K-man,
here's a couple websites to look at. And you can always ask their HR departments if they know of any other places that might be hiring. Unfortunately, due to over-fishing the industry is on the decline, jobs are scarcer and wages are lower. But you can still probably find an adventure!

(I'd avoid these guys, they had a TERRIBLE rep for screwing over their employees in the early 90s, but you can still use them for information)

(these guys bought out my old company, Oceantrawl, and are pretty good folks I think)
The dangers include falling overboard, being hit in the head by a crane/falling gear/whatnot, slipping on fish parts and landing hard on your a$$, or landing on a piece of rebar that goes 12" into uyour chest but somehow doesn't kill you . . . the biggest danger is forgetting that the spinning flesh-rending blades [note knife content] in the factory will cut you up just as easily as a fish. I dealt with many mangled hands and severed fingers.
I worked out there for almost 5 years, several months straight then a couple months off then several more months on, etc. I have stories to last a lifetime! The best image was silently breaking through endless ice in russia, surrounded by nothing but white to the horizon, with sea lions basking in the sun and barking at the boat as it passed. I saw and treated horrible injuries, saved a life, drank unimaginably bad coffee, learned to play poker, made friends and enemies, learned a lot about myself and grew from it, and met the most diverse and fascinating cast of characters you can imagine. Sometimes it sucked beyond belief, and sometimes (like in a storm with 100mph winds and 60-foot waves) saw things that you simply can't experience anywhere else. AND I saved enough $$ to eventually put myself through law school!
That said, we should probably not diverge too much further from knife content, so I'll save my stories & perhaps let you find some of your own . . . . .
