White jade snail breeding experience
In the white jade snail industry, I have accumulated practical experience from 1994 onwards. In the face of the current widespread recognition of white jade snails and the related misunderstandings, I would like to stand up and say a few words, hoping to cause Dear friends, I'll give you tolerance when I'm wrong. I want to talk about some of my personal ideas from the following aspects. I hope I can play some role. First, on the temperature white jade snail is a cold-blooded low animal, it does not have its own function to adjust the temperature, so! In the whole process of breeding white jade snails, giving the temperature suitable for its growth becomes the key to the success or failure of white jade snail breeding. The optimum growth temperature of white jade snails is 22 to 30 degrees, and the clams gradually stop eating within 18 degrees, 15 degrees. Some snails inside will enter semi-hibernation and may cause freezing damage. A small number of open-air snails above 35 degrees in the summer will be in a state of hibernation. At this time, they should be sprinkled with water to increase the humidity and reduce the temperature. Therefore, shading should be applied where possible. The net will block the sun and avoid exposure. It must not be exposed directly under the sun. Otherwise, it will easily cause the snail to shrink due to high temperature exposure. Commonly used heat preservation methods are as follows: (1) Earth dragon heat preservation method: A 25-cm square hole is drilled at the base of the wall, and a firewood stove is built. Then two bricks are arranged at a height of 30 cm and a width of 24 cm. The two brick ground dragons, which are the same horizontal as the rearing room, are concealed below the ground where the breeding frame is placed. At the other end of the wall, the two ground dragons meet to form an exit. The exhaust gas is discharged from the smokestack. As long as the firewood does not go out during the day and night, the room temperature can be maintained between 25-30 degrees. In the vicinity of the stove's faucet, more water should be sprayed to regulate the indoor air temperature and humidity, and to reduce the high temperature at the ground. (2) Plastic greenhouse insulation method: The scale of this method can be large or small, (you can also use idle or low-cost vegetable greenhouses), in the leeward sunny place, use double transparent plastic film to build greenhouses, use the ground temperature and the sun Irradiation assisted insulation, this method is suitable for the south, in the winter when using greenhouse insulation three-dimensional breeding of snails also need auxiliary heating, heating methods are flexible, with fixed, mobile two simple insulation facilities can be. (3) Insulation method for tunnels: On the eve of wintering, the snails will be transferred to the basement, air-raid shelters, caves, and other civil air defense aquaculture can effectively save energy, and they can also choose outdoor leeward locations or use terrain and solar energy to reconstruct the tunnels. Insulation room, this use of ground temperature method also requires other insulation methods. (4) Wood chip and coal stove insulation method: The two kinds of fuel furnace exhaust pipes are made of tin sheet, the pipe diameter is 20-25 cm, and the end of the three-core coal stove exhaust pipe is 6-7 cm. The end of the exhaust pipe is 2.5 centimeters. The exhaust pipe bends with the indoor passage and extends out of the room to exhaust the exhaust gas to facilitate the accumulation of heat and purify the indoor air. (5), heating insulation method: This method uses the heating pipe, boiler exhaust or some factories to discharge cooling water into the breeding room as a heat source, for snails winter, if stopping the water should immediately use other methods to warm. (6) Power insulation method: The main use of light bulbs and electrical equipment, light bulbs can be placed between the box and the box, 30 cm from the ground, the lamp power is not more than 100W is appropriate, you can install a few more, in order to balance Insulation. (Note! The cost of electrical insulation is too high. Once the power is cut off at night, it will cause losses.) Insulation room general indoor area to 20 square meters of single room is good, in the room to do a variety of three-dimensional box-type containers or wooden boxes, box padding 4-5 cm sand or vegetable garden soil for snails habitat, generally a 20 The square-meter house can be finished with about 10,000 white jade snails over the winter, and the entire heat preservation cycle is suitable from mid-November to mid-April of next year, which takes 5 months. Note: The exhaust gas generated from the heat source and the thermal insulation equipment is toxic, and must be observed during the winter insulation period. Second, on the humidity White jade snail is a "terrestrial shellfish" animal, although not like snails living in water, but it also requires a high environmental humidity and soil moisture, in the entire farming process, spray water for two to three times a day ( Fog), and keep the mother screw box ventilation, the soil should be kept moist, the general standard is "pinch into a group, sprinkled into the sand", especially during the high temperature during the summer, we must pay attention to the timely spraying of water, humidity is not easy to cause summer sleep is still Shrink the shell and stop growing. White jade snails are very sensitive to humidity, so! It is very important to have a good grasp of the humidity. In short! Cultured white jade snails should follow the "three high" culture mode (high temperature, high humidity, high calcium). Third, on food white jade snails like to eat green plants and leaves of juicy green leaves, fruits, Tengben and other plant leaves (plus a small amount of concentrate feed; chicken, pig feed, rice, bean cake, rice bran, etc.), And spray the feed water wet. With the continuous growth of white jade snails, but also need to add the appropriate amount of calcium to be added, but the white jade snail sensitive to alkali, calcium should pay attention to the use of calcium foods. In the concentrate feed, appropriate amounts of bone powder and other ingredients can be added. At the same time, old hydrated lime can be added to the soil in the cultured soil to make it possible to supplement a large amount of calcium, especially a kind of snail, which is particularly important. When the winter heat preservation is proper, the food intake of the snail does not decrease, and the quality of the food is properly increased so that it can grow normally during the incubation period. At the same time, it is necessary not only to take care of the partial eclipse of snails, but also to take care of the omnivorous nature of snails. Therefore, do not feed a single feed for a long period of time and exchange a green feed for snails to eat at intervals. Do a variety of feed mix preparation. Persist in removing residual feces every other day and clean the floor. (Depending on the situation, the food can be fed once every other day. Each 100 species of snails is fed with about one or two concentrated feeds each time). 4. How to incubate mother ovipositor After spawning, use a spoon to collect the eggs in time and place them in the incubator. Place 1 centimeter of feeding soil on the bottom of the box, then put the snail eggs, and try to keep the eggs as they are. Cover the eggs one centimeter or so. The grazing soil was sprayed twice a day (fog) twice, and it was hatched at about 25 degrees Celsius for about 12 days. Then the young snails were put into the terrarium, and the leaves were sprayed and sprayed for 20 days. Or slightly larger can be put into the wild or enter the terrarium for normal feeding, and after about one month, feed a small amount of concentrate feed. V. Viral infections and prevention Some current breeders have listened to biased beliefs, and they have been thinking of overnight riches. They are unrealistically introduced in large quantities at one time. Because breeding techniques have not been able to hold on well, and because of brain heating, In the future management, due to the emergence of such problems and the confidence to fall quickly with the decline of heat, similar failed households have become commonplace, due to the prevalence of several runs before the decision to engage in white jade snail cultivation. The company visited and looked around, looking for farmers to understand the situation, carrying out aquaculture technology demonstration and comparison of seed prices, and even bringing back a few samples each time to persuade family members to support him to develop aquaculture, etc. It is easy to cause cross-infection with viruses. He never expected that he had already laid a root cause in his own snail business. Once introduced and fed, if it was indoors, both the environment and technology were at a disadvantage for snails. Not one month will lead to a large-scale virus outbreak, because it is a late virus infection, so the post-natal hatching rate is still normal But the survival rate was very low, as in this case for now is no good drugs to cure, stocking field to be appropriate only when the temperature to be natural recovery self nursed back to health, so! It is strongly recommended that farmers and breeding units pay a high degree of attention to this issue, that is, they must conduct long inspections and avoid touching, let alone return a few families to “look at their wives†and they would like to see the support of the other half of the forces. The species-providing unit should also remind the investigators to eradicate the occurrence of such situations from the source, and must not be buried quietly. The special breeders pay attention to the word “specialâ€, and the planned immunization and epidemic prevention are necessary. Indispensable, in addition to this, it is necessary to introduce the “kind of eagerness†psychology that abandons the fast-growing wealth, to be realistic, and to develop steadily, to purchase a small amount of snails first, and to wait for the door to roll and develop. Speed ​​is not up to this principle. In addition! When the young snails are sized like beans, you don't have to feed the concentrate! The garden of your snail will be fat, and the individuals are not ideal. The premature sexual maturity leads to deterioration of quality. The above is my personal point of view of the experience. I would like to use the Internet for reference by my friends.
