Stocking Fish
When to Stock
Timing is critical for fish stocking success. In Arizona's warm climate, the best stocking windows are spring (March–May) and fall (September–November), when water temperatures are moderate and fish experience less transport stress. Summer stocking is possible but requires extra precautions for oxygen maintenance and temperature control.
Rainbow Trout are stocked exclusively in cooler months (November–March) when water temperatures are below 65°F. Tilapia and other warm-water species thrive with summer stocking.
Recommended Stocking Ratios
For a new lake focused on recreational fishing, a typical starting ratio is:
| Species | Typical Rate (per acre) | Role |
|---|---|---|
| Bluegill | 500–1,000 | Primary forage base |
| Largemouth Bass | 50–100 | Top predator / sport |
| Channel Catfish | 50–100 | Bottom feeder / sport |
| Fathead Minnow | 1,000–2,000 | Initial forage (Year 1) |
| Redear Sunfish | 50–100 | Snail control / sport |
Rates vary based on water depth, existing vegetation, management goals, and water quality. Contact us for a customized stocking plan.
What to Expect After Stocking
Fish need time to acclimate. In the first 2–4 weeks after stocking, fish will establish territories and adapt to the new environment. Mortality of a small percentage (typically 2–5%) is normal and should be expected — especially during warmer months.
In a properly established lake with adequate forage, Largemouth Bass will reach catchable size (10–12 inches) within 18–24 months. Bluegill will begin spawning in the first season, building your forage base naturally.
Supplemental feeding can accelerate growth rates significantly — see our Supplemental Feeding page for details.
