Quasipaa spinosa tadpole breeding method

Abstract

The invention discloses a Quasipaa spinosa tadpole breeding method and relates to the technical field of Quasipaa spinosa breeding. The method is characterized by comprising the steps of early-stage breeding, wherein feeding is conducted after yolk sacs on the abdomens of newly hatched tadpoles disappear 2-3 days after hatching, cooked egg yokes and soybean milk can serve as initial feed, one egg yoke is fed to 4000 tadpoles each time, and feeding is conducted twice a day; mid-stage breeding, wherein compound feed can be fed 5-7 days later, feeding amount is increased along with the growth of the tadpoles, bait can be directly spread on water, and in general, 800-1000 tadpoles which are 10 days old can be put on each square meter of water for breeding, and 600-800 tadpoles which are 15 days old can be put on each square meter of water for breeding; metamorphosis-period breeding, wherein special metamorphosis-period feed is adopted, and metamorphosis is completed after the tadpoles are fed for 70 days. According to the method, nutrition preparation is reasonable and comprehensive, growth of Quasipaa spinosa tadpoles is facilitated, oxygen can be supplemented, the PH of water can be controlled, the survival rate of tadpoles can reach over 85%, and economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of stone frog breeding, in particular to a method for raising stone frog tadpoles. Background technique [0002] Bamboo stone frog (Quasipaa spinosa) standard name is spinosa, also known as stone clam, rock pheasant, pheasant, stone jelly, flying fish, stone scales, stone toad, stone shrimp, stone pit frog, stone chaos, wooden pagoda tree (South Sichuan) etc., is a kind of animal of amphibian anura order frog family. The stone frog tadpole has a strip-shaped body, a thick tail, dark yellow skin, and small black stars. On the back of the joint between the body and the tail, there is a black "V" pattern. The ability is very strong, and the stone frog is big and strong. Adult frogs generally have a body length of 10-13 cm and a weight of more than 150-250 grams. The large ones can reach more than 500 grams. The skin of the stone frog is rough, the skin on the back is dark gray, and there is a lot of oil on it...

AI Technical Summary

Problems solved by technology

The process of the tadpoles of stone frogs growing into young frogs is the metamorphosis period. At this time, the tadpoles begin to grow limbs and other bones. Therefore, the tadpoles in the metamorphosis period need to eat a lot of substances that are conducive to bone growth and other trace elements such as calcium, phosphorus, and magnesium. , zinc, etc. In the prior art, when adding a large amount of calcium, calcium powder is added, which can supplement sufficient calcium sour
