Veta la Palma in southern Spain is a commercial fish farm with a difference. The 113 square kilometre estate has a network of shallow ponds and marshlands that hosts 250 different species of birds, naturally occurring algae and shrimp, and of course, fish. Unlike intensive fish farming, Veta la Palma has a positive environmental impact. But it still does good business, selling its high quality fish to restaurants around Europe.
