Yes, one male, by mistake from the seller/buyer or from nature herself and your all-female bass pond has changed. Consider your risks from upstream or downstream. Fish will travel from both directions. Also consider nearby ponds. We've seen birds fly from pond to pond with fish.
At the hatchery you would have to purchase all female adult stock, which would probably be more costly and would be limited to the spring season.
The above posts with different ideas are exactly what I wanted to see, because I want my customers to have better results for the long haul. I know people lead very busy lives and don't have the time to do all the things necessary to maintain balance in bass ponds. I'll think more on the options...
As a hatchery owner I would have to charge more to stock a small pond with special species and combinations, which require extra logistics and more effort to acquire. However, I think it would save time and money down the road.
