Green healthy controllable industrial prawn culture method

Abstract

The invention discloses a green healthy controllable industrial prawn culture method. The method includes the steps of establishing an indoor circulating water treatment culture system, culturing beneficial microbial communities to enable the same in a raceway pond to reach the density enough to inhibit harmful vibrios, releasing young prawns, feeding different kinds of bait correspondingly according to the prawn sizes in different periods during culture, strictly detecting data change of water quality indexes every day, making a water transfer scheme, randomly detecting prawn bodies and the vibrio number in a water body once every three days, and making a microbial liquid concentration adjusting scheme according to the change so as to inhibit microbes by microbes. The green healthy controllable industrial prawn culture method has the advantages that a circulating water system is used for filtering large-particle organic matter and controlling nitrite in culture water, excrement and residual bait are decomposed and treated by the beneficial microbial communities, forbidden drugs such as antibiotics are not added in the whole process, zero water change and drainage is achieved, and accordingly the method is lower in environmental pollution, saving in water resource, short in culture cycle, high in profit level and capable of obtaining healthy pollution-free prawns.

Description

technical field [0001] The invention relates to the technical field of prawn cultivation, in particular to a method for healthy cultivation of prawns in indoor circulating water. Background technique [0002] In recent years, the development of Penaeus vannamei aquaculture has been difficult, and the success rate of outdoor large pond aquaculture is getting lower and lower. The current aquaculture models in earthen ponds, high-level ponds, and winter sheds have a common feature of diseases during the aquaculture process. Constantly, more and more sources of pathogens come from the surrounding seawater environment, and imitations of banned drugs such as antibiotics emerge in endlessly in the industry. At the same time, due to the high breeding density, large amount of bait, and a lot of metabolic waste in the artificial culture of prawns, the culture water is eutrophic The phenomenon of globalization is becoming more and more serious, and the vast majority of shrimp farms (in...
