Ecology process of controlling nitrite in fish and shrimp pond

Abstract

The invention is an ecological method of controlling nitrite in fish and shrimp pool, fixing helpful microbe particles on discarded crop stalks, then throwing these stalks in the bottom of the pool, so that the helpful microbes grow and breed by using surplus waste nitrogen in the pool and additional carbon source so as to eliminate harmful nitrite and amino nitrogen; simultaneously decomposes organic matters in bottom mud, and the helpful microbes themselves can act as the source of monocell protein of fishes and shrimps. It can not only implement resource utilization of the discarded matters but also promote ecological balance, implementing healthy breeding.

Description

technical field [0001] The invention relates to an ecological method for controlling nitrite in fish and shrimp ponds. Background technique [0002] Various wastes produced in the process of aquaculture, including bait residues, fish and shrimp excrement, dead biological residues, medicines, fertilizers, etc., accumulate, decompose and transform in the pond, forming a large number of toxic substances to fish and shrimp. Various substances, such as nitrite, hydrogen sulfide, methane, ammonia nitrogen, nitrogen oxides, etc., deteriorate the water quality and threaten the survival and normal growth of farmed animals. Especially under the conditions of high-density and intensive aquaculture, the nitrite content in the water body is often seriously exceeded, resulting in nitrite poisoning and the death of fish and shrimp, which has become a prominent and urgent problem in aquaculture. [0003] Nitrite is an intermediate product of various biochemical rea...
