The Application Of The Little Electrolysis Technique Of The Nanocatalyst In Aquatic Animal Disease Prevention And Control

With the rapid development of aquaculture，aquaculture has gradually become large-scale、intensification、 industrialization， therefore bringing the situation of serious pollution ofaquaculture water and frequent occurrence of aquatic animal diseases. The issue of aquaticproducts quality and safety has always been plagued by the sustainable development ofaquaculture and affected the product’s competitiveness in the market which caused seriouseconomic losses, and the safety consciousness of aquatic products is enhanced continuously, soaquatic disease has become an important factor restricting the development of aquaculture in the21st century.This test used the effect study that the little electrolysis of the nanocatalyst kills seawaterbacteria in aquaculture, and that electrolysis seawater removed chlorine cultivates biological feedof aquatic animal fingerlings (such as unicellular algae, rotifers) and Penaeus vannamei、Grouperto explore the role of the micro electrolysis in aquatic animal disease prevention and control,providing the basis for the drug abuse and disease control in aquaculture. The main results are asfollows:The killing effects of the little electrolysis of the nanocatalyst to bacteria in seawater, thetest results showed: The little electrolysis of the nanocatalyst could substitute the traditionalchemicals and antibacterial agent to kill and suppress bacteria in seawater and electrolysis ofwater efficiently and thoroughly; The size of bacteria killing rate was proportional toelectrolytic processing equivalent, when processing equivalent (D)≧24.65w.h/t, thesterilization rate reached100%in processing seawater and sterilization ability could last for48hours at least.The effect of the little electrolysis seawater removed chlorine cultivating biological feedof aquatic animal fingerlings (such as unicellular algae, rotifers) and Penaeus vannamei、Grouper,the test results showed: When processing equivalent was in24.65-41.20W·h/t range，the little electrolysis seawater was better than disinfectant seawater in actual production to trainunicellular algae and rotifers,and training seawater and individual found no pathogens and thematerial of suspected pathogens in the case of not putting on drug; In terms of processingseawater, micro production cost（0.012-0.026元/t）was far lower than the normal productioncost(0.11-0.126元/t).The effect of the little electrolysis technique of the nanocatalyst seawater removed chlorinethat cultivating Penaeus vannamei and Grouper,the test results showed:When processing equivalent ranged form40W·h/t to66.86W·h/t， micro processing water was better thandisinfectant water to cultivate Penaeus vannamei in gowth process and rate of emergence,besides individual health and non-medicine residual; In the process of cultivating grouper, therewas not bacteria disease and seawater quality keep good combined with changing the water andabsorption sewage when processing equivalent was in66.86W·h/t, but the low temperatureinfluence the development and survival of fish in the early cultivation and led to low survivalrate；Research group will be developed。The test proves that the little electrolysis water of the nanocatalyst is better than traditionaldisinfect water in aquiculture. The little electrolysis technology of the nanocatalyst can beapplied to the cultivation of Penaeus vannamei and Grouper combined with the cultivation of thechlorella and rotifers and advanced nursery and breeding technique, which can controleffectively the appearance of pathogenic diseases and incubate high quality and health fry, has awide application prospects In aquaculture disease control and prevention...
