This method can use empty rooms or sub-areas of housing, such as balconies, corridors, aisles, basements, cellars, or the construction of semi-subterranean farming sheds as breeding sites. Set the breeding box and keep the snail inside the box. One of the most common farming methods when breeding snails with a terrarium.
The terrarium can be made of scrap wood, used packing boxes, non-toxic plastic plates, bamboo, wicker, etc., but it must not contain materials containing aromatic substances, tannins, and resin liquids, as well as abnormal odors. It must not be used as lead paint or bitumen. , pesticides, fertilizers, radioactive materials and other materials. The size and material of the breeding box can be determined according to the feeding conditions. General breeding box specifications: available 1.0 - 1.5 cm thick wood, do grow 60 cm, 40 cm wide, 35 cm high or 75 cm long, 45 cm wide, 35 cm high wooden box. Ready-made wooden boxes of different specifications can also be used, but the height of the wooden box is preferably not more than 35 cm. When an overly high snail falls from the top of the box or the wall of the box, it is easy to break the screw shell, and light affects the growth. death. The cover can be covered with plastic or wire screens, which can prevent snails from fleeing and make it easy to observe. It is advisable to keep the area of ​​the bottom of the rearing box no more than 1 square meter for easy movement and management. When the breeding specifications are large, the breeding boxes can be placed on shelves so that the space can be fully utilized to form a three-dimensional rearing.
The diameter of the cover net of the snail cultivating box is generally 10-15 mm, which can prevent 50-70 snails to lay eggs. The hole size of the screw cap cover is 8 - 10 mm, which can be placed into 100 - 150 screws. The screw hole diameter of the box is 2 - 3 mm, and 500 young snails can be placed. The size of the larvae of the breeding cage depends on the size of the snail eggs and should be based on the principle that the granules are not leaked.
There may be a few gaps in the wall of the breeding box or a moving screen door for observation, feeding and cleaning. The bottom of the box can be covered with a layer of small gravel or small pebbles to facilitate draining. A layer of 8-10 cm humus and sand mixed with sandy loam is laid on the bottom of the box, and some earthworms can also be fed and mixed. Farmers in some places have achieved certain results by adopting foaming plastics on the bottom of the box. The advantage is that it is easy to clean the excrement and food residues, but it has some obstacles and impacts on snails spawning, and the cost is higher, most of them are not used. .
In order to make full use of the site, the terrarium can be placed on top of one another for three-dimensional breeding. In the three-dimensional breeding, the level of the overlapping breeding boxes is height in order to operate. If large-scale indoor breeding, can be designed as a 50 - 300 square wood production unit, both sides of the angle or other materials to build a shelf. The bottom of the shelf is a concrete slab or turntable. Drainage ditch can be set up on the platform. The middle of the two shelves is the sidewalk, which is convenient for operation and management. Each shelf is 30-35 cm wide and 40 cm wide. The trough of each terrarium just protrudes 10 cm from the shelf. The shelves can be divided into 5 layers and 200 breeding boxes can be placed on each floor.
In indoor breeding, its breeding facilities and conditions are also varied, and farmers can use their conditions to adapt to local conditions.
