The present study was performed to analyze the bioaccumulation of heavy metals, biochemical constituents, antioxidants, and metabolic enzymes in the crab Scylla serrata from different regions of Tuticorin, Southeast Coast of India. The study area consists of Threspuram and Harbour Beach which were polluted environments due to the discharge of industrial effluents and domestic sewage into them. Punnakayal, which is a low-polluted environment where the in-situ culture of S. serrata is carried out by local fish farmers, was selected as well. The results revealed that the level of heavy metals, biochemical constituents, antioxidants, and metabolic enzymes were significantly high in the crabs collected from Threspuram and Harbour Beach compared to the crabs collected from Punnakayal. This study indicates that crabs from polluted environments have significant heavy metals bioaccumulation which leads to elevated antioxidants and metabolic enzyme levels. This implies that the crabs are under oxidative and metabolic stress.

本研究的目的是分析印度东南沿海杜提戈林不同地区的蟹Scyla serrata中重金属，生物化学成分，抗氧化剂和代谢酶的生物累积。研究区域由Threspuram和Harbor Beach组成，由于工业废水和生活污水的排放，它们被污染了。Punnakayal，这是一种低污染的环境，在其中S. serrata的原地培养由当地养鱼户进行，也被选中。结果表明，与从Punnakayal采集的螃蟹相比，在Threspuram和Harbor Beach采集的螃蟹中重金属，生化成分，抗氧化剂和代谢酶的含量显着较高。这项研究表明，来自受污染环境的螃蟹具有大量的重金属生物蓄积，从而导致抗氧化剂和代谢酶水平升高。这意味着螃蟹处于氧化和代谢压力之下。
