Apelin与鱼类摄食

鱼类通过摄食活动获得能量和营养物质，而食欲是影响鱼类摄食的重要因素之一。食欲调控是一个复杂的网络，大脑整合机体能量和摄食信号，通过食欲调节因子（包括促进食欲因子和抑制食欲因子）调控鱼类摄食行为。Apelin作为一种新型内分泌因子，在体内发挥广泛的生物学作用。其中，apelin在摄食调节方面的作用正在引起学者的关注。本文以哺乳动物为参照，综述了apelin的组织分布、饥饿和营养物质对apelin表达的影响、apelin处理对鱼类摄食的影响及其可能的机制和信号通路，旨在为促进鱼类摄食和水产养殖提供参考。

Apelin and fish feeding

Fish obtain energy and nutrients through feeding activities, and appetite is an important factor affecting fish feeding. Appetite regulation is a complex network in which the brain integrates the body''s energy and feeding signals to regulate fish feeding behavior through appetite regulators, including orexigenic peptides and anorexigenic peptides. As a new endocrine factor, apelin plays a wide range of biological roles in vivo. Among them, the role of apelin in the regulation of food intake is attracting the attention of researchers. This paper reviews the tissue distribution of apelin, the effects of starvation and nutrients on apelin expression, the effects of apelin treatment on animal feeding, especially fish feeding, its possible mechanisms and signaling pathways, so as to provide references for promoting fish feeding and aquaculture.
