XLP涂料对合浦珠母贝成活率、生长及附着生物量的影响

研究了XLP防污涂料对合浦珠母贝Pinctada fucata成活率、生长及附着生物量的影响。经XLP防污涂料处理后的贝，其附着生物量明显低于对照组；经防污涂料处理后的养殖网笼具，其附着生物量也明显低于对照组；贝和养殖网笼具同时用XLP防污涂料处理时，防生物附着的效果最好。经XLP防污涂料处理后，处理前期（30～60d）合浦珠母贝养殖成活率与对照组的成活率接近，或者略低于对照组；养殖120d后试验组成活率则高于对照组。使用XLP防污涂料处理后养殖120d，合浦珠母贝的个体大小及体重高于对照组。试验结果表明，使用XLP防污涂料能有效防御污损生物附着，有利于合浦珠母贝的养殖。

Effect of XLP paint on the survival rate and growth of the pearl oyster and biomass of fouling organisms

In order to preventing the fouling organisms in the culture of pearl oyster Pinctada fucata, the effect of XLP paint on the survival rate and growth of the pearl oyster and biomass of fouling organisms in farm was researched in this study. The shell of the pearl oyster coated with XLP paint, the biomass of fouling organisms on the shell was lower than the control. The net cage of the pearl oyster farm caoted with XLP paint, the biomass of fouling organisms on the net cage was also lower than the control. The effect of XLP paint preventing fouling organisms was most effective when both the shell of pearl oyster and net cage were treated by XLP Daint at same time. The survival rate of pearl oyster was close to or lightly lower than the control, during the earlier stage of treatment （30 -60 d）. However, after 120 days, the survival rate was higher than the control. In the meantime, both the size and weight of the pearl oysier were more than the controls after 120 days cultivation. The results suggested that XLP paint was an effective material for preventing the fouling organisms in the culture of pearl oyster, and helpful for pearl oyster cuhure.
