The changes in physico-chemical characteristics of ambient water during transportation of fish causes stress and mortality. In this prelude, the present investigation involved the measurement of Physico-chemical characteristics of water (TAN, pH, and dissolved oxygen), biochemical parameters (serum total protein; serum glutamic-oxaloacetic transaminase, SGOT) during simulated transportation of Labeo rohita fingerlings using water additives. Four treatments of water additives were used in combination as T1 (1g glucose + 2g sodium chloride)/L, T2 (2g glucose + 2g sodium chloride)/L, T3 (1g glucose + 4g sodium chloride)/L, and T4 (2 g glucose + 4g sodium chloride)/L along with a control group, an experiment was conducted in triplicate. Before and after 12 h transportation, water quality and serum sampling were carried out. The analysis of the water quality parameters and serum sample showed a significantly higher (p<0.05) level of total ammonia nitrogen, lower pH, lower serum total protein, and higher SGOT activity in the control group after transportation. Whereas, a significantly (p<0.05) lower stress response and water quality values were observed in the treatment group indicating the potency of water additives in ameliorating the transportation stress, and in turn increases the survival rate of the IMC, Labeo rohita fingerlings after the transportation.
HIGHLIGHTS
• Transportation stress causes a significant alteration of water quality and serum biochemical parameters.
• Use of water additive (1g glucose+ 4g sodium chloride) provides higher survival and lower stress response during transportation.
