钾是水产动物机体内的常量元素，也是维持生命不可或缺的必需物质。它在生物体的生理活动方面起着十分重要的作用，包括维持细胞电压、改变细胞膜电位和产生神经冲动。另外，钾还在氧化还原调节、酸碱平衡和新陈代谢过程中扮演着关键的角色。不同水产动物对钾的需求量不同，钾缺乏或者过量都会对动物机体产生不利的影响。本文主要针对钾在水产动物中的生理作用和营养代谢方面的功能展开综述。

Potassium is a constant element in aquatic animals and also essential to sustain life.Potassium is not only an important factor in physiological activities such as maintaining cell voltage, changing cell membrane potential and generating nerve impulse, but also plays a critical role in redox regulation, acid-base balance and metabolic process.Requirement of potassium differs among aquatic animals.Either dearth or surfeit will have deleterious impact.This article summarized the functions of potassium on physiological processes and nutrient metabolism in aquatic animals.
