Stress Mitigating and Growth-Enhancing Effect of Dietary Vitamin E in Indian Major Carps Cultured in East Kolkata Wetlands, India

Abstract

Stress mitigation is one of the most challenging tasks in aquaculture. The East Kolkata Wetlands (EKW) is a complex of natural and human-made wetlands lying east of the city of Kolkata, West Bengal, India. The EKW forms one of the largest assemblages of sewage-fed fish ponds. The present study investigated the effects of dietary vitamin E on the growth performance and clinical biochemistry of Indian major carps (Labeo rohita, Labeo catla, and Cirrhinus mrigala) cultured in the EKW. The carps of the EKW were fed with vitamin E (DL-α-tocopherol acetate) at 100 mg kg feed−1 for 120 days. Vitamin E diet-fed carps exhibited better growth than the controls with L. catla and L. rohita showing maximum net weight gain and specific growth rate, respectively. A significant decline in haemoglobin, cortisol, glucose, alanine aminotransferase (ALT), aspartate transaminase (AST), lactate dehydrogenase (LDH), and ALT:LDH levels was noticed in vitamin E diet-fed carps. Haemoglobin, creatinine, ALT, AST, LDH, and ALT:LDH levels differed significantly among the carps. Cirrhinus mrigala was the most susceptible to environmental stresses of EKW among the three carps. Temperature, ammonia, phosphate, and biological oxygen demand were the major influencing water quality parameters. The levels of serum cortisol, glucose, ALT, and superoxide dismutase were significantly influenced by these water quality parameters. The results indicated the positive influence of vitamin E as an anti-stress nutrient in carps cultured in the EKW. Dietary vitamin E at 100 mg kg feed−1 reduced the impact of stress in carps and improved their growth performance.
