Ecological roulette is a term occasionally used to describe the human-induced spread of aquatic non-indigenous species (NIS), since all new species introductions do not necessarily cause harm to the recipient environment, but it is impossible to predict which species will be harmful – and where, and when. This roulette is still very much alive, as a relatively new study on NIS introductions to Finnish marine waters indicates that new species continue to arrive through anthropogenic means.
