Species retention and incubation management of earthworms

**I. Breeding of Earthworms** **Principle:** Maintaining a clean and healthy environment is essential for successful earthworm breeding. **Egg Mass Propagation Method:** This method is widely used due to its efficiency. The eggs are small, light, and have a high colonization rate, making them easy to transport and manage. There are also methods involving the introduction of larvae or adult worms. However, in most cases, egg introduction is preferred. When selecting eggs, it's important to ensure they are strong and not damaged. Eggs that are too soft, overly large, or unevenly laid should be discarded. To maintain quality, the second and third batches of eggs are typically selected. These eggs are uniform in size and develop more consistently, which helps avoid delays in hatching and ensures uniform larval growth. The environment for breeding adults should be well-organized, with an ample supply of protein-rich feed. Overcrowding should be avoided—ideally, 5–7 kg of worms per square meter is recommended, with about 0.15–0.25 kg of live eggs per square meter. Too many adults can lead to overcrowding, resulting in slow growth, weakness, and even death. **II. Egg Incubation** Managing the hatching process is one of the most critical stages in earthworm farming, as it directly affects the success and economic returns of the operation. **Principle:** The key factors during incubation are insulation, moisture, and good air circulation. There are several incubation techniques available, such as indoor temperature-controlled incubation, constant temperature incubators, and kerosene lamp heating. In my experience, the latter two are more suitable for small-scale breeders, while indoor temperature control offers more precise and consistent results. Incubation should never take place outdoors. A room with controlled ventilation and stable temperature is ideal. If the temperature fluctuates too much, the eggs may stop developing and take 5–7 days to return to normal. This is especially important during winter. For optimal conditions, place 4–5 kg of eggs in a 50 cm diameter plastic basin with smooth inner walls. Mix two-thirds of the eggs with a moist soil medium, keeping the soil humidity around 35–40% (when squeezed, it should form a clump but not drip). The soil layer should be about 8–10 cm thick. Prepare the soil in advance, and ensure the temperature difference in the incubation room does not exceed 5°C. Under proper temperature and humidity conditions, the eggs develop over time. During this period, the eggs absorb moisture from the soil. After 3–5 days, the soil begins to dry. At this point, avoid spraying water directly on the eggs, as this can cause compaction and block air flow, leading to suffocation of the larvae. Instead, replace the dry soil with preheated, moist soil. During soil changes, some larvae will emerge and can be transferred to breeding pits. Maintain a consistent temperature between 25–30°C (preferably 28°C) throughout the incubation period. Gently turn the eggs once or twice daily to improve air circulation and prevent stagnation. Be careful not to touch or damage the eggs while turning. After approximately 30 days, some larvae will begin to hatch. At this stage, you may notice some locusts on the surface of the soil—these are often parasitic on damaged egg masses. Don’t panic; use a sieve to remove them. By day 40–43, a large number of larvae will appear, and you’ll see thousands emerging. Sieve the larvae every other day and distribute them appropriately. When sifting, handle the larvae gently to avoid injuring them. They are milky white and resemble sesame seeds, hence the name "sesame bugs." As the hatching continues, some empty shells will remain. When these shells make noise during screening, use a pestle to carefully remove them. Pay attention to temperature differences when removing shells. In the later stages of hatching, some locusts may still appear, which is normal. They can be removed through sieving. After 50–60 days, most of the larvae will have emerged. Some egg masses may die off, but this is natural and expected. Not all eggs will hatch, so a 100% hatching rate is not guaranteed.
