Description

A kind of method of stereo ecological Polyculture associating prevention and control Hepatopancreatic necrosis disease and white spot syndrome
Technical field
The present invention relates to a kind of method of stereo ecological Polyculture associating prevention and control Hepatopancreatic necrosis disease and white spot syndrome, belong to technical field of aquaculture.
Background technology
Shrimp culture industry is China's mariculture pillar industry, and the eighties in last century starts fast development, and produce per year and continue to rise, annual production so far maintains about 1,300,000 tons.But breeding density constantly increases, breeding environment worsens, disease incidence height etc. more highlights drawback day.Shrimp disease problem remains the Main Bottleneck of shrimp culture industry development.The major measure of current solution shrimp disease problem comprise improve prawn resistance against diseases, improve shrimp culture environment and cut off the route of transmission etc. of disease of prawn cause of disease several.Since prawn white spot syndrome (WhiteSpotSyndrome, WSD) outbreak of epidemic in 1992, a kind of practical ways have not worldwide still been found thoroughly to prevent the outbreak of epidemic of prawn white spot syndrome.In recent years the Hepatopancreatic necrosis disease (hepatopancreaticnecrosisdisease, AHPND) broken out inflicts heavy losses on shrimp culture industry again.The outbreak of epidemic of disease causes serious economic loss to the shrimp culture industry of China, and according to estimates, annual economic loss is up to 3,000,000,000 yuan.
Owing to pursuing high production, the breeding way of prawn develops into high density culture by low-density putting in a suitable place to breed, shows as high investment, and cultivation density strengthens, and increases the feed and drug use amount thrown in, increases the aquaculture model of quantity of exchanged water.The cultivation amount of unit of water body increases, and excreta, the remaining bait of generation must increase.Because the species of culturing pool are single, the ecosystem is very fragile, once cultivation amount exceedes the ecological ability to bear of culturing pool, it is inevitable that the ecosystem worsens.Ammonia-nitrogen content raises, bacteria breed, and harmful algae breaks out, and along with the ecosystem worsens, various disease will break out thereupon.The comprehensive infection of hepatopancrease that Hepatopancreatic necrosis disease is the bacterium of prawn hyperphagia, viral inclusion body causes.Hepatopancreatic necrosis disease occurs in the more early stage of cultivation.White spot syndrome is caused by white spot syndrome virus, mainly by prawn ingest die of illness shrimp infect.Environmental deterioration makes prawn be in emergency rating always, causes physique to die down, immunity degradation, once environment changes, potential virus disease is more easily broken out.
Fish-shrimp mix-culture effectively can prevent and treat prawn disease, its principle is different because raising together with fish ecological habit difference, filter-feeding fish and ominivore-fish can filter food hydroplankton, organic suspended matter, bacterial aggregate etc., remove the organic debrises such as residual bait, ight soil, biological corpse, thus play control plankton excessive multiplication, reduce the oxygen demand of non-cultivation object, keep stablizing of Chi Shui, for prawn growth provides good water quality environment.Predacious fish can eat up the sick and weak shrimp in pond, also can chase shrimps, produces " Catfish Effect ", ensures the vigor of pond shrimp, improves immunity, reaches protection effect, effectively controls Fast-propagation and the propagation of pathogene.The research of existing Fish-shrimp mix-culture at present, such as Chinese patent CN101622962A, CN103430882A, CN102771422A and CN103621448A etc.
