From the rough waters of the Nile River to the seas surrounding the Seychelles islands in the Indian Ocean, South African naturalist and extreme fisherman Andy Coetzee is embarking on a journey to reel in some of the world's biggest fish - the most elusive, notorious and at times, the strangest creatures in the water. In many of the planet's wildest places, Andy comes face-to-face with the giant swallowing mouths of the Nile perch, the heavyweight power of the Dogtooth Tuna and the razor-sharp teeth of Giant Barracuda. FISHING FOR GIANTS premieres Wednesday, April 25 at 8 p.m. ET/PT on Smithsonian Channel. Never settling for an average day on the water, Andy goes to great lengths to make the most dangerous catches. His all-action fishing style doesn't rely on expensive tackle or hi-tech gadgets. Instead, on FISHING FOR GIANTS, Andy depends on his expert skill and hard work - whether it's free-diving submerged wreckage to face a catch head on, staying calm in crocodile-infested waters on the Nile, or using an old-school wooden-spooled reel, the Scarborough which he calls his 'old-faithful' to bring in these 100-plus-pound giants.
