This last weekend, me and JetDoc and my son went down to the Ohio River near Derby Indiana. We have been there before and caught lots of nice fish, but this past weekend, we caught 2 small channels and 1 buffalo. That was it for 3 days of fishing. The thing is: The last time we were there, I saw no commercial nets, but this time we saw at least 15 in a 2 mile stretch and we saw the people working them. We drifted and anchored both deep and shallow and could not buy a bite. Had fresh shad and skippies too. Ive seen some other reports from the river where people caught fish at other locations, so I ask...Can commercial fishing on such a big river really make that much of a difference? I say yes based on our results, but I want to hear what everyone else says.
