2000年4月，人们在克莱德海观察到大量的半balanus balanoides藤壶。在一个地点记录了该物种的700个塞浦路斯人1−1。这比以前记录的数量多了3500倍，导致一些塞浦路斯人在浮游生物中发生蜕变，以及大量定居，在成人和飞溅区发现了新成员。记录的最大密度为109个定居者cm−2。在接下来的60天里，死亡率平均为85%，2000年6月新兵的平均密度为8.4厘米−2。在km和m尺度（地点、岸线高度）上，种群的招募存在空间差异，但没有证据表明其受同种成虫存在的影响。
In April 2000 a massive recruitment of the barnacle Semibalanus balanoides was observed in the Clyde Sea. At one location 700 cyprids 1−1 of this species were recorded. This is ∼3500 times more abundant than previously recorded, and resulted in metamorphosis of some cyprids whilst still in the plankton, as well as massive settlement, with recruits found on adults and in the splash zone. The maximum density recorded was 109 settlers cm−2. Over the next 60 d mortality averaged 85%, resulting in a mean density of 8.4 recruits cm−2 in June 2000. Recruitment varied spatially at the km and m scale (site, shore height) but there was no evidence that it was affected by the presence of adult conspecifics.
