Treacherous Alaskan Salmon Fishing show last night

[Swimmer]

Watched a show last night on National Geographic (thank you Moses) after the monster fish show was over about salmon fishing at the mouth of the river/inlet where all of these aluminium boats smack into each other while trying to gil net salmon. It looked like it could get very heated. There were numerous state troopers in the area to keep the boats from fishing to far up into the inlet and to separate certain mad as hell boat captains. Did anyone else watch this show?
