Ponds in research park have some quality fish in them. There are signs that say no fishing, but I never got in trouble for fishing it. I was told the pond at the police station is fantastic, but I never fished it. The pond at Gabbard Park has some fish in it. I lived over there but never caught any big fish from it.
Join the Aggie Anglers. It is the A&M bass fishing club. You don't have to have a boat to join, and will get the opportunity to fish some tournaments out of the back of other student's boats. Aggie Anglers Facebook
