Abstract

Polyphenols are plant-derived compounds with known biological activities and potential health benefits. Over the past decade, there are an increasing number of studies have investigated the application of polyphenols and polyphenol-rich additives in aquaculture as functional feed additives. There are several types of polyphenolic compounds such as flavonoids, phenolic acids, lignans, and stilbenes of widely known beneficial influences on the overall performances and immunity of fish, and thereby improving the health status and production of fish farms. This review discusses the beneficial applications, optimum recommended dose, and potential side effects of these natural compounds on the growth performance, proximate body composition, immune responses, disease resistance, reproductive performance, and fillet quality of different fish species. Also, it points out that the biological functions and mechanisms associated with the polyphenolic compounds involved in the pathways of antioxidant and pro-oxidant activities, as well as the modulation of gene expression and different immune parameters. The output of this review article provided overwhelming evidence to support the claim that natural polyphenols can be considered as relatively safe and viable alternatives to synthetic chemical compounds that not only to improve the fish health status but also to enhance the fish quality, productivity, and food safety while reducing the use of chemicals and antibiotics in the aquatic eco-systems.

摘要

多酚是植物来源的化合物，具有已知的生物活性和潜在的健康益处。在过去的十年中，越来越多的研究调查了多酚和富含多酚的添加剂作为功能性饲料添加剂在水产养殖中的应用。存在多种类型的多酚化合物，例如类黄酮、酚酸、木脂素和芪，它们对鱼类的整体性能和免疫力具有广泛的有益影响，从而改善养鱼场的健康状况和生产。本综述讨论了这些天然化合物对不同鱼类的生长性能、近似体成分、免疫反应、抗病性、繁殖性能和鱼片质量的有益应用、最佳推荐剂量和潜在副作用。还，它指出了与参与抗氧化和促氧化活性途径的多酚化合物相关的生物学功能和机制，以及基因表达和不同免疫参数的调节。这篇评论文章的结果提供了压倒性的证据来支持这样的说法，即天然多酚可以被认为是合成化合物的相对安全和可行的替代品，不仅可以改善鱼类的健康状况，还可以提高鱼类的质量、生产力和食物。安全，同时减少水生生态系统中化学品和抗生素的使用。以及基因表达和不同免疫参数的调节。这篇评论文章的结果提供了压倒性的证据来支持这样的说法，即天然多酚可以被认为是合成化合物的相对安全和可行的替代品，不仅可以改善鱼类的健康状况，还可以提高鱼类的质量、生产力和食物。安全，同时减少水生生态系统中化学品和抗生素的使用。以及基因表达和不同免疫参数的调节。这篇评论文章的结果提供了压倒性的证据来支持这样的说法，即天然多酚可以被认为是合成化合物的相对安全和可行的替代品，不仅可以改善鱼类的健康状况，还可以提高鱼类的质量、生产力和食物。安全，同时减少水生生态系统中化学品和抗生素的使用。
