When bluefin tuna season ends in Gloucester, Mass., it's just beginning in North Carolina's Outer Banks, a perfect opportunity to pit North vs. South in a pro fisherman contest for the ocean's most lucrative prey. Venturing south are the best crews from Gloucester to take on top local fleets in the treacherous Outer Banks, where the weather is more unpredictable than up north, and the seas can be extremely rough. The Gloucester rod-and-reel vets must master "greensticking" -- trolling artificial squid from a 30-foot fiberglass pole to lure the elusive species to the surface. Top-dollar bluefin can be worth as much as $20,000 each, but a short season and small government catch quota means explosive rivalries surface quickly.

Before complaining about the market price of Alaska king crab, check out this gripping documentary series, revealing the mortal perils and intense discomfort that fishing crews face on the Bering Sea to catch the delicacy.

Ten of the world's top anglers compete in a series of unusual fishing challenges.

Each year adventurers make Alaska's mighty Yukon River their home for five weeks. They float downstream on homemade log rafts to sell firewood and other supplies to remote villages. The reality-documentary "Yukon River Run" presents hourlong episodes tracking the progress of various crews. As harsh winter months approach and threaten both safety and success, stakes are heightened as rafters endeavor to cash out and escape from the cold.

With laid-back indie film director Michael de Avila at the helm, "Lunkerville" is not the typical hard core, host-is-the-star fishing show. It's quite the opposite, actually. Its foundation is the marriage de Avila -- as its creator and host -- creates between two of his passions: storytelling and bass fishing. He travels the country looking to hook everyday, recreational bass fishermen into sharing their secret casting spots, special techniques and love for the sport. Mike D, as de Avila is known on the series, isn't the star; the amateur anglers are -- the real people with real fish stories.

The old Dolly Parton hit "9 to 5" isn't a tune worth humming for the blue-collar pioneers featured in "Filthy Riches." The series spotlights ingenious Americans who skirt a conventional workplace in favor of making a living in the deep rivers, soggy mud flats and wild backwoods of the U.S. Ray Turner, for example, has been catching eels in Delaware for 30 years. He uses a self-made smokehouse in the woods to cook the critters and sell them. Billy Taylor and his sons hunt for prized ginseng root in the Appalachians. Taylor, a fully licensed wild ginseng dealer, promotes sustainability by planting its berries. In Maine, Jim Campbell and Andy Johns make the coastal mud flats their office, as they dig for valuable bloodworms to sell to fishermen. And Greg Dahl and Albert DeSilva are burl hunters. A burl is a hard, unwieldy outgrowth on a tree, usually at the trunk. Burls have value because of the spectacular patterns found in them when cut open.

Best friends Chris Owens, Brian Jill, Thad Robison and Jay Johnson go where no one has ventured before to fuel their passion for extreme fishing. To chase rumors of giant fish in untouched waters, the adventurers explore Earth's most remote, dangerous destinations, from glacial streams in Greenland to raging rapids in Borneo. The largely self-shot series allows viewers to trek alongside the foursome on their journeys, during which they meet and befriend locals, and trail some of the most remarkable, elusive fish in the world. In the end, the guys are bonded by one idea -- the only difference between an obstacle and an adventure is one's attitude.
