Two ways of aquaculture

1. Overlay box. Use a steel frame or concrete bench as a support and place an active colonization box on it. Box can be made of wood, bamboo, willow and other materials, it can also be plastic. Specifications are 80 centimeters long, 50 centimeters wide, and 20 centimeters high. They can hold 50 kilograms of material and they can be lifted. It is also possible to overlap the boxes in the form of a product without brackets. The box and the box are separated by wooden strips to facilitate ventilation. In the box, fully feed fermented and decomposed feed was put into the tank, and 10,000 puppies with similar hatching dates were put into the box of each square meter. Can be farmed for 40-50 days. The time for picking out fleas depends on the condition of feed intake, the size of the individual, and the population density. During the breeding period, no more feeds and grazing will be conducted, nor will the dung be taken. In addition to the thermal insulation of the sprinkler and the inspection of the natural enemies, no other work is required. When harvesting, dump the box one at a time, separate the carcass and manure, and then re-feed and plant the fish. Since there is no basis for feed and feed, the requirements for feed processing are strict, and the ratio of feed and feed and the time consumed are calculated. The collection time should be set in the period when most of the annulus is prominent and the individual begins to spawn. Breeding earthworms in this way can be used both indoors and outdoors, as well as bedsteads and bedsteads, which are easy to integrate with the “three groups of public breeding”, facilitate the relocation of colonial breeding sites, increase labor efficiency, and increase facilities. The utilization rate, suitable for enterprise production and mechanized operations, is a breeding method worthy of promotion. 2. Louver box type. Blind box-type breeding method, the principle is consistent with the overlapping box. Blind box structure is reinforced concrete, each box is diagonally connected, and the distance between each layer is preferably 20 centimeters. It is shaped like a shutter box used by meteorological station. Oblique boxes are divided into two symmetrical columns with a storage room in the middle. When breeding, the material will be put into the storage room first, and then the material will be allocated to each oblique louver surface from the top to the bottom to form a slant culture bed. If electric vehicles are used for feeding, the material can be directly unloaded at all levels of inclined louvers to reduce one process. After watering, put a corresponding number of small cockroaches on each slant culture bed, and wait until the feed is basically decomposed and the young cockroach is mature. Its feeding, sprinkling, watering, and collection can all be mechanized or semi-mechanically operated. It is suitable for large-scale production in an enterprise, and it is also an appropriate method for raising quails in winter greenhouses.
