研究了重金属镉、砷和锌亚致死暴露45 d对印度主要鲤鱼（Labeo rohita、Cirrhus mrigala和Catla catla）的影响。重金属处理的一般表现出显着减少碳水化合物和脂肪含量的含量在肌肉中，以及在鳃在所有三种鱼。不同处理对鱼体和鳃中碳水化合物和脂肪含量的影响顺序为：Cd+As+Zn>Cd+As>As+Zn>Cd+Zn>Cd>As>Zn。当鱼被转移到无金属的水30天，碳水化合物和脂质含量的水平显着改善在所有三种鱼。
Studies were conducted to assess the effects of sublethal exposure of heavy metals cadmium, arsenic and zinc for 45 days on Indian major carps, Labeo rohita, Cirrhinus mrigala and Catla catla. Heavy metal treatments in general showed significant reduction in carbohydrate and lipid contents content in muscles as well as in gills in all the three fish species. The order of reduction of muscle and gill carbohydrate and lipid content due to different treatments was Cd+As+Zn>Cd+As>As+Zn>Cd+Zn>Cd>As>Zn. When fish were transferred to metal free water for 30 days, the level of carbohydrate and lipid contents improved considerably in all the three fish species.
