【摘要】 福建省东山县八尺门网箱养殖区发生中肋骨条藻赤潮期间,跟踪监测赤潮消亡过程及消亡后DO的变化,同时采用室内模拟的方法观测.研究江蓠对赤潮消亡后水体DO的影响.结果表明:江蓠可以减缓赤潮消亡后出现的水体缺氧;采用室内模拟的方法可以预测海区赤潮消亡后DO的变化趋势.更多还原

【Abstract】 Investigation of the dissolved oxygen lack after near shore red tide occurence was carried out during period of a Skeletonema costatum red tide occurred in Bachimen caged marine culture area of Dongshan County of Fujian Province.The concentration of dissolved oxygen (DO) during and after the red tide occurrence was monitored for both on scene and indoor mimic water systems.Gracilaria,a kind of large algae,was applied to the red tide water to investigate its influence on DO.The results showed that the algae could decrease the effect of DO lack after red tide happened.The indoor mimic method might be adopted to predict the concentration trends of DO on scene after red tide occurred.更多还原
