Study on alteration of critical water quality parameters and selected metabolic response of Labeo rohita fingerling subjected to transportation stress.

Abstract

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 T, (1g glucose+2g sodium chloride)/L, T2 (2g glucose + 2g sodium chloride)L, T3 (1g glucose + 4g sodium chloride)/L, and T4 (2g glucose + 4g sodium chloride)/L along with a control group, an experiment was conducted in triplicate, Before and after 12h 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 significanlty (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 increase the survival rate of the IMC. Labebo rohita fingerlings after the trasportation.
