Tennessee River Fishing

I went to my marina again yesterday and Got a limit of Crappie Had 2 Slabs+,Caught most on Minnows and a small jig with a yellow & white skirt.
The day started out very slow as I fished about 1 hour and didn't get a bite.I was messing around in my minnow bucket and saw a large minnow about 4 inches long so I put him on the small crappie hook and dropped him in well the float didn't have time to settle ,WhaM!! I thought it was a cat fish at first but it was a large Bass!!I placed him in a bucket of river water and kept him for a short while and got to thinking why kill that lone fish as it don't like like I will catch any thing else so I released him.Well in a few minutes I had a nice Crappie on and began to get some action,small blue gills were a problem seems they will bite when nothing else will.
I did get my limit but fished hard all day to get them they just didn't want to bite much at all.
Well that is fishing!!! Good luck on Your Next trip,Bill
