光是一个比较复杂的外部生态因子,包括光谱、光照强度和光周期。光在水生环境中具有特殊的特征。鱼 对光变化的感受性随着鱼种类以及发育水平的不同而不同。水生动物的摄食、生长、发育以及存活等都直接或者间接 受到光的影响。主要综述了光照对水生动物在这几方面的影响。
Light is a more complex external ecological factor, including spectrum, light intensity and photoperiod. Light has special characteristics in aquatic environment. The sensitivity of fish to light changes varies with the type of fish and the level of development. Aquatic animal feeding, growth, development and survival are directly or indirectly affected by light. The effects of light on aquatic animals in these aspects are mainly reviewed.
