The invasive fish species round goby is spreading at an incredible rate in the Baltic Sea. In his doctoral dissertation, Magnus Thorlacius at Umeå University in Sweden, presents evidence of asocial behaviour, higher risk tolerance and high activity levels in new populations correlating to the spread. Already three to five years, the fish starts to spread in large numbers to surrounding areas leaving a short window for measures to prevent further spread.
