Problems solved by technology

With the large-scale farming of Penaeus vannamei, there are currently the following problems: due to water pollution and virus infection, the incidence of Penaeus vannamei is high and the survival rate is low; the quality of the input bait is poor, and the excess bait cannot be removed in time, causing organic Pollution of aquaculture water quality; excessive application of disinfection and purification agents by aquaculture personnel, resulting in waste of resources and serious water pollution
All of the above have limited the development of Penaeus vannamei aquaculture

Abstract

The invention discloses a culture method for reducing a disease incidence of penaeus vannamei. The method comprises the following steps: step 1, building a pond and treating the pond: arranging an aerator, a bait throwing device and a water inlet and a water outlet in the pond, sterilizing and disinfecting the pond before cultivation, fertilizing bottom mud, and planting waterweeds at the bottom of the pond; step 2, performing throwing: throwing the disinfected penaeus vannamei larvae and ctenopharyngodon idellus fry; step 3, performing feed management: performing feed feeding for 3-4 times per day; and step 4, preventing diseases: inspecting the pond every day, observing water quality and activities of fishes and the penaeus vannamei, timely changing water and performing oxygenation, andapplying a mixed preparation of a traditional Chinese herbal medicine liquid and probiotics for 3-5 times per month. The invention provides the culture method for reducing the disease incidence of thepenaeus vannamei. According to the invention, through optimizing culture technologies, the residual feed is less, the resource utilization rate is high, the water exchange amount is less, and therefore outbreaks and epidemics of bacterial diseases and viral diseases are effectively inhibited; and the disease incidence of the penaeus vannamei is low, and the survival rate is high, so that the development of a culture industry of the penaeus vannamei is effectively promoted.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a culture method for reducing the morbidity of Penaeus vannamei. Background technique [0002] Penaeus vannamei, also known as Penaeus vannamei, belongs to the phylum Arthropoda, Crustacea, Decapod order, Swimming order, Penaeidae, and the genus Penaeus. Penaeus vannamei has thin shell and fat body, delicious meat, high meat content and rich nutrition. It is deeply loved by consumers and is an excellent desalinated cultured species. With the large-scale cultivation of Penaeus vannamei, there are currently the following problems: due to water pollution and virus infection, the incidence of Penaeus vannamei is high and the survival rate is low; the quality of the input bait is poor, and the excess bait cannot be removed in time, causing organic Pollution of aquaculture water quality; excessive application of disinfection and purification agents by aquaculture personnel, result...
