Economic impact study of the lionfish invasion in the Caribbean
Context
The lionfish invasion in the Caribbean
The lionfish invasion is considered one of the most problematic invasions in the world in terms of conservation.
Through the gradual colonization of all coastal waters of the Caribbean, lionfish impact the economic sectors of fishing and tourism, threaten human health, and potentially harm the services provided to humans by coral reef ecosystems, mangroves, and seagrasses by destabilizing the food chain of these species already under significant pressure.

Assessing economic costs and analyzing control strategies
As part of the PoLiPA project (Lionfish in the Lesser Antilles) led by the Observatory of the Marine Environment of Martinique (OMMM), Vertigo Lab conducted a study aimed primarily at assessing the economic costs of the lionfish invasion in the French Caribbean.
It also resulted in a cost-benefit analysis of the control strategies considered to curb this invasion.
BENEFITS
Demonstrating the economic interest in combating lionfish
This study has allowed for the quantification of the costs generated by the lionfish invasion in the French Caribbean: the total cost generated by the invasion amounts to over 10 million euros per year.
The economic assessment over 5 years of the considered strategies attests to the economic interest in promoting action against lionfish, as they would generate around 5 million euros in net benefits, an amount greater than the net benefits produced in the case of inaction.
