Abstract

The invention relates to an aquaculture composite microbial agent, which comprises the following agents by weight: 5-10 parts of Bacillus subtilis, 0.5-4 parts of Bacillus licheniformis, 1-6 parts of bacillus megaterium, 0.2-1 part of Pseudomonas gelatinasa, 0.5-3 parts of Rhodopseudomonas capsulata, and 2-8 parts of Bdellovibrio bacteriovorus. The invention also relates to application of the aquaculture composite microbial agent in improvement of water quality and / or control of aquatic organism diseases.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an aquaculture compound microbial bacterial agent and an application thereof. Background technique [0002] my country is one of the largest aquaculture countries in the world. In many areas of our country, aquaculture has become an important source of income for local farmers. Since the vigorous development of the intensive aquaculture model in our country, it has solved the problem of relative shortage of natural fishery resources, but at the same time it has also caused great pressure on the water environment of most rivers and lakes in our country, seriously restricting the development of aquaculture in our country. sustainable development. For example, the decomposition of organic matter such as biological debris consumes a large amount of dissolved oxygen, resulting in anoxia at the bottom, and at the same time releases some harmful substances, such as ammonia nitrogen, nitrite,...
