Abstract
Background: Biofloc technology (BFT) is a resource-efficient aquaculture approach that supports water-quality management, nutrient utilisation and reduced environmental impact.
Aim: The present study aimed to evaluate the physiological health status of Labeo rohita reared under biofloc conditions through haematological and biochemical assessments and to examine the suitability of BFT for sustainable fish production in the tribal region of Sarguja, Chhattisgarh, India.
Methods: Labeo rohita fingerlings were cultured for 90 days in a biofloc-based aquaculture system under controlled management conditions. At the end of the experimental period, blood samples were collected and analysed using standard laboratory procedures. Haematological parameters, including haemoglobin concentration, erythrocyte count, leucocyte profile and platelet count, were determined. Serum biochemical parameters, including cholesterol, glucose, SGOT, SGPT, albumin and total protein, were also evaluated to assess metabolic and physiological status.
Results: The fish exhibited a haemoglobin concentration of 13.9 g/dL, an RBC count of 3.91 million/cumm, a total leucocyte count of 5,960 cells/cu.mm and a platelet count of 3.19 lakh/cu.mm, all of which were within the stated physiological reference ranges. Biochemical analyses showed serum cholesterol (11.2 nmol), glucose (41.2 mg/dL), SGOT (59.2 IU/L), SGPT (14.1 IU/L), serum albumin (19.3 g/dL) and total protein (52.3 g/dL), indicating normal metabolic function, satisfactory nutritional status and no evidence of marked physiological stress or hepatic dysfunction under the study conditions.
Conclusion: The observed haematological and biochemical profiles indicate that Labeo rohita maintained under biofloc conditions remained in good physiological health during the culture period. These findings suggest that BFT may be a suitable and resource-efficient aquaculture option for supporting fish production in tribal and semi-urban regions of Chhattisgarh.
