754 44 THE EFFECTS OF Hg 2+ STRESS ON MAIN DIGEST FACTORS AND IMMUNE FACTORS OF SCYLLA PARAMAMOSAIN LI Wen-Jing 1, 2, CHEN Qiang 1, 2, YANG Huan 1, LI Zhong-Bao 1, 2, CHEN Tai-Rong 1, WU Chuan-Qi 1 (1. Fishery School of Jimei University, Xiamen, 361021; 2. Fujian Provincial Key Laboratory of Marine Fishery Resources and Eco-environment, Xiamen, 361021) Abstract An experimental ecology method was conducted to investigate the main digest factors and immune factors activities of Scylla paramamosain exposed to different concentrations of water-borne Hg 2+ (0.005, 0.01, 0.02, 0.04, 0.08mg/L) from 1d to 9d with the natural seawater (salinity 16±1, ph 7.5±0.3) as control. The results showed that the activities of AMS in stomach increased rapidly but the activation effect declined with the extending of the experiment, and inhibitory effect was observed at the late period of the experiment (9d). The Pepsin activities in stomach were increased and positive correlated with the experimental period and Hg 2+ stress intensity, but the Pepsin activities in high Hg 2+ stress intensity (0.04, 0.08mg/L) groups declined near to the control group at the end of the experiment. The LPS activities in the stomach were declined by Hg 2+ stress and the effective enhanced with the experimental period. The results of immune factors analysis showed that the activities of AKP in hepatopancreas were increased rapidly, and lower Hg 2+ stress intensity groups (0.005, 0.01, 0.02mg/L) had the most significant improvement of AKP activities, the AKP activities in higher Hg 2+ stress intensity groups (0.04, 0.08mg/L) increased at first and declined at the end. The activities of ACP in hepatopancreas were increased by Hg 2+ stress, and the time effect and dosage effect is conspicuous. The activities of SOD increased immediately (1d) in Hg 2+ stress and increased gradually during the whole experiment. The activities of LZM were increased and the time effect and dosage effect was visible. Nevertheless, the activities of PO declined by Hg 2+ stress, and gradually reduced during the experiment, but there was no significant correlation between the PO activities and the Hg 2+ stress intensity. In summary, Hg 2+ stress affected the activities of digest factors and immune factors of S. paramamosain, the activities of Pepsin, AMS, AKP, ACP, SOD and LZM were generally increased, while the activities of LPS and PO were declined.
