海洋浮游生物是海洋中大型生物或其幼体的饵料,它们处在“食物塔”的最低层,其数量的变化状况将直接涉及到渔业发展的前景。在海洋中,它们的生物量最多,单位体积的表面积最大,与海水接触密切,当海水受污染时,首先遭遇的就是这些饵料生物。海洋浮游植物是海洋初级产物的主要生产者,在光合作用过程中,能从海水中直接吸收各种元素 Marine plankton are the diets of the large organisms in the oceans or their larvae. They are at the lowest level of the “food tower.” The changes in their numbers will directly affect the prospects for the development of fisheries. In the oceans, they have the highest biomass, their largest surface area per unit volume, their close contact with seawater, and the first encounter with these sea creatures when they are contaminated. Marine phytoplankton, a major producer of marine primary products, absorbs various elements directly from seawater during photosynthesis
