I'm thinking that they have high aspirations for you and ones that, it sounds like, you can easily live up to. They see fishing as a distraction to your future studies, and they are right! College is tough, and not really the time in your life that you should be seriously fishing.
Maybe you could find a cheap float tube, just to get you off the shore. Something you could easily sell before college. The next couple years will pass quickly, so don't dwell on this too much.
