Intimate choice Usually when you choose to have a strong, strong ability to close the shell, complete shell, bright color as the standard. The best age is 4-6 years old. The newly hatched quail has few eggs and the hatching rate is low; over 6 years old quail, the amount of spawning is small and the maturation is not the same. Static water harvesting method Put the kakao 蚌 mother rake for half an hour or put it in the sun for 10-20 minutes and put it in a tub with a diameter of about 50 cm. Add water to immerse the corpse, then you can see the mother larvae to expel the larvae and immediately transfer the mother lice to another pot. In the water, put the host fish and stir the pot water to increase the chance of dissolved oxygen and contact between the fish and the larvae and increase the seedling collection rate. Each pot can be filled with 3-4 female locusts, 100-200 larvae with a body length of 10 cm, or about 30 croakers. After 10 to 20 minutes, it is estimated that there are about 200 larvae attached to the larvae, fins, scales, etc. of each fish, that is, the fish are moved to the cultivation pond for raising. Then put the second batch of host fish seedlings until the mother quail empty. Water picking method Put the female quail in a water culture pond, put 3-5 pieces of water per square meter, about 200 tails of host fish. The flow rate of the introduced water should not be too large to prevent the larvae from escaping with water, and the seedlings can be harvested within 2-3 days. Net cage method A small (21.3l meters) cage was set up on a wide water surface with good water quality. The mesh was made of polyethylene and 30 mesh mesh. The cage is suspended on the fixed frame, and 10-20 females are placed in the cage, 300-500 tails of the host fish are collected, and natural seedlings can be harvested for 2-3 hours. Feeding of host fish The host fish should be carefully reared and managed. The amount of water per cubic meter of water should not exceed 200, and the water depth should be maintained at about 0.5 meters. Requires smooth water flow, fresh water, and adequate oxygen. The feed was fed twice a day, and the water temperature was measured three times daily, that is, once every 8 o'clock, 12 o'clock, and 17 o'clock. The average value was calculated and recorded. When accumulating to 180°C, prepare the seedlings in a timely manner. For example, clean up the bottom of the nursery pool, spread 2 cm thick sand, and then drain to 15 cm depth. When the white spots on the host fish have broken membranes, they should be immediately picked up and placed in nursery ponds to allow the seedlings to gradually fall off and sneak into the fine sand, and to control the water flow to prevent the seedlings from being washed away. When the water temperature increases to more than 200°C, it indicates that the seedlings have fallen off and the host fish should be picked up to avoid swallowing the seedlings.
