The present study aimed to evaluate and compare the toxicity level of dietary and waterborne Cadmium (Cd) source on the Goldfish Carassius auratus (C. auratus) using various biochemical and microscopic shreds of evidence. C. auratus were divided into two groups based on Cadmium supplementation methods subjected to the same concentrations in the diet and water; moreover, control (Ctrl) group was set up for comparison. Dietary supplemented group (DSG) group and (Aqueous supplemented groups) ASG were supplied with 0.5% of the Cadmium. Successful completion of the study resulted in the lucrative outcomes, and we noticed significantly high concentrations of Cadmium in the gills of the ASG fish while considerably low levels in the gills of DSG. Histopathological evidence showed clear and distinct changes in the liver cells, dilated sinusoids and unusual occurrence of Kupffer cells were noticed in the AS group fish. At the same time, there were also noticeable changes in the DS group compared to CTRL. Visible changes can be seen on the outer morphology of gills, lamella of ASG and DSG both were shrunk and broken, similar changes were noticed in the muscles myoepithelium. The stress parameters were differentially expressed in both the groups; waterborne Cadmium caused a pronounced release of AST, ALT, cortisol, and glucose concentrations. Comparative mortality showed the highest death rate in the ASG fish compared to DSG fish. The present study depicts the highest toxicity of Cadmium in the soluble Addendum form moreover, administered route and time length are crucial factors.

使用显微镜和生化技术评估镉的毒性及其对金鱼（Carassius auratus）的可能影响。

本研究旨在使用各种生化和显微证据来评估和比较饮食和水性镉 (Cd) 源对金鱼鲫鱼( C. auratus )的毒性水平。金龟子根据饮食和水中相同浓度的镉补充方法分为两组；此外，还设置了控制（Ctrl）组进行比较。膳食补充剂组 (DSG) 组和（水性补充剂组）ASG 供应 0.5% 的镉。该研究的成功完成带来了丰厚的结果，我们注意到 ASG 鱼鳃中镉的浓度显着高，而 DSG 鱼鳃中的镉含量相当低。组织病理学证据显示，在 AS 组鱼中，肝细胞有明显的变化、扩张的血窦和库普弗细胞的异常出现。同时，与CTRL相比，DS组也有明显的变化。在鳃的外部形态上可以看到明显的变化，ASG和DSG的薄层均出现收缩和断裂，肌肉肌上皮也有类似的变化。两组的应力参数表达不同；水性镉导致 AST、ALT、皮质醇和葡萄糖浓度的显着释放。与 DSG 鱼相比，比较死亡率显示 ASG 鱼的死亡率最高。本研究描述了可溶性附录形式中镉的最高毒性，此外，给药途径和时间长度是关键因素。与 DSG 鱼相比，比较死亡率显示 ASG 鱼的死亡率最高。本研究描述了可溶性附录形式中镉的最高毒性，此外，给药途径和时间长度是关键因素。与 DSG 鱼相比，比较死亡率显示 ASG 鱼的死亡率最高。本研究描述了可溶性附录形式中镉的最高毒性，此外，给药途径和时间长度是关键因素。
