If there is a puddle in New Jersey, there are likely bluegill in it. They are one of my favorite species to catch, and I keep specimens that exhibit unusual characteristics or scale patterns.
Some Of My Bluegill
“Blue Harry” a typical female bluegill (my son named her). 
“Blondie” a hypomelanistic bluegill (a “blonde” 🙂 ). 
This specimen has no name, but appears to be a chimera with two different tones.
