The breeding technology of stone frogs

Whenever the spring water temperature exceeds 15°C, stone frogs begin to breed. Under normal management conditions, frogs weighing more than 200 g can lay their eggs twice, mainly in April-May and July-August. Each pair of ovulation can reach 1000-2000 capsules at a time. Spawning volume varies with individual size, water temperature, and gonadal development. The egg is a sticky egg, and the egg is thin, and the sheet is mostly adhered to the side wall of the stone or pool. After 10-15 days, it hatches into a cocoon.
In the April-September breeding season, reproductive mating generally runs from 9 pm to 3 am the next day. Must be selected as a parent with a body weight of 200 grams or more as a parent and colonized in a spawning pool. Drop density is generally 1 to 2 pairs per square meter, female to male ratio is 1.5:1. The male frog discharges sperm while the female frog spawns. After the frog eggs are transferred to the hatchery pond, care should be taken that the water quality is clean, the water temperature does not exceed 30°C, and the density should not be too large. Normal water temperature at 26 ~ 32 °C, from fertilization to hatching seedlings, generally takes 240-290 hours. The length of the incubation period is greatly affected by the temperature of the water, the water temperature is high, and the incubation period is short; otherwise, it is longer. The fertilization rate is about 88%, and the hatching rate is about 72%. The newly hatched quail has its yolk sac as a nutrient source within 4 to 5 days; when the yolk sac is consumed, it begins to feed. It is better to feed it by hand or more in the afternoon. Can feed some of the higher protein bait, such as egg yolk, soy milk and fish meal. The water in Dianchi Lake should be fresh and clean. Because the pupa is buzzing, if the pool water deteriorates, stinks or bubbles, it can easily cause inflammation of the cerumen and death. Therefore, the water must always be kept fresh and clean.
