重金属镉作为生物体内非必需的微量金属,是重金属中毒性最强的元素之一.目前,我国水产养殖业中镉污染问题十分严峻,水体中镉浓度的增加会对水产动物的生长性能、抗氧化能力、免疫力等产生影响,通过食物链间接对食品安全和人类健康造成危害.目前,在饲料中添加营养物质是缓解水产动物镉胁迫的主要方式之一,涉及的营养物质主要包括微量元素、多糖、益生菌、酚类物质、维生素和含硫氨基酸等.本文综述了镉胁迫对水产动物的影响以及主要营养物质对镉胁迫的缓解作用,为通过添加营养物质来减少或消除镉胁迫对水产动物带来的负面影响提供参考,并为建立健康养殖技术提供更详细、更系统的科学依据.
Research Progress of Nutrients Alleviating Cadmium Stress in Aquatic Animals
As a non-essential trace metal,cadmium is one of the most toxic elements of heavy metals.At pres-ent,the problem of cadmium pollution for aquaculture in China is very serious.The increase of cadmium con-centration in the aquatic environment will affect the growth performance,antioxidant capacity,immunity of a-quatic animals,and indirectly cause harm to food safety and human health through the food chain.Adding nu-trients to the diet is one of the main ways to alleviate the cadmium stress,and nutrients include trace elements,polysaccharides,probiotics,proanthocyanidins,phenolic substances,vitamins,sulphur-containing amino acids and so on.This paper summarized the effects of cadmium stress on aquatic animals and the mitigating effects of different nutrients on cadmium stress.This work will provide a reference for reducing or eliminating the nega-tive effects of cadmium stress through nutrient supplementation,and provide a more detailed and systematic sci-entific basis for the establishment of healthy aquaculture technology.[Chinese Journal of Animal Nutrition,2024,36(9):5486-5496]
