The crickets are also called crickets. On the sides of their heads, there is a posterior gland behind the ear, which contains a white serum. It is called a "crisp cake" in medicine and is a valuable medicinal material. With the increase of aquaculture, the author systematically summarizes the technology.
First, build the pool
Choose a place where the water source is sufficient and drainage and irrigation are convenient. Large-scale breeding should build spawning ponds, ponds, and ponds. General farmers can make modifications based on the existing water surface. There is less sewerage, and generally about 40 broilers per square metre of water can be cultivated. Chengchi Lake area is generally 1 mu ~ 2 acres, Dianchi 10 square meters ~ 40 square meters, spawning pool 10 square meters. Chengyu Pond should maintain a ratio of 1:1 between the gap and the surface of the water, keep the depth of the pool at 80 cm, and build a wall with a height of 80 cm or more around the pool and wipe it to a smooth surface. Or use other materials made of anti-escape facilities. Put a awning above the pond or plant vines such as gourd, chayote and grape. There are a number of caves of varying sizes in the walls of the wall, and some plants such as corn, soybeans, and damp-tolerant plants are planted in the gaps. Some aquatic plants are placed in the pool.
Second, seed breeding
From late March to late April each year, there are three ways to solve the problem of seed production: first, after the rain in the spawning season, look for quail eggs in the still water, and fish the eggs back into the pool or directly place them in the pool. In the culture pond, put 2500 eggs per square meter, the temperature is 18 °C ~ 25 °C, 3 days can be hatched. To use this method must be enough at a time, otherwise the hatching time is inconsistent, and the size varies, affecting the survival rate. Second, when the temperature is stable above 10°C after the convulsions, catch the overwintering cockroach at the wet places in the wild. Select individual individuals and put them in the spawning pool in a ratio of 3:1. Let them be naturally mated, spawn, fertilized, The fertilization rate can reach more than 90%. Eggs produced each day should be collected in another pool for natural hatching. Otters that produce eggs need to store in another pool, and no production will continue to be retained.
Third, nursery seedlings
The newly hatched quail, often sucked on egg shells or aquatic plants, does not feed on its own yolk sac. After 2 days to 3 days, Xiao Lan began to eat algae or other bait in the water. In the breeding ponds, a small amount of fermented pigs, cow dung, and plankton should be introduced one week in advance. Do not spill the excrement after entering the pool to avoid injury. Spawning pools, Dianchi water depth generally maintain 20 cm to 40 cm. Can be fed chopped vegetables, fish intestines, pig blood, Taomi Shui, once or twice a day. After half a month of cultivation, when the body is up to 3 centimeters in length, it can be removed and put into a larval pool for culture. It takes about 40 days to hatch the eggs from the eggs to the larvae.
