If your character is over 2 weeks. Did you fish today before you hit 20? As well as after?
If so, any fish you caught when you were lv19, will count towards the ~10 fish per day for Characters under level 20. Even though you hit 20 that cap is still in place.
Over 20 you can catch 200 per day. Under lv20 each 1 fish counts as 20.
