| Summary: | Heavy metal (HM) contamination poses a substantial risk to both aquatic ecosystems and the environment. Therefore, this investigation explored the potential recuperative effects of dietary turmeric (TU) and ginger (GN) on silver carp (Hypohthalmichthys molitrix) fingerlings. These fingerlings were exposed to mixtures of HMs, specifically Pb (1.71 mg/L), Cd (2.47 mg/L), Cr (0.1 mg/L), and Zn (0.4 mg/L), and evaluated for growth, hematology, carcass composition, hepatic antioxidant indices, and histopathological profile. A total of 210 fish (7.16 ± 0.01 g/fish) were randomly divided into seven groups, each in triplicate. Fingerlings were allocated to negative control (without HM), positive control (with HM), and five treatment groups (T1-T5). The treatment groups fed diets supplemented with 1 % TU, 1 % GN, 1 % TU+HM, 1 % GN+HM and combination of 1 % TU and GN + HM, respectively. Waterborne HM mixture negatively affected the growth performance, carcass, blood indices, antioxidant enzymes and histopathology. In contrast, fish groups fed with alone TU and GN supplementation resulted in increased growth, hematological indices, crude protein levels, and antioxidant enzyme activity of H. molitrix. In addition, GN, TU, and their combination supplementation with HM recuperated the above-mentioned parameters. Moreover, degeneration of hepatocytes, necrosis, and central vein damage were observed in HM-exposed fish and improved in the T3, T4, and T5 groups. The research findings demonstrated that feeding canola meal supplemented with 1 % GN, TU, or their combination to H. molitrix mitigated HM-induced negative effects on growth, carcass composition, antioxidant activity, hematology, and histopathological alterations in the liver. Conclusively, herbal supplements such as GN and TU exhibit promising benefits for promoting overall health and mitigating HM toxicity in silver carp. |
