Mozambique tilapia (Oreochromis mossambicus) gut and water 16s rDNA sequencing. aquaculture metagenome

Cadmium is a highly toxic heavy metal known for its persistence and bioaccumulative nature. Aquatic ecosystems play a vital role in supporting diverse forms of life and maintaining ecological balance. It enters aquatic environments through a range of sources, such as industrial discharges, mining activities, and the use of Cd-based products. The Mozambique tilapia was exposed to cadmium for 4 months. After that, the gut stool was collected for 16s rDNA sequencing. The aim of this study was to understand the mechanisms of cadmium toxicity to the health of the fish gut. The results revealed that the low concentration of cadmium was also highly toxic to fish health.

镉（Cadmium）是一种具有持久性与生物累积性的剧毒重金属。水生生态系统在支撑多样生命形式、维持生态平衡中发挥着至关重要的作用。镉可通过工业排放、采矿活动以及含镉产品使用等多种途径进入水生环境。本研究将莫桑比克罗非鱼暴露于镉环境中长达4个月，随后收集其肠道粪便样本进行16S rDNA测序。本研究旨在揭示镉对鱼类肠道健康的毒性作用机制。研究结果显示，即便低浓度的镉也会对鱼类健康造成严重毒害。
