Techniques for Separating Mother Scorpions from Baby Scorpions in Scorpion Farming
1. Separation time: carry out the separation when the baby scorpions have shed their white fibrous embryonic skin and changed from white to orange-red, and their tail segments are turned upward. 2. Separation methods. 1. Picking separation method. After the baby scorpions have climbed off the mother's back, in the evening pick out with chopsticks or tweezers the postpartum mother scorpions that are active outside and have shrunken forebodies, while the remaining baby scorpions stay in the original scorpion pool for rearing. This method is suitable for smaller-scale scorpion farming such as adobe birthing rooms, cement slab birthing rooms and wooden board nest-cell birthing rooms. 2. Glass separation method. First pick out the postpartum mother scorpions with chopsticks and rear them elsewhere, then gently pour the baby scorpions together with the rearing soil from the birthing room onto a glass plate in the middle of another rearing basin, place a wide-mouthed glass bottle under the glass plate, and the baby scorpions will slowly crawl toward the edge of the glass plate and fall into the rearing basin; finally, pour away the rearing soil on the glass plate. This method is suitable for smaller-scale scorpion farming. 3. Separation sieve method. Between pools, build a separation sieve 15-20 cm long, 10-20 cm high and with a pore diameter of 0.3 cm; the separation sieve only allows 2nd-instar scorpions to pass through, while the mother scorpions cannot get through. This method is suitable for large-scale scorpion farming. 4. Automatic separation slide method. Inside the scorpion pool, build a small pool whose bottom is 10-20 cm higher than the large pool, with surrounding edges forming a slope at a 60-degree angle to the floor of the large pool, and lay glass plates on the slope so that scorpions can only slide down and cannot climb up. The four walls of the small pool are glued together from 4 glass plates, and between the four walls and the pool bottom leave a narrow gap 0.3 cm high through which only baby scorpions can pass. During separation, pour the mother and baby scorpions from the birthing room together into the small pool; the baby scorpions pass through the narrow gap and slide down the slope into the large pool, while the mother scorpions remain in the small pool. This method is suitable for larger-scale scorpion farming. 5. Automatic separation box method. Between pools, at a height of 10-15 cm above the ground, build a separation box whose length and width are both 15-20 cm and whose height is 10-20 cm. On the side near the baby scorpion pool, make a slope at a 60-degree angle downward from the bottom plate of the separation box, and between the glass baffle of the separation box and the bottom plate leave a narrow gap 0.3 cm high. During separation, put the mother and baby scorpions together into the separation box; only the baby scorpions can pass through this narrow gap and fall into another rearing pool, and they cannot climb back up, thereby achieving the purpose of automatic separation. This method is suitable for large-scale scorpion farming.
