Due to improper temperature and humidity conditions, snail eggs may fail to hatch, or the snails might not be removed from the soil in time. This can lead to an incubation period that exceeds the normal range—usually around 15 days. In such cases, the eggs may not have fully matured, which significantly lowers 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**
Start by placing a layer of sand about 10 centimeters deep in a wooden box. The sand should maintain a 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 sand. It’s important to keep the sand consistently moist throughout the process. Under ideal conditions where the soil temperature ranges between 20°C and 30°C, the eggs typically hatch within 7 to 15 days, resulting in small, healthy young snails.
2. **Cloth Incubation Method**
In this method, place the snail eggs on top of sand inside a wooden box. Then, cover the eggs with 2 to 3 layers of wet cloth. The environment should maintain a temperature between 20°C and 30°C, with a relative humidity of at least 80%. This setup helps create a more stable and humid microclimate for the eggs. With these conditions, hatching usually occurs within 12 to 20 days, allowing for better control over the development process.
Both techniques are widely used by breeders and researchers to optimize hatching rates. Choosing the right method depends on the specific species of snail and the available resources. By maintaining proper environmental conditions, you can greatly increase the chances of successful hatching and ensure healthier, more vigorous snail offspring.

Disposable surgical instruments are single-use medical devices that are used during surgery and discarded after use. Some examples of disposable surgical instruments include:
1. Scalpel 2. Tweezers 3. Scissors 4. Needle 5. Suture material 6. Surgical drapes 7. Surgical masks 8. Surgical gloves 9. Ironing pen 10. Trocar and cannula.
Medical tools for surgery:
1. Scalpel: A surgical knife used for making incisions in the patient's skin or tissues.
2. Forceps: A tool used for grasping and holding tissues or organs during surgery.
3. Retractors: Surgical instruments used to hold open incisions or wounds to provide better visibility for the surgeon.
4. Scissors: Used for cutting tissues and sutures during surgery.
5. Hemostats: Used to clamp blood vessels and prevent bleeding during surgery.
6. Suction devices: Used to remove fluids or debris from the surgical site.
7. Needles: Used to suture or stitch wounds.
8. Electrocautery: A tool that uses an electrical current to cut or coagulate tissues during surgery.
9. Endoscopes: Used for minimally invasive surgeries, these instruments allow the surgeon to see inside the body without making large incisions.
10. Laparoscopic instruments: Used for minimally invasive surgeries, these instruments include a camera and specialized tools for performing surgery through small incisions.
