Are those Macrobrachium? The freshwater river prawn? I can't find anything on the site, but I doubt they're doing the world's largest saltwater aquarium...
Unless the grow multiple species, it's pacific white shrimp [1] which seems to be a salt water species. Also the pictures do not look like Marcobrachium
Wonder if that means they're just using stock photos of shrimp. The other guy wasn't lying when he said "interior", it's about as far from the sea in Spain as seems possible. I thought all the non-coastal fish-farming ops were doing freshwater species.
