Stone frogs (definite introduction)
Stone frogs have always been a delicacy on people’s tables. What’s more important is that stone frogs have been listed as national protected animals. Therefore, artificial development has become the key to successfully breeding stone frogs, which can not only meet people's requirements for stone frogs, but also maintain the situation of increasing the number of stone frogs in our country. So where should we start with the artificial growth of stone frogs?
1. Preparation of frog breeding ponds and hatching ponds
Frog breeding ponds and hatching ponds should be built in a dark, quiet place with good water quality, and the area should be 2-3 square meters. . The pool should be thoroughly disinfected and cleaned before being filled with clean water. The water depth should be maintained at about 20 centimeters. It is best to put some stones and fresh aquatic plants.
Two. Breeding and egg-laying
Stone frogs often start mating and laying eggs in April when the temperature is above 20°C. The ratio of male to female frogs is 1:1, and the density is 15-20 pieces per square meter. Breeding frogs usually mate after 21:00 p.m., and female frogs lay eggs between 4:00 and 7:00 p.m. Egg masses often cling to aquatic plants, rocks, and pool walls. Do not stir the eggs within 1 hour after laying, so as not to damage the eggs and reduce the hatching rate.
3. Artificial incubation
Observe and check the frog pond every morning. If there are frog eggs, they can be fished out quietly after 8 o'clock in the morning and placed on the hatching tray in the hatching pond. superior. During the incubation process, there should be some movement of clean water to ensure it is clean. The water temperature should be controlled between 15-30°C, the pH value should be 6-8, and there should be one pool and one nest (500-1000 eggs). Generally, half an hour after laying eggs, the black spots of the fertilized egg ovules become larger, the embryo becomes strip-shaped on day 7, tadpole primordium is produced on day 9, and the membrane breaks to produce tadpoles at dawn on 15 days, with a hatching rate of more than 85%.
