Abstract
The current exploration pointed towards the impacts of non-essential heavy metals in estuarine catfish Mystus gulio. 30 days of exposure in the sublethal concentration of cadmium chloride Cd: 6.2 mg/L shows the effects in haematological, biochemical alterations and immune responses in fish. Fish exposed to 96hrs LC50 in 620 ppm of 1/10th sublethal concentration of CdCl2 in the periods of 30 days were reported. The results showed the cadmium concentration in M.gulio was subjected to the exposure of time duration. The analyzed boundaries are hemoglobin (Hb), red blood cells (RBC), white blood cell count (WBC), haematocrit (HT), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), platelets (PLT) and monocytes (Mon), lymphocytes (Lym). WBC and MCV were significantly increased whereas Hct, Hb, MCH, MCHC, RBC, PLT, Lym, and Mon (P<0.05) were drastically decreased when compared to the control fish. In biochemically trace differences in albumin (Alb), total protein (TP), total glucose (TG) and immunoglobulin M (IgM). IgM esteems were raised in experimental fish (P<0.05). It is clear abundantly that toxic heavy metals induce an early immunity response in the long whiskers’ catfish. Overall impressions can be auxiliary to low focuses on sublethal concentrations stimulating the stress responses in infected fish. In this study haematological parameters, biochemical and immune responses showed the alterations in functionally as well as structurally affecting innate immune responses of the brackish water fish Mystus gulio has been analyzed to the impact of cadmium chloride toxicity.
