CATDOLL : CATDOLL: What are the stone frog breeding techniques and site construction?

Site construction:

1. Frog breeding pond: The area is generally 4 to 10 square meters, the pond is 0.8 meters high, the water depth is 0.1 to 0.15 meters, the water-land area ratio is 3:1, and there are stone caves for habitats. The bottom of the pond is paved with large pebbles. The light is dim and the humidity is maintained at 80%, creating an ideal ecological environment for stone frogs to live, promote their growth and development, and thus increase the egg-laying rate and fertilization rate.

2. Hatching pool: area 1 square meter, pool height 0.5 meters, water depth 15-20 centimeters, fresh water, pH 6-8, and sufficient oxygen. You can also use a long oval basin instead.

3. Tadpole pond: area 3-8 square meters, pool height 0.8 meters, water depth 3-10 centimeters, pH 6-7, water-land ratio 2:1, requires shade for breeding, and it is better to raise a group of tadpoles of the same size in each pond.

4. Frog pond: area of ​​4 to 6 square meters, pool height of 0.8 meters, water depth generally 10 to 15 centimeters, water-to-land ratio of 2:1, 3 to 5 centimeter pebbles are laid in the pool, there are stone holes, the water quality is good, pH value is 6 to 7.5.

5. Other requirements: All kinds of frog ponds for stone frogs are preferably rectangular in shape, with a slightly inclined bottom and the drainage hole at the lowest point so that the water can be completely drained. The pond should be equipped with water surface, land, stone caves, feeding tables, etc. A net cover should be installed at the top of the pond to prevent frogs from jumping and escaping and invasion by harmful organisms. The water inlet pipe should be installed on the top of the pond, close to the bottom of the net cover. Newly built ponds cannot be used immediately and should be disinfected with disinfectant (to remove alkalinity) and rinsed with water several times before raising frogs.

Breeding technology:

1. Selection of breeding frogs: Selecting breeding frogs is the basis for good artificial breeding. After hibernation and before spring breeding, the adult frogs should be comprehensively inspected and classified, and the adult frogs that are larger, stronger, have smooth skin, are well developed, have no disabilities or damage, and have reached sexual maturity should be selected for breeding.

2. Breeding of breeding frogs: The frogs selected for breeding should be fed intensively before hibernation to make them fat and strong. They should be kept fed when the temperature reaches above 12℃ in winter to reduce the energy consumption in the body in winter and maintain the growth of the stone frogs and the good development of their gonads.

3. Breeding and spawning: Stone frogs usually breed in April with a male-female ratio of 1:1. The stocking density of the breeding frog pond is 15-20 per square meter. Breeding frogs usually pair up after 9 pm, and the breeding female frogs ovulate at 4-7 am, usually laying 300-500 eggs each time. The eggs should not be stirred within 1 hour as much as possible to prevent the eggs from breaking and reducing the hatching rate. Avoid interference when the breeding frogs are breeding and laying eggs.

4. Artificial incubation: The fertilized eggs of stone frogs are very sensitive to external changes from the beginning of their development to the stage of tadpole hatching. The entire incubation process should meet technical requirements such as appropriate temperature, pollution-free water, disinfection of frog eggs, and oxygenation of the incubation pool.

5. Tadpole breeding: Under artificial breeding conditions, after the mother stone frog lays eggs, the eggs can hatch into tadpoles after 10 to 15 days of artificial incubation. After hatching, the tadpoles usually attach to the bottom of the pond and the egg membrane, rarely move, and do not forage. After three days, the activity level increases and they begin to forage.
