【摘要】 为了更好地了解舟山海域环境状况及浮游生物的多样性,本研究分别于2018和2019年春季在舟山摘箬山岛附近海域进行两次生态调查。结果表明:调查海域2018年春季温度和溶解氧显著高于2019年同时期水平,而盐度在2018年显著较低;在这部分海域监测发现:主要的浮游植物以硅藻为主,浮游动物以桡足类为主,这与舟山海域浮游生物历史资料相符;同时,监测还发现有大量夜光藻出现,这是后期舟山海域出现"荧光海"的主要生物种,夜光藻的大量出现,也为当地海域网箱养殖带来一定的危害。更多还原

【Abstract】 To better understand the environmental condition and plankton diversity in Zhoushan offshore area,a two-year investigation program,Spring of 2018 and 2019,was conducted.The results showed that( 1) temperature and dissolved oxygen( DO) in the spring of2018 were significantly higher than that in 2019,in contract,salinity was significantly low in 2018.( 2) Diatom and copepod are the dominant phyto-and zooplankton,which is consistent with the historical investigation in Zhoushan offshore area.( 3) A large number of Noctiluca scintillans,the causative species of the"fluorescent ocean"of Zhoushan offshore area.Bloom of Noctiluca scintillans may cause serious damage to the cage aquaculture in the local area.更多还原
