In recent decades, gobies have dispersed or introduced from the Ponto-Caspian region of eastern Europe in a westerly direction to North American and western European waters. By contrast, the naked goby, Gobiosoma bosc, is the only known gobiid species to have been introduced in an easterly direction from North American to western Europe. The potential invasiveness of G. bosc was assessed using the Aquatic Species Invasiveness Screening Kit (AS-ISK) for rivers and transitional waters for the western and eastern sides of the North Sea. Using globally-derived thresholds, G. bosc was assessed as low-medium invasiveness risk for both sides of the North Sea under current climate conditions. Under future climate conditions, potential invasiveness will increase for both risk assessment areas. Environmental suitability assessment indicated an increase in environmental suitability for G. bosc on the eastern coastline of the North Sea under climate change scenarios and suitability remained unchanged on the western coastline, reflecting the authors' expectations of invasiveness risk.

近几十年来，虾虎鱼已经从东欧的蓬托-里海地区向西向北美和西欧水域扩散或引入。相比之下，裸虾虎鱼Gobiosoma bosc是唯一已知的从北美向东引入西欧的虾虎鱼物种。使用水生物种入侵性筛选套件 (AS-ISK) 评估北海西部和东部的河流和过渡水域的G. bosc的潜在入侵性。使用全局派生阈值，G. bosc在当前气候条件下，北海两岸被评估为中低入侵风险。在未来的气候条件下，这两个风险评估领域的潜在入侵性都会增加。环境适宜性评估表明，在气候变化情景下，北海东海岸的G. bosc的环境适宜性有所增加，而西海岸的适宜性保持不变，反映了作者对入侵风险的预期。
