Aquaculture plays an essential role in the French maritime economy, with shellfish farming representing one of its most active sectors. Although indispensable for both food supply and the economic vitality of coastal areas, the industry faces several challenges that hinder its development. Among these, predation remains one of the most concerning: an ancient but increasingly pronounced phenomenon that affects a large number of farms and endangers their financial stability.

In a context where production shows contrasting trends, it is crucial to assess the effects of these natural pressures to ensure the sustainability of shellfish farming in France.
