Stocking a Natural 30-ft Pond for Bug Control

Bluegill/sunfish: Excellent insect/larvae control, coexist with bass.
Fathead minnows: Mosquito larvae specialists, forage for predators.
Catfish (channel): Bottom scavengers, eat leeches.
Tilapia: Algae/insect control, but die <55°F (seasonal only).
Golden shiners: Mosquito control, bass forage.

Natural pond ~30 ft diameter, 15 ft deep. Wants fish to control bugs/leeches. Has large bullfrogs.

Fish Suggestions

Bass + bluegill + catfish = balanced sport fishery.
Koi/goldfish = bass food, not bug control.
Bullfrogs eat small fish, add waste. Need robust filtration if keeping many fish.
Leeches: some fish eat them, but not reliable control.

Choose based on goals: fishing, bug control, or aesthetics. Research species compatibility for your climate.
