Bob, you're giving me the opportunity to express a concern I have... :-))
It is bad practice to move any species of fish as adults in pre-spawn mode..
I can't even guess how many calls I've had already this last month wanting to know if I can load up females and get them in a pond so they will spawn this year..
By doing this it is more likely that they will reabsorb eggs as opposed to completing a spawn. Pre-spawn is VERY focal for all species and is a terrible time to move them. period.
Not sure why this bothers me so, but it does.. I see a trend towards larger stockers, and I think that's a mistake in most situations where it's involving a new pond.. Existing pond, yes, I can see using larger sizes but it needs to be done at the "Least" stressful time of year for the "highest" survival.
Sorrry for the rant, I just see some things changing on thought process that I think still need to be held to a standard.
