Embodiment 1

[0039] Preparation and application effect of curing agent in Hainan region of embodiment 1

[0040] Location: Wenchang City, Hainan Province

[0041] Wenchang, Hainan belongs to the red clay soil. Changsa and Wengtian often appear like "red water" or muddy water. The acidity of newly dug ponds is related to the soil type. The main reason is that the oxidation and hydrolysis of soil minerals make the water sour, thus "Red water" or muddy water appears. Tilapia is mainly cultured, with an average yield of 2,200 catties / mu, and there are few or no algae dominant communities in the pond.

[0042]In Wenchang City, including Changsa Town and Wengtian Town, a fish pond in Wengtian Town was selected as a representative high-yield fish pond. The number of occurrences in this fish pond within one year was 0, and the main breeding tilapia was 3570 catties. per mu (the average output of local tilapia fish ponds is 3,000 jin / mu), and the ponds are rich in algae, such as Scenedesmus chloro...

Embodiment 2

[0071] Preparation and application effect of embodiment 2 Jiangsu Yancheng maintenance agent

[0072] The fish ponds near the coast of Yancheng, Jiangsu Province are large ponds ranging from tens to two hundred mu, and adopt the polyculture model. Grass carp is mainly cultivated, with an average yield of 1,500 catties / mu, and there are few or no algae dominant communities in the pond. After investigation, the fishpond in Huachen Base, Dafeng Port, Dafeng District, Yancheng was selected as a representative high-yielding fishpond. The number of disease cases in this fishpond was 0 within one year, and the main breeding grass carp was 2,500 catties / mu (local average breeding Grass carp ponds have a yield of 2,000 catties / mu), and the ponds are rich in algae, such as Chlorella and Scenedesmus.

[0073] 1. Preparation of enrichment culture of indigenous microbial flora

[0074] Take the middle water of a representative high-yield fish pond (the depth of the fish pond is about 1m, ...

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...
