单细胞藻以其对环境适应能力强、生长繁殖快、不败坏水质、营养高、适口性好等人工合成饵料无法取代的优点而被广泛应用于海、淡水育苗的直接或间接饵料。持续高密度生产培育单细胞藻是保障各类苗种孵化培育成败的关键;而保持藻类持续高产的重要措施一是抑制污染对藻类的危害; Single-celled algae are widely used in direct and indirect sea-freshwater seedling breeding due to their merits of being able to adapt to the environment, rapid growth and reproduction, unbeaten water quality, high nutrition and good palatability. Continuous high-density production of single-cell algae is to protect the success of all types of seed hatching incubation key; and keep algae continuous production of important measures is to suppress the pollution of algae;
