Lurking in the murky depths of the world’s great waterways are bizarre giants — specimens of such enormous proportions and odd appearance they boggle the mind. Remarkable freshwater fish that can reach astonishing lengths of 3.5 metres, weigh a scale-busting 200 kilograms and carry heavy suits of scaly armour. Some breathe air and are even rumoured to prey on people! Other aquatic giants have survived since the dinosaurs but now are dwindling in numbers and face an all-too-real threat of extinction.

Fish Warrior features lifelong adventure angler and world record-holding fisherman Jakub Vágner as he embarks on extreme fishing expeditions to the most remote regions of the world. Deep in the South American jungle, Vágner searches for a true “dinosaur of the deep” — the arapaima, which can weigh 180 kilograms and roams the Amazon River system/basin. And on Kenya’s Lake Turkana, he tracks a 1.8-metre-long perch — a valuable source of food for the region. Along the way, he meets the locals, observes their customs and hears surprising fishing legends.


  • Fish Warrior: Amazon Giant
    Vágner treks deep into the Amazon in search of a river monster essentially unchanged since the Jurassic age — the arapaima. These skilled predators can grow to massive proportions and can eat just about anything; they can even snatch up birds and monkeys from the water’s surface! It’s a gruelling expedition, but after days of hiking, canoeing and camping in the jungle’s extreme environment, Vágner makes the catch of a lifetime. He reels in the biggest arapaima he’s ever seen, a 3-metre-long specimen, measuring nearly 1.5 metres in girth and weighing a whopping 147 kilograms!
  • Fish Warrior: Colossal Catfish
    Vágner ventures into the world’s largest rain forest to go head-to-head with the giant piraiba catfish. These megafish are some of the largest catfish on earth, with record breakers stretching more than 3.5 metres long and weighing a scale-busting 200 kilograms. They use whisker-like appendages to search for food, and though mainly preying on other fish, have been known to eat birds and even monkeys. Local legend even tells of these powerful predators dragging fishermen to the river’s bottom! Vágner endures torrential rain and sleep deprivation to catch this mega catfish of the Amazon.
  • Fish Warrior: Nile Mammoth
    Vágner travels by any means necessary in search of the Nile perch in Lake Turkana, Kenya. This megafish can grow to about 1.8metres, 200 kilograms, and could be a popular export for the country, except for concerns about a potential parasite that may make the perch dangerous to eat. Vágner is called in to catch a large specimen of the freshwater beast for scientists to examine and determine if there is in fact a deadly parasite problem. But extreme heat, wind and sandstorms make the journey treacherous and have Vágner struggling to push on.
  • Fish Warrior: Texas Titan
    Deep in the murky waters of Trinity River in the U.S., Jakub searches for a true “Texas titan,” the alligator gar. The gar are known for their bony skulls, armour-like scales and piercing teeth, but their natural weapons cannot protect them from overfishing and environmental changes. Jakub’s mission is to help scientists tag several fish for data and seek out a huge gar to catch and release, hoping to prove that big specimens are still out there. Catch the excitement of Jakub straining to land a true behemoth — a 57-kilogram, 1.8 metre gar!
  • Fish Warrior: Living Dinosaur
    In British Columbia, Jakub Vágner goes head-to-head with a fish he has never faced before — the white sturgeon. This prehistoric fish is like no other. With a skeleton of cartilage and rows of sharp plates called scutes around its body, white sturgeon are able to grow to more than 680 kilograms. However, this remarkable species has suffered a decline in population because of habitat destruction and overfishing. Jakub joins local experts on a mission to catch and tag white sturgeon to aid the species’ survival.
