Regionally cultured aquatic miniature organism nourishing agent and preparation method thereof

Abstract

The invention discloses a regionally cultured aquatic miniature organism nourishing agent and a preparation method thereof. The nourishing agent is composed of culture pond muddy water, an indigenous microorganism flora enriched culture medium, and a microorganism culture material; wherein the weight ratio of the microorganism culture material to the culture pond muddy water is 1: (0.6-1); and the indigenous microorganism flora enriched culture medium accounts for 10 to 20% of the total weight of the microorganism culture material and the culture pond muddy water. The nourishing agent can optimize the diversity of miniature organisms in a culture pond. After using the nourishing agent, the pool nutrient type alga structure is converted into medium nutrient type alga structure composed of beneficial algae communities such as green alga. Moreover, the nourishing agent can reduce the death rate of fish, and the using amount of medicine is reduced. Moreover, the fish quality is improved, the yield of each mu is increased, the feed coefficient is reduced, the fish color becomes healthier, the taste becomes better, and the fish meat does not have any fishy smell and is tight.

Description

technical field [0001] The invention belongs to the technical field of ecological prevention and control of aquaculture diseases, and in particular relates to a maintenance agent for micro organisms in regional aquaculture water bodies and a preparation method thereof. Background technique [0002] Large-scale epidemics with regional characteristics often occur in the aquaculture industry. The common problem most closely related to the occurrence of the disease is the deterioration of the aquaculture water environment, and micro organisms such as microorganisms, protozoa, and algae in the water are the main objects of drug intervention. This has brought about a serious vicious circle, the balance of the water ecosystem has collapsed, and diseases have occurred one after another. Therefore, in the breeding process, some technologies and products have been formed to adjust the water quality and maintain the stability of the breeding water body. They mainly use microbial prepar...
