specific Embodiment approach 1
[0016] The method of the present invention comprises the following steps: step 1, utilize the method for siphon, fish excrement is collected in the aseptic container, add aseptic physiological saline to dissolve it, the ratio of fish intestinal excrement and sterile water is 1: 10. Filter the dissolved fish intestinal feces mixture through sterile ordinary qualitative filter paper to filter out solid residues. The filtered liquid is placed in a pre-sterilized open square tank. The square tank depends on the specific fish. The size setting; the amount of bacterial solution added to the square tank depends on the size of the fish that needs to be put in, and it is enough to cover the fish;
[0017] Step 2: Add filter-feeding silver carp or silver carp into the square tank, the addition ratio is 10-20 fish / m 3 Water body, oxygenated to keep silver carp healthy and alive, and filter-feeding fish kept in the container for 10-20 days;
[0018] Step 3. Carp, grass carp, crucian carp...
Embodiment approach
[0020] The implementation method includes the following steps: Step 1, which is the same as the specific embodiment 1;
[0021] Step 2. Carp, grass carp, and crucian carp suffering from bacterial diseases are treated at a rate of 5 to 10 fish / m 3 The water body is placed in a square tank and cultured for 10 to 20 days.
specific Embodiment approach 3
[0023] The implementation method comprises the following steps: step 1, select a square tank of the same size as that in the specific embodiment 1, add filter-feeding silver carp or silver carp, and the addition ratio is 10 to 20 tails / m 3 Water body, oxygenated to keep silver carp healthy and alive, and filter-feeding fish kept in the container for 10-20 days;
[0024] Step 2. Carp, grass carp, and crucian carp suffering from bacterial diseases are treated at a rate of 5 to 10 fish / m 3 The water body is placed in a square tank and cultured for 10 to 20 days.

Abstract
The invention relates to a method of transplanting healthy fish intestinal feces and treating ill fishes. The method comprises the steps of S1, collecting healthy fish intestinal feces, adding the collected feces into stroke-physiological saline solution for dissolution, stirring the solution evenly, filtering the solution, placing the filtered healthy feces bacteria fluid into a vessel, S2, adding filter-feeding fishes in the vessel, wherein the mass of each fish is about 50 g, the adding quantity is 10-20 fishes per cubic meter of water body; supplementing oxygen into the water to keep the filter-feeding fishes alive, breeding the filter-feeding fishes in the vessel for 10-20 days continuously, S3, adding fishes inflicted with intestinal bacterial diseases into the vessel based on the quantity of 5-10 fishes per cubic meter of water body, and breeding for 10-20 days. According to the method of transplanting healthy fish intestinal feces and treating ill fishes, the transplantation of health fish intestinal bacteria can improve intestinal microbiome of the ill fishes, the survival rate of the ill fishes are obviously increased, and therefore the method is applicable for large scale application.
Description
technical field [0001] The invention relates to the field of fish farming, in particular to a method for treating diseased fish by transplanting intestinal feces of healthy fish. Background technique [0002] In recent years, research on human gut microbes has become a hot spot, and many studies have found that human gut microbes are closely related to human diseases, health and growth. The Human Gut Microbiome Project is considered the second genome project. Gut microbes in other animals have been less studied than those in humans. [0003] The research on fish gut microbes is still in its infancy, and there are few studies on the correlation between the composition and species of gut microbes and the growth, nutrition, and immunity of fish itself. At present, researchers have promoted the growth of fish and improved the immunity of fish by adding nutrients, immune enhancers, and Chinese herbal medicines to fish feed. However, there is no way to improve the survival rate...
