An exhausting battle with a colossal white sturgeon pushes Cyril to the limit, but before the team can tag the eight-foot giant, it gives them a giant-sized shock. A freak wind storm then forces the team to put their white sturgeon quest on hold and head far north into the mountains to help protect the sturgeon's main food source: the pacific salmon. In order to find these migrating warrior fish, that can weigh up to 100 pounds, the guys will have to leave civilization behind and survive in one of the most hostile, rugged mountain environments in the world. Out here, hostile terrain, black bears and grizzly bears lurk around every corner. This is from Wild Fish.

Growing to over 12 feet long and 1300 pounds, the prehistoric white sturgeon is a true freshwater giant, but because of human activity, its populations are now in decline. Cyril and his crew embark on a dangerous, action-packed mission to help scientists protect them. But to find this massive animal, the team must search the raging mountain rivers and dive beneath their frigid waters, all while avoiding bears, rock slides, freezing temperatures and deadly currents. This is from Wild Fish.

Their guides abandon the crew in a hostile area and they must now trek on foot into uncharted territory that exposes them to true danger when they cross stingray-infested rapids, run into an ominous poachers camp and face down armed, angry hunters. Their scientific research is at stake, and the guys are forced deeper into the jungle than ever before to find the 200-pound giant piraiba they need to sample. But with a colossal fish finally on his line, Cyril is in for the fight of his life when he gets dragged into a river full of giant black piranhas. This is from Wild Fish.

It's a battle for survival when a massive piraiba pulls the team down a raging river before they can sample it. Potential disaster greets them at every turn, and the guys are forced to change strategies. Merciless rapids, hidden stingrays, motor failures, lightning strikes, black piranhas and massive falling trees are just some of the dangers the crew must overcome in their quest to sample a giant piraiba for their research. And with a mysterious fish on his line, Cyril gets much more than he bargained for, in a truly dangerous battle. This is from Wild Fish.
