Pure Salmon's land-based salmon project planned for Boulogne-sur-Mer in northern France has come under heavy criticism in the weekly French ecological magazine Reporterre.

The report raises questions about animal welfare in the project, in particular critiquing stocking densities in recirculating aquaculture system (RAS) technology tanks, and contrasting the method unfavorably with conventional projects where fish account for a significantly smaller volume of a netpen's density.

The report cites a number of detractors of land-based salmon production and shows a photo of a protest against the project by animal rights group Animal Vendetta.
