The team head to British Columbia in search of the elusive Coho Salmon, but standing in their way are dozens of hungry grizzly bears intent on fattening themselves up before winter sets in. The trio must work out a way to catch a Coho without ending up as dinner for the bears.

The guys head to the The Bahamas in search of the invasive Lionfish. They are wreaking havoc on native species. They are highly venomous and live deep in the reefs making them impossible to catch on rod and line. The guys must work out a way to remove as many as they can without being stung.

The team embark on a mission off the coast of Peru, with marine biologist Blowfish aiming to prove that big squid are misunderstood - by donning a scuba tank and chainmail suit to catch a Humboldt Squid by hand.

The team hunts for the Patagonian Toothfish. They want to be the first recreational anglers to take on this delicacy, but they live 2km deep in the freezing southern Atlantic Ocean, so their trusty fishing rods are no use.

The team is in Kenya in search of the Nile Perch. To catch it, the anglers must endure a 500-kilometre, bone-shaking drive to Lake Turkana across some of Kenya's toughest terrain, braving torrential downpours, sandstorms and the desert heat.
