Lluis Benejam i Vidal, professional experience

His doctorate was focused on using freshwater fish as indicators of the state of conservation of the aquatic systems of the Mediterranean basin. He has undertaken studies into reservoirs, rivers and marshlands, using different sampling methods: electric fish, gill nets, handles, echo sounder, telemetry... He has studied the effects of pollution on the health of fish and the presence of parasites and malformations. Additionally, during his doctorate he collaborated on different projects in order to study the impact of exotic species, specifically the European catfish (Silurus glanis) and the Eastern mosquitofish (Gambusia holbrooki).

In recent years he has undertaken studies to evaluate the state of conservation of different populations of autochthonous crayfish (Austropotamobius pallipes) and Spanish terrapin (Mauremys leprosa). He has also done studies to assess the impact of the American crayfish (Procambarus clarkii) on Mediterranean ecosystems. For several months he collaborated with Mosquito Control Service of l’Empordà. He is currently collaborating on a regular basis on studies in other disciplines such as the Amphibian Monitoring in Catalonia and the Census of Winter Nesting Birds.
