The key to improve the survival rate of frogs in the United States
To ensure the health and survival of American frogs, it's essential to implement effective flood season management and improve the survival rate of young apes. Here are some key practices to follow:
1. **Breeding Management**: Each pair of frogs should be provided with at least 2 square meters of pond space. Aquatic plants should be planted in the pond to help frogs lay eggs. One month before spawning, feeding live fish can help meet their nutritional needs. Regular water changes are important to maintain clean water conditions. Monitor frog behavior for signs of egg-laying, and remove the eggs promptly after they are laid to prevent the adult frogs from eating them.
2. **Egg Incubation**: Place the frog eggs in 40-mesh nylon cages to protect them during hatching. A density of 10,000 eggs per cubic meter is recommended. These cages can be placed in ponds or dedicated breeding pools, and should be covered with shade nets to protect against direct sunlight and heavy rain.
3. **Feeding Young Frogs**: Begin feeding quail eggs 3–4 days after hatching. Crushed egg yolks can be used as a starter feed, and it should be given continuously for two days. Soymilk should be provided twice daily. After about 12–13 days, the young frogs can be moved to sterilized earthen ponds.
4. **Stocking Density**: Adjust stocking density based on the season. Spring frogs should be kept at lower densities, while autumn frogs can be stocked more densely. Generally, 60–80 square meters per 10,000 frogs is ideal. Monitor the frogs regularly and remove any leftover food to avoid water pollution.
5. **Feeding Practices**: Use specially formulated compound feed designed for frogs. If using homemade feed, install submerged feeding tables 25 days after moving to the earthen pond. The feeding table can be made from old snake skin bags with a 6 cm border. One feeding table per 10,000 frogs is recommended. The table should be submerged about 30 cm below the water surface for easy monitoring and to reduce waste and water contamination.
6. **Water Quality Control**: Maintain good water quality by cultivating plankton for natural food sources. Avoid overfeeding or underfeeding the pond. Regularly replace the water to keep it clear and oily green with a transparency of around 25 cm. Plant crops around the pond to prevent muddy runoff after rain. Submerged aquatic plants can also help regulate water temperature and provide habitat for beneficial organisms.
7. **Disease Prevention**: Common diseases include bacterial enteritis, red leg disease, tail rot, and air bubble disease. Prevent these by maintaining clean water and proper feeding. Combine water disinfection with internal medication. Disinfectants like chlorine dioxide, strong chlorine, or lime sulfur can be used. For internal treatment, use medicines such as Frog Disease Ning or Yujiale, mixed into bait. Treat for three consecutive days as a course to prevent and control disease early.
By following these detailed practices, you can significantly improve the health, growth, and survival rate of your American frogs.
