English: The APPEAL-MED project is the Mediterranean component of the APPEAL project (Socio-ecosystem approach to the impact of wind farms) and aims to establish a complete initial state in order to allow a BACI (Before After Control Impact) type study once the wind turbines are installed off Leucate (France, 66). The first part of this internship abled us to modify the AVINOTE software, in close collaboration with its creator Jean-Claude Duchêne, so that it could be used to process photos. Once the software was operational, exploratory work was carried out on a single sampling campaign (APPEAL-MED1). Our objective was to understand if a relationship between the burrows number and the diversity existed in the studied area. As trawling was the dominant pressure in this area, the parameters estimated from the classic analysis of benthic macrofauna (infauna) as well as the videos and photos were linked to the bottom abrasion data. No relationships were detected between the number of burrows and the diversity observed, as well as between the abrasion data and the number of burrows. However, and in line with previous studies, we detected a change in structuring species and taxonomic groups depending on the trawling intensity. This change resulted in a decrease in the number of crustaceans and an increase in the number of annelids and molluscs. Such modifications may have been induced by trawling through an overall alteration of the environment, an elimination of non-target species and through the attraction of predators and scavengers.
