Freshwater fishes are exposed to diverse environmental conditions and microbial communities that may influence their health and susceptibility to bacterial infections. Bacterial diseases can produce visible pathological manifestations and significant physiological changes in infected fish. The present study investigated bacterial infections and their pathological and haematological effects in selected freshwater fishes of the Mula–Mutha River, Pune District, Maharashtra. Fish specimens representing selected freshwater species were examined for clinical abnormalities, and samples from affected fish were subjected to bacteriological investigation. Bacterial isolates were characterised using standard microbiological and biochemical procedures. Haematological parameters, including haemoglobin (Hb), red blood cell (RBC) count, white blood cell (WBC) count, packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC), were compared between apparently healthy and infected fish. Selected physicochemical parameters of river water were also assessed. The statistical analysis demonstrated highly significant differences in Hb, RBC, WBC and PCV between healthy and infected fish (p < 0.0001), while MCV showed a significant difference (p = 0.0178). MCH and MCHC did not differ significantly. The findings indicate substantial haematological disturbance associated with bacterial infection and provide baseline information on fish health in the Mula–Mutha River ecosystem.
KEYWORDS
The present investigation provides an integrated assessment of bacterial infection, clinical pathology and haematological responses in selected freshwater fishes of the Mula–Mutha River, Pune District, Maharashtra. Infected fishes exhibited marked reductions in Hb, RBC and PCV and a substantial increase in WBC. These differences were highly significant (p < 0.0001), while MCV also differed significantly (p = 0.0178). MCH and MCHC did not show significant differences. The findings indicate substantial physiological and immune responses associated with bacterial infection and provide useful baseline information for fish-health monitoring in the Mula–Mutha River ecosystem.
