| The basic breeding environment and equipment for South American Shrimp |
1, pool (sedimentation tanks)
Reservoir is exports Penaeus vannamei culture key facilities is an important guarantee for high and stable yield. The establishment of the reservoir is designed to handle precipitation purification of water for aquaculture, usually the total reservoir capacity of the water bodies breeding 20% to 35%, not less than two, and this may rotate, effective control of harmful substances (pathogens , viruses, pollutants) into shrimp ponds. MacRitchie there should be a channel or channel and the pond connected to the pond with water pumps, water pumps and channels should shrimp ponds or pipeline capacity and accessories, if water recycling, we must increase the number of specific purification facilities, after purification treatment after before they can enter the reservoir. Water to meet national green aquatic breeding water required standards.
2, sewage treatment pond
Sewage treatment pond aquaculture is the discharges in the decontamination dedicated pool of water to meet emissions standards to prevent the pollution of the surrounding water for shrimp aquaculture industry to create conditions for sustainable development.
3, drainage channels (channels)
Into the drainage channels should be independent of the design, the intake and outlet should try to stay away from. New shrimp ponds outfall shall not be located in the shrimp market has been built or Jan water intake station near the channels should be in accordance with section hydrodynamic principles to the design, to avoid excessive flow-loss channels, or water overload and overflow pipes outside. Drainage channels * Change in addition to the normal needs, we must also consider the storm drainage and shrimp to the rapid drainage needs. Good drainage channels into shrimp ponds can easily manage and reduce the occurrence of disease.
4, pond
Area of 2 to 10 acres suitable for some larger shrimp market, and the layout of its various ponds along the inlet channel in a "non-" shaped array. Rectangular, east-west, aspect ratio 3:2 ~ 1, preferably at the end of hard mud, sand or better is rock, mud is not more than 10 cm, depth of 2 m design, the water level in the day-to-day 1.2 to 1.5 meters, installed in the pond into the opposite row channels, Jin, Pai separate outfall lower intake higher. Jin and exclusive channels into displacement, in the request within four hours can be hired, the entire row of the pool water more than one-third.
5, the necessary equipment shrimp market
Shrimp market should have its water to the auxiliary equipment, aerobics equipment and analytical instruments. Water aerobics machine optional car-aerobics machines, impeller aerobics machines and aerobics-jet machine, usually 1-2 per kilowatt load acre pond configuration, if high-density culture of pool, with a corresponding increase in the allocation, by Oxygen machines should be installed correctly use, pay attention to electricity safety, we must also have an alternate aerobics machines and standby generators to prepare for emergency, in the absence of electricity will be able to use diesel-driven aerobics equipment.
With a certain amount of shrimp to market shrimp on the water environment and for monitoring health status, environmental factors should be established Detection of room, the equipment must be configured: biomicroscopy, salinity of (proportion), the water temperature of, dissolved oxygen analyzer , and the pH of transparency set. Conditional shrimp market also set ammonia, total alkalinity detection apparatus, microbial cultivation equipment, the dye liquor and pathogen detection kit. |
