Five Technical measures for Disease and Pest Control of cultured Green Shrimp in Summer

The disease of green shrimp is more frequent in summer. In order to reduce the risk of culture, the following work should be done:

1. Disinfect the shrimp pond water body. First, the whole pool of dibromohydantoin 0.25ppm was sprinkled for sterilization, and then spilled again at an interval of half a month until early July. It was continuously used for more than 3 times, and it can also be used alternately with other drugs.

two。 Drug prophylaxis. Mix the medicine with the mixture and feed it. With florfenicol powder aqueous solution concentration of 3%, every 50 kg of feed mixed with solvent 15 murine 18 jin, feeding, this can effectively prevent shrimp disease from the mouth, 5 Mel 7 days as a course of treatment, continuous use of 2 Mel 3 courses of treatment. 3. Prevention and treatment of shrimp disease: for bacterial diseases such as red leg, rotten Gill and enteritis, garlicin (0.2%), florfenicol (0.2%) and immune polysaccharide (0.5%) can be added to 50kg feed for 7 days. Combined with 0.3ppm povidone iodine whole pool sprinkling disinfection, 3 days later, the concentration of 1ppmEM original dew or Bacillus subtilis to improve the water quality, the general condition can be controlled. 4. Put in organic fertilizer in time to cultivate motorized plants in the water. As drugs are often used in shrimp ponds, a large amount of organic matter in the water is consumed, which is not conducive to the normal growth of shrimp, so it is necessary to put in organic fertilizer. The fermented chicken manure was evenly applied around the pond, and immediately after application, the aerator was activated to increase the oxygen content in the water to prevent the floating head of the shrimp. 5. Do a good job of inspection in time, find signs, and immediately take effective measures to put an end to accidents. For example, before a thunderstorm, vitamins are put in half or stopped to prevent flooding; disinfectants are not used during thunderstorms; and more aerators are turned on after thunderstorms to maintain the ecological balance of the water body. Topdressing in time, when the weather is fine, dry sprinkle with the king of new living bacteria mixed with zeolite powder to replenish the beneficial bacteria in the pond bottom and water body in time to inhibit the growth of harmful bacteria.
