Integrated Biomarker Responses of a Brackish Water Clam to Global Warming Conditions

To analyze physiological and biochemical marker responses of brackish water clam Corbicula japonica under global warming conditions, different temperatures (20°C 25°C), salinity (5 20 psu), food availability (0.5 2.0 mg SS ind−1 d−1) levels were tested. Appropriate biomarkers selected based on the sensitivity biomarker responses, condition index (CI), energy reserves, superoxide dismutase (SOD), catalase, oxyradical-absorbance capacity, lipid peroxidation (LPO) (p < 0.05), five methods integrated response (IBR) calculated. CI, SOD, LPO employed for IBRI, although four generally IBR. At high temperature (HT), all deleteriously affected. HT significantly affected IBR highest correlation was discovered in IBRI (r = 0.92, p 0.01). The lowest IBRs observed at natural (control 1.14) (HT 2.43) respectively. contribution scores higher HT, demonstrating poor organism health. Based our estimates, three sensitive could detect stress C. conditions. We conclude that method should be used to quantify anthropogenic impacts aquatic organisms, especially japonica.
