Abstract

The invention relates to a fermented product composition for lowering levels of ammonia nitrogen and nitrite nitrogen in a prawn pool and a preparation method thereof. The method comprises the steps: 1) separately and uniformly mixing and stirring 60-80% of cassava starch, 10-20% of zeolite powder, 2-15% of EM (effective microorganism) stock solution and 5-10% of yucca extract; 2) mixing the mixed raw materials with water in a weight percentage of (1:5)-(1:7), and uniformly stirring; and 3) transferring the mixture of the mixed raw materials and pool water to a sealed container, and fermenting for 24 hours. The fermented product composition provided by the invention can supplement the nutritional requirements of the prawn, and simultaneously can significantly improve the carbon / nitrogen ratio in a water body of a prawn aquaculture pool at middle and later periods, thereby promoting the conversion of ammonia nitrogen and nitrite nitrogen in the water body and improving the health levelof the prawn.

Description

technical field [0001] The invention relates to a preparation capable of reducing the levels of ammonia nitrogen and nitrite nitrogen in water, belonging to the technical field of aquaculture, in particular to a fermentation product composition capable of reducing the levels of ammonia nitrogen and nitrite nitrogen in prawn ponds and a preparation method thereof. Background technique [0002] Shrimp is a pillar species of my country's aquaculture industry. It has developed rapidly in recent years. By 2010, the aquaculture area will exceed 5 million mu and the output will exceed 1 million tons. However, the shrimp farming industry is also facing a very serious disease crisis while developing rapidly. At this stage, the intensive culture of prawn ponds in my country mostly adopts the culture structure of "three ponds in one". The aquaculture pond is not only a metabolic pond for prawns, but also a pond for feeding prawns, as well as an oxidation and decomposition pond for org...
