The ditch-growing frog, also known as a semi-manual frog, is a species that can be collected and raised from pupae to adult frogs. Farmers can assist in the process by using artificial methods to increase the survival rate of the young frogs. Once they are released into the forest, they grow naturally by foraging on their own. This article focuses on seven key areas that farmers should pay attention to when raising these frogs, helping them avoid common mistakes, improve the survival rate of the young frogs, and ultimately achieve better economic returns.
1. Ensure sufficient water in the hatching pool
During dry seasons, water supply can be unreliable. To prevent the pond from drying out, dig a deep pit in the center of the hatching area, creating a funnel-like shape. This allows the young frogs to hide in the deeper water when the surface level drops. Check the hatching pool daily and refill it as needed to maintain a stable environment.
2. Monitor stocking density carefully
In the early stages, the number of frogs per square meter should not exceed 4,000. Overcrowding can lead to stress and disease. If the density becomes too high, consider transferring some frogs to other pools. As the frogs grow older, reduce the number of individuals per unit area gradually.
3. Protect against natural predators
Before entering the forest, young frogs are vulnerable to birds, snakes, and rats. Ducks are another threat. It's important to secure the hatching pools, block any entry points for snakes or rats, and take measures to control these predators. Regular inspections and protective barriers are essential.
4. Prevent red leg disease
Red leg disease is a common illness among forest frogs. If detected, isolate the affected frogs and place them in a solution of 5% potassium permanganate for 24 hours. Afterward, return them to a clean, normal pond to continue their development.
5. Choose a safe path uphill
When moving the young frogs to higher ground, avoid steep slopes or cliffs. Instead, guide them along gentle paths. A rough or uneven route can attract predators and make it difficult for the frogs to find food, leading to high mortality rates.
6. Provide supplemental feeding
If the initial population is too dense, the natural insects in the forest may not be enough to sustain all the frogs. In such cases, you can introduce low-grade yellow mealworms to supplement their diet and ensure adequate nutrition.
7. Prevent human and animal disturbance
When moving the frogs uphill, avoid areas where people collect vegetables or graze livestock. These activities can trample the frogs and cause unnecessary harm. Implementing controlled access and clear guidelines will help protect the young frogs during their transition.
By following these practices, farmers can significantly improve the success of their frog farming operations and enjoy greater profitability while maintaining a sustainable and healthy environment for the frogs.
