First, it's important to focus on self-producing and self-inflicted childishness. Once the larvae hatch, they go through a short incubation period before being introduced into the greenhouse. During this time, they quickly adapt and enter a normal growth phase. Juveniles that start feeding early grow rapidly and have a high survival rate, making this stage critical for successful breeding.
Second, proper disinfection methods are essential. Before entering the pool, the juveniles must be sterilized. Common methods include using 5% saline or a 5ppm malachite green solution, with a dip lasting around 10 minutes. However, it's important to avoid using potassium permanganate, as it can be too harsh and may burn the turtles if the concentration is slightly higher than recommended.
Third, stocking specifications and density should be carefully managed. The larvae entering the pond should weigh more than 10 grams each. These individuals tend to grow quickly and are more resistant to diseases. The ideal stocking density is 18-20 per square meter. Overcrowding can lead to aggression and lower survival rates. When stocking, it's important to separate strong and weak individuals and ensure uniform size within the same pool.
Fourth, the water depth in the greenhouse should not be too deep. A depth of 30-40 cm is optimal. If the water is too deep, the soft-shelled turtles have to swim from the bottom to the surface to eat and breathe, which increases their energy expenditure and negatively affects their growth.
Fifth, it's beneficial to manage water hyacinth in the greenhouse. Removing some of the water hyacinth can expand the turtles' habitat and reduce external disturbances. Additionally, water hyacinth helps purify the water, has strong root systems, and regenerates quickly. It's also a preferred plant-based food for the turtles. A coverage rate of 30-40% is generally recommended.
Sixth, using photosynthetic bacteria can help regulate water quality. In a non-flowing environment, the turtles are usually fed high-protein feeds, leading to leftover food and waste that can degrade water quality. Frequent water changes or increasing water levels can stress the turtles and hinder their growth. Photosynthetic bacteria can improve water conditions, promote the growth of natural food organisms, and reduce pollution.
Seventh, increasing the number of feedings can enhance food intake and efficiency. By feeding more frequently but in smaller portions, the turtles remain in a semi-starved state, encouraging them to eat more and utilize nutrients better. Feeding 4-6 times a day is typically effective.
Lastly, maintaining a quiet environment is crucial. Soft-shelled turtles are sensitive and easily startled. Daily management and feeding should follow a fixed schedule, with quick movements and short durations to avoid disturbing them. It's important to prevent unnecessary people from entering the greenhouse during feeding periods and to avoid moving the turtles at all during this time.
