The key to improve the survival rate of frogs in the United States

To ensure the health and survival of American frogs, effective management during the flood season is essential. This includes improving breeding practices and enhancing the survival rate of young frogs. Here’s a comprehensive guide to achieving this: 1. **Breeding Management**: Each pair of frogs should be provided with at least 2 square meters of space in the breeding pond. Aquatic plants should be planted to help frog eggs adhere properly. One month before spawning, it's recommended to feed them live fish to meet their nutritional needs. Regular water changes are crucial to maintain clean and healthy conditions. Once the frogs have laid their eggs, they should be removed promptly to prevent the adults from eating the eggs. 2. **Egg Incubation**: Frog eggs should be placed in 40-mesh nylon gauze cages for hatching. Approximately 10,000 eggs can be placed per cubic meter. These cages can be set up either in ponds or dedicated frog pools. They should be covered with shade nets to protect against direct sunlight and heavy rain. 3. **Feeding Young Frogs**: After hatching, which usually occurs within 3–4 days, young frogs should be fed finely crushed egg yolk for two consecutive days. Soymilk should be given twice daily. After about 12–13 days, the tadpoles are typically moved to sterilized earthen ponds for further development. 4. **Stocking Density**: The stocking density should be carefully managed. In spring, lower densities are preferred, while slightly higher densities can be used in autumn. A general guideline is to allocate 60–80 square meters per 10,000 frogs. Any leftover frogs should be transferred to another pool to avoid overfeeding and waste. 5. **Feeding Practices**: High-quality commercial feeds designed specifically for frogs are commonly used. If using homemade feed, a submerged food table should be installed about 25 days after moving to the earthen pond. The table can be made from old snake skin bags with a 6 cm border. One feeding station is needed per 10,000 frogs, placed 30 cm below the water surface for easy monitoring and to reduce feed wastage and water pollution. The tables should also be regularly disinfected. 6. **Water Quality Control**: Maintaining good water quality is vital. The water should be oily green with a transparency of around 25 cm. Cultivating plankton helps provide natural food for the frogs. It’s important to avoid both overly rich and too clear water. Fresh water should be changed regularly. Planting crops around the pond helps prevent muddy runoff after rain, which could cloud the water and harm the frogs. Submerged plants also help regulate water temperature and provide shelter for aquatic organisms. 7. **Disease Prevention**: Common diseases include bacterial enteritis, red leg disease, tail rot, and air bubble disease. Prevention involves maintaining clean water, proper feeding, and regular disinfection. Water treatment can include products like chlorine dioxide or lime sulfur, while internal medications such as Frog Disease Ning or Yujiale can be mixed into the feed. A typical treatment course lasts three days, ensuring early intervention and prevention of outbreaks. By following these detailed steps, frog breeders can significantly improve the health and survival rates of their American frogs throughout the breeding cycle.
