The Lionfish (Pterois volitans) is a rapidly spreading invasive species, and has arrived to sites near Cancun. We must keep this fish from establishing here! It is a voracious eater and will displace native species, and disrupt the fragile balance of the reef ecosystems. Also, it is poisonous!
What can you do to help? If you are in Cancun, you can help by keeping a lookout for this fish, and reporting sightings to the cancun national parks office or to me via this website (leave me a comment or send me an e-mail). In fact, tonight the parks office is presenting to tour guides about the fish and to bring them into the monitoring effort.
You can also help by discouraging people from selling invasive species outside of their native range, and most of all – DO NOT RELEASE PETS INTO THE ENVIRONMENT. The lionfish was introduced into non-native environments by people releasing their pet fish into the water. You may think you are setting your pet ‘free’ but in reality, you are setting up a massacre, of native species that get displaced, and of the offspring of your invasive fish as we try to eradicate it from the area to restore the ecosystem.
