Due to unsatisfactory temperature and humidity conditions, snail eggs may fail to hatch, or the snails may not be removed from the soil in time. This can lead to an extended incubation period—often longer than the typical 15 days. When this happens, the eggs may not have fully matured, which significantly reduces the hatching rate. To improve this, two effective methods—cover soil incubation and cloth incubation—can be used to enhance the success of snail egg hatching.
1. **Cover Soil Incubation**
Begin by filling a wooden box with about 10 centimeters of fine sand. Maintain the moisture level between 30% and 40%. Spread the snail eggs evenly across the sand surface, then cover them with a thin layer of 1.5 cm of additional sand. Keep the sand consistently moist throughout the process. Under ideal conditions where the soil temperature ranges from 20°C to 30°C, the eggs typically hatch within 7 to 15 days, resulting in small, healthy snail hatchlings.
2. **Cloth Incubation Method**
In this method, place the snail eggs on a layer of sand inside a wooden box. Then, cover the eggs with 2 to 3 layers of damp cloth to maintain high humidity. Ensure the environment stays at a temperature between 20°C and 30°C, with relative humidity above 80%. With these conditions, the eggs usually hatch within 12 to 20 days. This method is especially useful when maintaining consistent moisture levels is challenging, as the cloth helps retain humidity effectively.
Both techniques are widely used in snail farming to optimize hatching rates and ensure a higher survival rate for young snails. By carefully controlling environmental factors such as temperature, humidity, and moisture, breeders can significantly improve the overall success of their snail egg incubation process.
