EVOC: Economic valorisation of invasive crayfish
Résumé
Invasive species cause severe problems for native fauna and flora and significantly alter natural ecosystems, through competition or predation. Invasive species may also be vectors of diseases to which they are immune, but that play a negative impact in native species (Correia 1993). The red swamp crayfish (Procambarus clarkia) native from the USA has been introduced in Spain in the ’70s but has spread throughout the Iberian Peninsula watersheds. The vicinities of the river Vouga, ecosystems provide the ideal conditions for these invasive species to thrive, occupying niches and slowly destroying and replacing the existent native species. Crayfish high resilience even in the most adverse conditions makes difficult their eradication from the areas already occupied by them. In fact, like many other invasive species, their control can only be made by i) employing high financial resources to control the populations for a period of 1 to 2 years or ii) using the species as an economic resource that can be easily controlled by local populations.

The EVOC project is a Citizen Science approach for Estarreja population providing the necessary tools for monitoring and controlling the population of crayfish in the region and additionally providing them with an economic resource for the future. This will be possible by monitoring water lines for this species, analysing them for their nutritional content and proving information regarding its culinary use and preparation.

EVOC is expected to provide researchers with biological information regarding this species and to increase environmental awareness and even provide an additional source of food supply or economic resource to the populations.
