Thanks Andrew and Vogey for the replies.
Andrew: I do not eat Rios but have been told that they are great table fare. Steve is a "Master Cook" when it comes to fish. He can fry em,grill em,broil em,and even makes a great gumbo. He also smokes em.
Steve says the Rio meat is white very similar to the sunfish. He says Rio's are great fried and grilled.
My top three fish to eat are #1. White Bass,#2 Crappie and #3 Bluegill/Sunfish! I also love catfish and trout!
Vogey: We fished Dunlap right at day break and caught about 12 Channel Catfish all in the 2 to 4 pound range. I had one break off that would have easily gone over 7 Lbs. Should have netted it.
The weed beds were on a creek. As for the Rios,Steve will eat em small,medium,or large!
