Despite a large amount of research into invasive species and their introductions, there have been no studies focused on macroalgal transport in ballast water. To address this, we collected replicate samples of ballast water from 12 ships in two Mediterranean harbours (Naples and Salerno). Filtered samples were kept in culture for a month at Mediterranean mean conditions (18 degrees C, 12:12h LD, 60micromol photons m(-2)s(-1)). Fifteen macroalgal taxa were cultured and differed according to the geographic origin of the ballast water. Most of the cultured algae were widely distributed species (e.g. Ulva spp. and Acinetospora-phase). However, Ulva ohnoi Hiraoka and Shimada, described from Japan, was hitherto unknown in the Mediterranean Sea. We show for the first time that ballast water can be an important vector for the transport of microscopic stages of macroalgae and that this can be a vector for the introduction of alien species.
尽管对入侵物种及其引入进行了大量研究,但尚未有针对压舱水中大型藻类运输的研究。为了解决这一问题,我们从地中海两个港口(那不勒斯和萨勒诺)的12艘船舶上采集了压舱水的重复样本。过滤后的样本在地中海平均条件(18摄氏度、12:12小时光暗周期、60微摩尔光子·米⁻²·秒⁻¹)下培养一个月。培养了15种大型藻类分类群,它们因压舱水的地理来源而异。大多数培养的藻类是广泛分布的物种(如石莼属和无柄孢藻阶段)。然而,源自日本的大野石莼(Ulva ohnoi Hiraoka and Shimada)在地中海此前尚不为人所知。我们首次表明,压舱水可能是大型藻类微观阶段运输的重要载体,并且这可能成为外来物种引入的一个载体。
