| Abstract | ||
| The present investigation aimed to determine the toxicological effects of silver nitrate and silver nanoparticle on hematological and biochemical parameters of the widely consumed Oreochromis niloticus. Adult specimens of Oreochromis niloticus were exposed to 4 ppm concentration against the ameliorative effect of Moringa and camellia leaves extract 10% (100g/l) for 28 days. Empirical data obtained were subjected to statistical analysis of variance (ANOVA) to test the effects of silver nitrate (AgB), silver nanoparticles (AgNPS), Moringa oleifera (MO), Camellia sinensis (GT). Silver nitrate and AgNPS showed significant decrease in red blood cell count (RBC’s), blood hemoglobin (Hb), hematocrit value (Hct), the mean values of mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), white blood cell count (WBC’s), lymphocytes (LYM), monocytes (MON), serum protein (total protein, albumin and globulin), glucose. While mean corpuscular hemoglobin concentration (MCHC), neutrophils (NEU), eosinophils (EOS), AST, ALT, ALP, urea, creatinine, Cholesterol (Chol), and Triglyceride (Trig) were significantly increased from the control values. Moringa and GT supplementations play a positive role in detoxification of AgB and AgNPs toxicity. The results suggest that AgB and AgNPs can negatively affect the hematology and physiology of fish. It was observed that the supplementation of MO and GT extract decreases the toxic effect of them. | ||
