I have caught many 20+ lbs bluefish (I used to fish in Long Island)
I caught a 42" Striped Bass
I caught a catfish in Uruguay that was at least 50+lbs. when I was a kid.
I caught a grouper in Key Largo that was at least 100Lbs. What an ugly fish.
The best tasting fish I have ever had was flounder caught in Lon Island Sound.
