Method for quick metamorphosis of rana grylio tadpoles

Abstract

A method for quick metamorphosis of rana grylio tadpoles includes steps: (1) increasing change amount of water in a pond to keep water clear and reduce planktons in water; (2) reducing feeding frequency of complete feed from three times to twice a day, and correspondingly reduce feeding amount by half. By adoption of the method, quick metamorphosis of the tadpoles can be realized within 5-10 days, production cycle can be shortened, a young rana grylio period can be kept after metamorphosis, and size uniformity of rana grylio is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of frog breeding, and in particular relates to a method for rapid metamorphosis of American frog tadpoles. Background technique [0002] The American frog is an important economic animal and has many important economic values: American frog meat is not only a rare delicacy, but also has high medicinal value; 1. The high-quality lubricating oil for precision instruments on the rocket, the head, limbs and internal organs of the American frog are high-quality feed, and the American frog is also a good insect catcher and a good helper for crops. In the past, people mainly obtained American frogs from nature. With the development of society, the increase in capture and the deterioration of the growing environment of American frogs, the number of wild American frogs has decreased. In order to meet the growing needs of human beings, for a long time, the source of American frogs mainly depends on artificial breedin...

Problems solved by technology

[0003] Traditional artificial breeding methods, American frog tadpoles generally take about 100 to 120 days to metamorphosis, and the metamorphosis period is correspondingly long, which is not conducive to the breeding of juvenile frogs
