Abstract

The invention discloses a lactic acid bacterium nutrient enhancer for holothurian culture. The total weight ratio of a lactic acid bacterium agent to nutrient fodder is 1:(2-10). A preparation method for the lactic acid bacterium agent comprises the following steps: collecting thalli after bacterium enrichment and washing are performed; then drying the thalli after the thalli are mixed with the nutrient fodder so as to obtain a final product with the water content of 2-5%. The lactic acid bacterium nutrient enhancer for holothurians, which is prepared through the method disclosed by the embodiment of the invention, is suitable for holothurian culture; the treating process is simple and time consumption is less; the preparation cost is lower than that of a traditional method; the powder is long in retention time and free of pollution. The lactic acid bacterium nutrient enhancer has important practical significance on holothurian culture on a large scale.

Description

technical field [0001] The invention mainly relates to the technical field of seafood disease detection, in particular to a seafood probiotic nutrition powder, in particular to a lactic acid bacteria nutrition enhancer for sea cucumber cultivation. Background technique [0002] my country has a vast sea area, superior natural conditions, and rich marine resources. But the degree of development and utilization is still very low. This also shows that my country has great potential in the development and utilization of marine resources. Liaoning sea area is an important treasure house of marine biological resources and fishery resources in China. It is rich in sea cucumbers, scallops, mussels, oysters, fish, shrimp and algae, etc., driving the development of marine economy. Strengthen multilateral and bilateral international cooperation in marine development, intensively develop and utilize sea area and island resources, rationally allocate advantageous marine industries, scie...
