FYI....Bob L. did a lake survey for us about 9 years ago now, and suggested we add threadfin shad. We put in around 5000 and I believe the month was April. The size of the fish we were catching improved dramatically within a year or so. We have had to run off the water turkeys but the shad have survived very nicely. I would certainly recommend your stocking them. Our lake is about 20 acres, with not a great deal of cover. The avg. depth is about 8' ranging from shoreline to 18 or 19 ft. Best of luck to you
