Thanks for the info. As for Sand I am just afraid that they will run out of forage eventually. We used to catch a lot of small perch while slip bobber fishing for walleyes. Now most of the perch caught are pretty decent size. One just has to wonder if these last 4 or 5 years of huge numbers of walleyes are starting to run out of food although the fish there do seem healthy, but you can catch them any day of the week pretty much every part of the lake.
