Abstract

The gill is an important organ in fish that is involved in various physiological functions, including respiration, filter-feeding, ammonia nitrogen excretion, and osmoregulation. The physiological functions of gills are closely related to their structure, external feeding conditions, and environmental factors. Herein, we first briefly summarize the basic structure and functions of the gills of teleosts, then explain the structure and function of the gill barrier (as a microbial barrier, a chemical barrier, a physical barrier, and an immune barrier) in detail. Finally, we introduce the regulation of fish gill barrier health by ubiquitous feeding factors and environmental factors, and provide an outlook on the prospects of gill barrier health. We found that improving health through modulating feed factors is more convenient than improving environmental factors. This review increases our understanding of how nutrient composition and level in fish diet influences gill health and overall growth performance of fish.

硬骨鱼鳃屏障的结构、功能及调控研究进展

鳃是鱼类的一个重要器官，参与各种生理功能，包括呼吸、滤食性、氨氮排泄和渗透调节。鳃的生理功能与其结构、外部饲养条件和环境因素密切相关。在此，我们首先简要总结了硬骨鱼鳃的基本结构和功能，然后详细解释了鳃屏障（作为微生物屏障、化学屏障、物理屏障和免疫屏障）的结构和功能。最后，我们介绍了普遍存在的饲养因素和环境因素对鱼类鳃屏障健康的调节，并对鳃屏障健康前景进行了展望。我们发现，通过调节饲料因素来改善健康比改善环境因素更方便。这篇综述加深了我们对鱼类饮食中营养成分和水平如何影响鱼类鳃健康和整体生长性能的理解。
