I had gizzard shad and threadfin shad at one time but the threadfin have declined or died due to our hard winters in the last couple of years. If I could learn to throw a cast net I could replenish the pond with threadfin since I am only about five miles from a large reservoir that is full of them. The gizzard shad we removed were very large adults that only a few of my biggest bass could eat. Bob thinks that most of the spawn from this year traveled down stream when my dam broke this spring and I lost this years spawn. I was also surprised that I didn't see any large crappie but we also didn't get any catfish. The boat only reaches about six feet deep.
