Tips For Live Release Tournaments
- Use a big enough live well; one pound fish per gallon of water.
- Use a minimum 750 gal/hour pump.
- Use ice and water exchanges, and keep the live well water temperatures 5–7 degrees F below the river water temperature.
- Take extra care when fishing summer tournaments. Extreme heat can be a killer.
- Use continuous circulation and frequent water exchanges, and periodically lift the lids of live wells to expel carbon dioxide. This may require more of your attention during periods of rough water when bass experience increased stress.
- Act quickly if the live well stops working! Bucket in fresh water every 10 minutes, use a spare pump, move your fish to a working live well, or release them.
- Use an effective culling strategy that prevents tearing the lips or tissue of bass.
- Remove dead bass from live wells; do not discard harvested species at boat ramps or near parking lots. In many cases, harvested fish can be consumed or donated for consumption.
- Clean and remove algae or plant material from live well and intake systems.
