Raritan river monsters

[shucker]

Decided to hit up the raritan today after dinner and try for some smallies.Water was a tad high and discolored so i started with old faithful a white mister twister on a 1/8 oz jig head.Picked away at average smallies and rock bass then I took the the one last cast before calling it quits.I got a couple cranks on the reel and my rod doubled over the fish bolted up stream a short distance then turned and took me almost to the spool.I ended up running downstream chasing the fish at least a few blocks.Once i got it on land I realized I foul hooked it the dosal fin I'm not sure what kind of fish it was but it was huge at least 25Lbs,It looks like a carp but with a mouth like striper a huge dosal fin and hump back.after talking to andy I think it mite be grass carp I probably should of killed but didnt.
