Technical Field

The utility model relates to a technical field is bred to the water length, specifically is a MBR equipment of suppression aquaculture south america white shrimp vibrio.

Background

In the process of culturing the penaeus vannamei boone, because the water contains a large amount of organic matters and also contains a certain salinity, the culture method is very suitable for the growth of vibrios under the condition, and the existence of a large amount of vibrios can not cause the penaeus vannamei boone to die immediately, but the bodies of the penaeus vannamei boone are not protected by crustaceans when the penaeus vannamei boone is unshelled, and pathogenic vibrios can infect the penaeus vannamei boone when the penaeus vannamei boone is unshelled, so that the penaeus vannamei boone dies.

The existing vibrio inhibiting methods are various, and a chlorine preparation and an iodine preparation are added, and the method comprises the steps of killing the vibrio by adopting nano silver, even antibiotics and the like, but after the vibrio is killed, beneficial bacteria are cultured quickly, a nutrient source in water is consumed, otherwise, the number of the vibrio is increased, the dead body of the killed vibrio also becomes the nutrition of the new vibrio, meanwhile, the rest feed and the prawn feces generated by continuous feeding continuously increase the nutrients in the culture water body, the growth speed of the vibrio becomes the growth speed of the vibrio, the vibrio is also dominant in the culture water body after killing, and finally culture failure is caused.

The existing method for culturing the penaeus vannamei boone is difficult to effectively reduce the influence of vibrios no matter disinfection or beneficial microorganism adding, the bdellovibrio is specially adopted in the latest technology for aiming at the vibrios, but the bdellovibrio is often too strong in specificity and various in types, so that the using effect is very good in some places, and the normal production of the penaeus vannamei boone is influenced due to the fact that the vibrios are completely ineffective in some places.
