| Abstract |
The serpulid tube worm Hydroides ezoensis, originating from the Pacific and introduced near the mouth of the Loire River, France in 1973 or earlier, did not spread widely. After it had been recorded in southern England in 1976 and northwest France in 1997 no newly colonised areas in Europe were reported. In the course of monitoring of hard substrata in North Sea ports in the Netherlands we found H. ezoensis at two locations, about 40 kilometres apart, Rotterdam and Vlissingen (Flushing), more than 40 years after its last significant range extension. We hypothesise that rising water temperatures during the last decades may have contributed to this northward spread. Although the number of worms we collected is very low, this first colonisation in the North Sea area enhances the chance of spread along its borders. |
