Ecological collection method of giant spiny frog eggs

Abstract

The invention discloses an ecological collection method of giant spiny frog eggs. The ecological collection method comprises the following steps: putting a plurality of frog egg collection plates into an egg laying water tank of a seed frog pond; taking out the frog egg collection plates on which eggs are attached after seed frogs lay eggs, and collecting the frog eggs. The structure of the seed frog pond is a rectangular pond; a water inlet and a water outlet are formed in a pond wall; the egg laying water tank is arranged along the pond wall of the seed frog pond; an area enclosed by the egg laying water tank is a seed frog living area; a plurality of bosses are arranged in the seed frog living area; water ditches are formed between adjacent bosses; cobblestones are paved on the bosses; plants are planted on the bosses; aquatic plants are planted in the water ditches; a plurality of omnivorous freshwater fishes are put and bred in each water ditch. Through the ecological collection method, the original ecology living environment of giant spiny frogs is simulated by manners of piling cobblestones, planting aquatic and terrestrial plants and discharging water from a high position to make running water and water sound; the seed frogs are induced to rut, mate and ovulate; the egg laying water tank is isolated from the seed frog living area; the ecological collection method has the characteristics of low interference, high quantity, high fertilization rate and high hatchability.

Description

technical field [0001] The invention relates to an ecological collection method of spinosa spinosa eggs, belonging to the technical field of aquaculture. Background technique [0002] As the saying goes, "there are forest frogs in the north and stone frogs in the south", and the stone frogs (Rana spinosa) are of great development value. The spiny frog naturally likes to live in an environment with high mountains and streams, and the area where it is distributed represents the quality of the natural environment in the area. The traditional selection of breeding sites for spiny-breasted frogs is not strict enough, basically belongs to workshop-style farming, and the output is low. In addition, the current research on spiny-breasted frogs is relatively scarce. There is no uniform standard in the construction of frog ponds and the environmental selection of species of frogs. The wild germplasm resources are mainly caught. In addition, in the collection of frog eggs, it is mai...

In addition, the current research on spiny-breasted frogs is relatively scarce. There is no uniform standard in the construction of frog ponds and the environmental selection of species of frogs. Catch wild germplasm resources mainly

In addition, in the collection of frog eggs, it is mainly to place the spawning board (mainly wooden board) in the frog pond, take it out after the frogs have laid eggs, and scrape off the eggs before hatching. This kind of manual collection of frog eggs The method is not only cumbersome to operate, but also the natural hatching success rate of frog eggs is low, less than 50%. During the day, the eggs are taken to open the spawning plate, which will cause a greater stress response to the frogs hiding here
