I am not nearly as qualified as many others on this forum to address questions about largemouth bass but I can talk quite a bit about Striped Bass Hybrids. If you check with your local weather service or on the internet you can find out what the daily mean temperature in your neck 'o the woods. If it is below 80 degrees F. during late July you could raise trophy size SBH. There's one big problem that you need to think about. Big largemouth can be grown in a small ponds without large amounts of supplemental feeding. This, however, is not true of SBH. You're gonna need to feed and feed and feed and feed. You could end up with lots of nice fish, but you could end up with significant water quality issues. It would also be important to establish how much "flow through" you have in your pond. If the water is replaced quickly and frequently by either runoff or well water then maybe th SBH could be utilized. Have you considered largemouth management with maybe 10 or 15 SBH? Lots of options but lots of potential fun and enjoyment in your life!
