I'm still a young teen but I want to have a good idea in what career I might pursue. I want it to involve fishing too any ideas?

Look into fisheries management as a freshwater biologist, with guiding as a possible side business until/if guiding starts bringing in enough income to be a full time guide.

Get an education, or a good trade first.  Then pursue your dreams and see where the chips may fall.  You will always have something to fall back on, if your dreams don't pan out.  

I'd say it depends what you want to do. Do you want to actually be out on the water fishing? Or do you just want to be involved in the industry somehow? If the second one is fine then there are probably a good amount of design/manufacturing opportunities with lure/reel/rod companies.

I agree with geo, get an education. Possibly even in biology or something similar where you can work closely with wildlife. You could try for wild life management and possibly be a warden. There's plenty of opportunities but don't decide not to further your education just because you want to fish. Even if it is an education on something as a back up plan like geo said. 

Look into a college that offers degrees in conservation .

Unity college in Maine graduates lots of wardens, marine and wildlife biologists etc.
