Invasive marine species are not an easy problem to deal with, although fortunately, as the oceans are naturally interconnected, it is not very often a problem that is encountered. When it does occur however, it can be as much as a problem as it is in the terrestrial environment, as with the recent invasion of the Lionfish throughout the Caribbean region. We offer a full assessment service, together with the development and implementation of a response plan to best mitigate the situation. Using the Lionfish as an example, it is understandably not possible to ever entirely eradicate the species once it has successfully established. With drifting larva and broad habitat preferences it is just not realistically possible. However, public awareness and other outreach materials are key to avoiding unnecessary human encounters with their toxic spines. It is also possible to encourage fishers to target the species as a delicious tropical treat, and also remove this dangerous stinging species from popular shallow swimming areas by way of speargun. By undertaking these activities, it is hoped that it will give the natural environment time to adapt to this new inhabitant, and hopefully find a balance that is beneficial to all.
