对2007～2011年间上海港的60艘外来船舶压舱水样品进行了调查和分析。结果表明进入该水域的外来船舶压舱水中赤潮种丰富度较高,共发现62种赤潮生物,分别隶属于5门32属。其中,出现率较高的种有菱形海线藻(Thalassionema nitzschioides)、圆海链藻(Thalassiosira rotula)、长菱形藻(Nitzschialongissima)、中肋骨条藻(Skelrtonema costatum)、丹麦细柱藻(Leptocylindrus danicus)、尖刺拟菱形藻(Pseudo-nitzschia pungens)。初步评估显示外来船舶压舱水的排放对上海港生态具有一定风险。
The ballast water samples of 60 foreign vessels in Shanghai Port from 2007 to 2011 were investigated and analyzed. The results showed that there were 62 species of red tide organisms found in the ballast water of exotic ships entering the water area, belonging to 5 genera and 32 genera respectively. Among them, Thalassionema nitzschioides, Thalassiosira rotula, Nitzschialongissima, Skelrtonema costatum, Leptocylindrus danicus ), Pseudo-nitzschia pungens. Preliminary assessment shows that the discharge of ballast water from a foreign vessel poses a certain risk to the ecological environment of Shanghai Port.
