Interesting topic. I have to think they stay close to where they are released.

I am a member of a semi-private lake (about 65 acres). Over the course of about 6 years, me and my buddy caught, measured, weighed, tagged and released over 150 bass between 12" and 8 pounds. Several of those fish were caught and released again through the years. This is what we found... Their growth rate was about a half pound per year. Also, the fish we caught again were always in the same general area. For example, they would be caught 2 years later, 100 feet down the same bank.
