Abstract

The invention relates to a microecological preparation used for preventing and treating apostichopus japonicus putrid skin syndrome and a preparation method of the microecological preparation and belongs to the field of aquatic microorganisms. Active ingredients of the microecological preparation are thalli of bacillus megatherium H1 and extracellular metabolites of the bacillus megatherium H1; the bacillus megatherium strain is separated from intestinal tract excrement of apostichopus japonicus which is healthily cultivated in Penglai, Shandong, detection of safety, bacteriostatic activity and toxicity and artificial antagonistic vibrio splendidus experiments verify that the bacillus megatherium H1 is antagonistic to vibrio splendidus, young apostichopus japonicus is effectively protected, the bacillus megatherium H1 can be used for preventing and treating apostichopus japonicus 'putrid skin syndrome' caused by vibrio splendidus and survival rate of an apostichopus japonicus seedling protecting stage is increased.

Description

Technical field:

[0001] The invention belongs to the field of aquatic microorganisms, and in particular relates to a micro-ecological preparation and a preparation method for preventing and treating "rot skin syndrome" of sea cucumbers. Background technique:

[0002] Apostichopus japonicas Selenka (Apostichopus japonicas Selenka) farming has become one of the important pillars of my country's aquaculture industry because of its highest output value of a single species and an annual growth rate of 20%. In 2011, the breeding area of ​​japonicus in Shandong Province reached 53,000 hectares, with an annual output of 71,000 tons (more than half of the national total output), and an annual output value of 16 billion yuan. However, with the continuous expansion of sea cucumber breeding scale in recent years, various diseases have come one after another, seriously restricting the healthy and sustainable development of the industry. The "rotting skin syndrome" that occurs in the see...
