only when young native fishes are scarce or absent, but lack of reproduction is seldom the cause of poor angling success. Neither state nor federal hatch eries normally stock catchable size pond fish species. Adding more fish to waters already over-populated with under-sized bass and bluegill can increase competition and suppress growth even more. Overharvest of adult bass is one of the prime causes of poor fishing, especially in smaller ponds subjected to heavy fishing pressure’. With no large bass to reduce their numbers, the prolific bluegill will multiply until there are too many for the available food. A 12 or 14 inch minimum size limit on bass is the most effective tool discovered to date for combatting this situation. Draining or poisoning the pond and then restocking
with proper numbers j of fish can, in many cases, speed up the recovery process.
Another problem that can cause poor fishing is excessive competition from trash fish. Treatment with selective chemicals can eliminate these without harming game fishes and restocking is seldom required. Weeds can provide too much cover for forage fishes like bluegills and allow them to over populate as well as mechanically interfering with angling. Chemical treatment is effective in small ponds.
