The Discovery Channel's Deadliest Catch brings the real-life perils of Alaska crab fishing right into your living room. Each week, cameras on board the Cornelia Marie, Northwestern, Time Bandit, Wizard and Kodiak capture the hostile environment - think sub-zero temperatures, high winds and turbulent seas - as the brave men go in search of their ultimate catch: the Alaska king crab.

Season six of the TV drama begins on the rocky waters of Alaska's Bering Sea. Tension among crew members is high, as conditions become more dangerous, threatening to destroy a successful season of fishing. And before it is over, tragedy will strike and forever alter the lives of an entire crew.

Alaska crab fishing is one of the deadliest professions in the world. According to the 2006 Bureau of Labour Statistics in the United States, the average death rate works out to about one a week during the crab season.

Despite the hazardous working environment, crab fishing is a highly lucrative business. Although the price of crabs fluctuates, they can fetch anywhere from US$4 to US$5 per half-kilo, equivalent to US$25 to US$40 per crab.

Crab season lasts less than four weeks. Vessels patrol the Bering Sea, hoping to snag any of the prized species of crab: red king crab, blue king crab and golden king crab. The fishermen don't only face treacherous conditions; catching the crabs depends on skill, hard work - and luck. Skippers rely on a combination of intuition and experience to determine a location to set their 320-kilogram traps, called 'pots'.

In other professions, a sonar system is commonly used to detect objects in water. The device emits a sound and 'listens' for a return signal. By measuring the echoes, the system can determine the presence of objects and calculate the distance from the boat.

But for the most part, a sonar device is unable to detect crabs. They lie slightly buried beneath the ocean floor, crawling along the bottom, feeding on leftover bits of fish, as well as plankton and algae. Sonar somehow is unable to pick up their movements.

Vessels are equipped with heavy machinery, nets and long fishing lines. Compounded by frigid temperatures, treacherous waves, wet, rolling surfaces, and limited hours of daylight, crabbing is truly a deadly job. The fate of an entire crew is only one imprudent move away from death.

Making things more difficult is the fact that an injured or dead crab could poison an entire pot. Crabs also spoil easily - unless the water they are kept in is fresh and warm, they may as well be kept out of water. Moreover, only male crabs of a certain size can be kept; the rest are released back into the sea.

Yet, in spite of all these hurdles and dangers, crab fishing remains popular and, as Deadliest Catch proves as it enters its sixth season, exhilarating to watch.

Season six of Deadliest Catch premiers at 11pm tomorrow on Discovery Channel
