Biochemical studies in Muscle of fresh water fish, Labeo rohita (Ham.) exposed to heavy metals

The main aim of the present study is to know the effect of heavy metals in Tawa reservoir on Labeo rohita and their seasonal variations. During the study, Labeo rohita were exposed to pre monsoon, monsoon and post monsoon seasons at different sites in Tawa reservoir. The Protein quantity in muscle decreases when compared to the control (5.97±0.46 g/dl), pre monsoon (4.95±0.08 g/dl), monsoon (4.83±0.06 g/dl) and post monsoon (4.90±0.08 g/dl) periods. The Glucose quantity in muscle also decreases when compared with the controlled fish (91.47±1.17mg/dl), pre monsoon (88.61±0.28mg/dl) , monsoon (76.55±0.85mg/dl) and post monsoon seasons (86.58±0.59). The Lipid quantity of muscle also decreases during monsoon period (4.7±0.11mg/100ml) as compared to control (5.36±0.31mg/100ml), pre monsoon (4.93±0.12mg/100ml) and post monsoon seasons (4.76±0.08mg/100ml). The results are statistically significant at p< 0.005 level.
