Stock breeding method of frogs

Abstract

The invention discloses a stock breeding method of frogs. The stock breeding method comprises the following steps: a, management before breeding: before breeding, greenhouse cement ponds including a parent frog culture overwintering pond, a spawning pond and a tadpole culture pond respectively, disinfection is carried out before use, the insides of greenhouses are thoroughly cleaned, and fumigation or spray disinfection is performed thoroughly after the greenhouses are dried in the sun; and b, parent frog culture: the stocking density of parent frogs and the male-female ratio are guaranteed, sufficient activity ranges, proper temperature and clean environments for the parent frogs are ensured, and the measures such as thermal insulation and water temperature increase are taken to short thehibernation period of the parent frogs, prolong the growth and development period and promote gonad development to achieve the purpose of early propagation. The stock breeding method has the beneficial effects as follows: excellent verities are selected for culture of the parent frogs, the parent frogs are fed with good bait, good development environments are provided, so that the parent frogs produce spawns with the highest quality, the optimal growth environment and the optimal bait are provided in the process that small frogs grow from spawns, tadpoles to adult frogs, and the frogs can grow healthily and rapidly.

Description

technical field [0001] The invention relates to the technical field of frog breeding, in particular to a method for breeding fine frogs. Background technique [0002] Frogs belong to the amphibians of the Chordate Phylum, Amphibians, Anura, and Ranaidae. Adults have no tail, eggs are laid in water, fertilized in vitro, hatched into tadpoles, breathe with gills, and after mutation, adults mainly breathe with lungs , and use the skin to breathe. Most frogs reproduce through in vitro fertilization, and the fertilized eggs hatch into tadpoles outside the mother's body. Because frogs feed mainly on insects and other invertebrates, they must live near water. There are about 130 species of frogs in China, and almost all of them are experts in eradicating forest and farmland pests. [0003] At present, due to the large number of human beings who do not kill and eat frogs, the number of them has dropped sharply, and it has been listed as a national second-class key protected animal...
