Abstract

The invention relates to a method for improving freshwater fish quality with beneficial microorganisms, belongs to the field of aquaculture microorganism application and aims to provide a microorganism application technical method for effectively improving freshwater fish quality. In 1-2 months before marketing of freshwater fish, cultured 'EM (effective microorganisms) are poured in an aquaculture water area every five days in sunny mornings on the conditions that the water temperature is above 15 DEG C and dissolved oxygen is not less than 3mg/L, so that abnormal taste of the freshwater fish under manual rich-water rearing conditions can be lessened to improve freshwater fish quality and increase aquaculture economic benefits. The method is technically simple, low in investment and risk, high in operability, simple to master and apply and easy to popularize.

Description

technical field [0001] The invention relates to an application technology of beneficial microorganisms in aquaculture, especially a method for improving the quality of freshwater fish by beneficial microorganisms "EM bacteria". Background technique [0002] In recent years, with the further development of freshwater fish farming in ponds, under high-density artificial breeding conditions, bulk aquatic products raised with artificial fertilizers and water have more or less peculiar smells, such as earthy smell, which directly affects freshwater fish. Quality affects commodity value and consumption, but high-quality bulk freshwater fish with good flavor and good quality are hard to find. [0003] Beneficial microorganisms "EM bacteria", whose main components include photosynthetic bacteria, yeasts, lactic acid bacteria, actinomycetes and fermentative filamentous fungi and more than 80 strains of 16 genera, are also widely used in China. Method for smelly rivers and lakes (Li ...
