The objective of this review is to synthetize knowledge of the relationship between metals and oxidative stress in aquatic crustaceans (mainly shrimp and crabs) to analyze antioxidant responses when organisms are exposed to metals because the direct metal binding to the active site of enzymes inactivates most of the antioxidant systems. This study reviewed over 150 works, which evidenced that: (i) antioxidant defense strategies used by aquatic decapod crustaceans vary among species; (ii) antioxidant enzymes could be induced or inhibited by metals depending on species, concentration, and exposure time; and (iii) some antioxidant enzymes, as superoxide dismutase increase their activity in low metal levels and time exposures, but their activities are inhibited with higher metal concentrations and exposure time.

本综述的目的是综合有关金属与水生甲壳类动物（主要是虾和蟹）中氧化应激之间关系的知识，以分析当有机体暴露于金属时的抗氧化反应，因为金属与酶活性位点的直接结合会使大部分酶失活。抗氧化系统。本研究回顾了 150 多项工作，这些工作证明： (i) 水生十足目甲壳类动物使用的抗氧化防御策略因物种而异；(ii) 金属可以诱导或抑制抗氧化酶，具体取决于物种、浓度和暴露时间；(iii) 一些抗氧化酶，因为超氧化物歧化酶在低金属水平和时间暴露下会增加它们的活性，但它们的活性会随着金属浓度和暴露时间的增加而受到抑制。
