between the gentle slopes, and loofahs are planted on the gentle slopes, and the loofah vines are wrapped around th...

Embodiment 3

[0033] A method for improving the survival rate of frog breeding metamorphosis, comprising the following steps:

[0034](1) Select a natural pond with 70% coverage of aquatic plants and water quality that is not polluted as the parent frog spawning pond, and release the parent frogs at a ratio of 2.0:1 for male and female, with 3 frogs per square meter of water area. Remove the natural enemies of the frogs in the pond beforehand, and keep the surroundings of the pond quiet when hugging the frogs. After spawning, use a sunshade net to cover the aquatic plants exposed to direct sunlight. Tadpoles can be caught in artificial breeding ponds 25 days after hatching feeding;

[0035] (2) Build an artificial breeding pond in the rice field, and set up a breeding ditch with a width of 1.8 meters in the breeding pond. The waters at both ends of the ditch are connected. On the gentle slope of rice, bamboo poles are inserted obliquely between the gentle slope and the gentle slope. On the...

Abstract

The invention relates to the technical field of frog breeding, and discloses a method for increasing the survival rate of the frog breeding metamorphosis stage. The method comprises the following steps that 1, a natural pond is used as a frog spawning pond, the spawning quality of frogs can be improved, fertilized eggs can be suitable for temperature variation of a pond and can be attached to water plants, the hatching speed is increased conveniently, hatched tadpoles can take a large amount of plankton in the pond, and the vitality of the tadpoles is improved; 2, an artificial breeding pond is constructed in a rice field, the tadpoles stable in development are put into the rice field for breeding, the condition setting inside the breeding pond is good in ecological balance, less manual intervention exists, a natural environment can be created for metamorphosis development of the tadpoles, and the metamorphosis survival rate is increased; 3, the feeding amount and feeding feed play an important role in development and growth of the tadpoles in the transition period to the metamorphosis stage, and by means of the feed high in protein and rich in vitamins and minerals, metamorphosis development can be conducted normally.

Description

technical field [0001] The invention belongs to the technical field of frog breeding, and in particular relates to a method for improving the survival rate of frog breeding during metamorphosis. Background technique [0002] Frogs are amphibious economic animals. They used to be very common in rice fields in vast rural areas. Hearing chickens and dogs and singing frogs are symbols of pastoral life; After harvesting, the number of winter paddy fields has been greatly reduced. Under the influence of human disturbance, poor protection and deterioration of the living environment, there are fewer and fewer frogs in nature. Frog farming was developed under the guidance of adjusting the structure of aquaculture and vigorously developing famous, special, high-quality, and indigenous aquaculture policies. After nearly 10 years of exploration, testing and summarization, the technology of frog breeding and domestication has gradually matured, and the scale of farming has gradually matu...
