Congrats on your first nook! It doesn't really matter how big it was or how bright it was for the catching anyway. At least you got to feel that tug and you got some confidence that your bait and gear work well.
However, now you are ruined. You should seriously consider quitting your job or school and focus 100% on catching more salmon, J/K...
Anyway, it makes sense to release the buck to go make more as it is a bit colored up for eating. Karma would suggest that you get a good chromer next time out.
Best,
