Effect of suspended solid on survival, metabolic rate and blood chemistry of four different marine species

Abstract

The purpose of this study was to determine the effect of suspended solid (SS) on survival and metabolic rate of Sebastes schlegelii, Paralichthys olivaceus, Portunus trituberculatus and Charybdis japonicas, and blood chemistry of S. schlegelii and P. olivaceus under eight SS concentrations [0 (control), 10, 20, 30, 40, 50, 60 and 80 mg/L, respectively]. After exposure of 5 and 15 days with each SS concentration, GOT, GPT, glucose, hemoglobin, hematocrit and electrolyte were analyzed. Survival of all species was not significantly affected by each SS concentration. The metabolic rate of S. schlegelii and P. olivaceus increased significantly with an increase in the SS concentration range, but inverse pattern showed in P. trituberculatus and C. japonicas. Blood chemistry of S. schlegelii and P. olivaceus was not significantly affected by SS concentration except hematocrit compared control after exposure of 5 days, but was not significantly affected after exposure of 15 days. These results provide the physiological evidences that suspended solid in seawater provoked significant metabolic and hematological changes of four different marine species.lii and P. olivaceus under eight SS concentrations [0 (control), 10, 20, 30, 40, 50, 60 and 80 mg/L, respectively].
