Composition and bacteriostatic agent for preventing and treating diseases of mastacembelus armatus, feeding device of wild mastacembelus armatus and bionic maintenance method of wild mastacembelus armatus

The invention discloses a composition for preventing and treating diseases of mastacembelus armatus, a bacteriostatic agent, a feeding device for wild mastacembelus armatus and a simulated ecological maintenance method. The composition contains a component 1 and a component 2, wherein the component 1 and the component 2 are selected from two different traditional Chinese medicine compositions 1-4; the traditional Chinese medicine composition 1 consists of coptis chinensis and scutellaria baicalensis; the traditional Chinese medicine composition 2 is composed of gallnut and rheum officinale; the traditional Chinese medicine composition 3 consists of ginkgo leaves and honeysuckle flowers; and the traditional Chinese medicine composition 4 consists of radix sophorae flavescentis and cortex phellodendri. According to the bionic maintenance method for the mastacembelus armatus, obvious technical progress is achieved in the aspects of increasing the survival rate and the feed utilization rate, reducing pathogenic i
