Expansion in the Mediterranean
The arrival and establishment of a species from another region of the world can alter the ecology of local communities. In the Mediterranean, an important entry route for tropical fish is the Suez Canal. In 2000, the species Fistularia comersonii was found for the first time and it has now reached the Iberian coastline.
Within the framework of several international projects, data are being gathered concerning the presence of exotic fish in the Mediterranean for long-term monitoring of their impact. However, detecting new species at the start of colonisation requires us to be in the right place at the right time.
How to get involved
If you dive or fish, you can detect the arrival and expansion of exotic species and contribute to their monitoring. Take photos of fish you do not recognise or any invasive species described, and report their abundance, location and other simple but relevant aspects.
