I have thought seriously about adding Hybrid striped bass that I absolutely love to catch and release. They will not reproduce and will grow in the 12- 20 pound range. Just 5 or 6 in my 3 acre pond that is heavily covered with cover. My pond is still filling and stocked with small bass, bluegills, and fathead minnows, so maybe in 2 or 3 years I will try this.
