How can I block out the smells from my seafood clerk job?

I dont know if nose plugs can do the trick or ?? I just got a job in one and just the smell makes me wanna quit even if I have great hours and pay...No im not gonna change jobs..no i dont wanna just get used to it (they picked the job for me) and i cant just leave every once in a while when the stench gets real bad..thanks!
