Their an outfit in seward called Saltwater Safari that chases Salmon Shark. http://www.saltwatersafari.com/ I went with them one time for halibut and on the way out we were watching some videos of their Salmon Shark Hunts. What they do is take a whole Salmon and put a giant arse hook through it and rig it so the salmon spins like a herring. They then put their 65 foot boat in gear and troll this Salmon on the surface. it didn't take long and you could see a shark fin around the Salmon. Finally the Shark grabs on to the Salmon and the guy whom is sitting in the battle positiuon all tied in yells hit it when he thinks the shark has a good hold. The skipper then drops the hammer setting the hook with the boat. It looks like a fun battle and ends with a shotgun blast. Apperantly Salmon shark is really good eating. Probably has something to do with what their diet consists of.
