non-water exchange type culturing method for misgurnus anguillicaudatus using starch degrading enzyme as malt

摘要

Disclosed is a water-free culture method for loaches using malt starch degrading enzyme. The disclosed method for non-exchange culture of loach using malt starch degrading enzyme comprises: a) stocking step of putting loach fry into breeding water filled in a culture tank; b) a feed supply step of supplying feed to aquaculture tanks stocked with loach fry; c) Add a carbon source to breeding water to allow heterotrophic bacteria to grow, remove ammonia, a toxic substance in breeding water, supply starch, a polysaccharide as a carbon source, to breeding water, and add malt starch decomposing enzyme to breeding water By supplying treatment, the polysaccharide starch is slowly decomposed into monosaccharides by the starch-degrading enzyme and applied to the proliferation of heterotrophic bacteria, thereby preventing oxygen starvation for breeding water due to the rapid proliferation of heterotrophic bacteria, and a toxic substance. It is characterized in that it comprises a; breeding water management step to make the removal of ammonia.
