Abstract

The invention discloses a method for culturing Chaetoceros lorenzianus Grunow through intermittent light with a two-step method and belongs to the field of aquaculture. Compared with a traditional technique, a formula of a Chaetoceros lorenzianus Grunow culture solution is more scientific and reasonable, the Chaetoceros lorenzianus Grunow is cultured through intermittent light in a volumetric flask and a universal flask with the two-step method, the Chaetoceros lorenzianus Grunow grows fast, the yield is high, the content of polyunsaturated fatty acid is high, equipment is simple, operation is flexible, washing is convenient, the cost is low, production is stable, the method is not affected by seasons, environment-friendly, energy-saving, convenient to operate and free from pollution, and the yield of Chaetoceros lorenzianus Grunow is increased by 80%.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for cultivating Chaetoceros rockini with an intermittent light two-step method. Background technique [0002] Chaetoceros rockii belongs to Diatomphyta, Central Class, Boxyphyta, Chaetoceroceae, and Chaetoceros. It is a small marine planktonic diatom with small cells, thin walls, and single life. It can grow and reproduce in an environment of 10-39°C, and the optimum temperature is 25-35°C. It is a coastal brackish water species. Compared with other algae, it reproduces quickly and is resistant to high temperature, and has higher polyunsaturated fatty acid content. Under good culture conditions, its eicosapentaenoic acid (EPA) accounts for 10.20% of the total fatty acid content. Chaetoceros lobei grows rapidly, especially in spring and summer, and often becomes the dominant group of phytoplankton. Therefore, its species composition and cell abundance have direct ...
