Despite the unrest in South Sudan, Tourette fishing has found northern Sudan to be "inviting, friendly and safe," which helps explain why they've finished a third successful season there. As for what anglers catch in these waters — the photos in this gallery tell the story. All were taken by Tourette Fishing photographer Mark Murray, whose skill with a camera is readily apparent.
