I'll bite. I have a hard time keeping a creek chub alive on a hook for more than a short length of time. Given that, and the fact that they don't do well in a non stream setting, I'd think they would be a somewhat benign species to introduce into your pond, and wouldn't have a long shelf life.

But then again, I'm having problems finding larger bg for my filling pond, and have transferred approximately 130 mature bg and res from various ponds around me, these were introduced into a stocked population of 3" to 5" bg and res. I know that goes against conventional wisdom of not intorducing species from other bodies of water into your pond... Has anyone on this forum personally experienced some type of disease event, in their pond, from transplanting species? Hopefully this is not off topic.
