Aquaculture, specifically farmed fish, contributes to global aquatic fish stuff production. The present study systematically reviewed mercury levels in farmed fish. One hundred two scientific articles were found in four databases. Only seven were considered appropriate, and eleven articles were added. In total, 18 articles are eligible for this review. Papers determining Hg in farmed fish were reported in seven countries: China, Korea, Pakistan, India, Brazil, the USA, and Poland. Fifty species from farmed fish were evaluated worldwide, and Ctenopharyngodon idella Glass carp, Oreochromis niloticus Tilapia, and Hypophthalmichthys nobilis (synonym of Aristichthys nobilis) Bighead carp have registered the highest frequency. The mercury values found in fish from the production system were low. For the risk analysis, only India presented values within tolerable limits; however, Korea and Pakistan showed high values, indicating a potential risk of consuming protein from farmed fish in these countries. Therefore, farmed fish are not Hg-free but safer than fish in nature due to greater control of biotic and abiotic factors in ponds, thus contributing to sustainable, productive economic activity.
水产养殖，特别是养殖鱼类，对全球水产鱼类产品的生产有贡献。本研究系统回顾了养殖鱼类中的汞含量。在四个数据库中找到了102篇科学文章。仅7篇被认为合适，并补充了11篇文章。总共18篇文章符合本综述的要求。确定养殖鱼类中汞含量的论文来自七个国家：中国、韩国、巴基斯坦、印度、巴西、美国和波兰。全球范围内评估了50种养殖鱼类，其中草鱼、尼罗罗非鱼和鳙鱼出现的频率最高。生产系统中鱼类的汞含量较低。在风险分析方面，只有印度的汞含量值在可容忍范围内；然而，韩国和巴基斯坦的汞含量值较高，这表明在这些国家食用养殖鱼类蛋白质存在潜在风险。因此，养殖鱼类并非不含汞，但由于池塘中生物和非生物因素得到更好控制，它们比自然环境中的鱼类更安全，从而有助于可持续的生产性经济活动。
