I am not. I have talked with Ryan Dwyer about this on multiple occasions, and while he's certainly interested, I'm not sure what he's up to these days...so I'm not sure what that means for Mccs at the moment.
I have not head anything about additional pairs caught outside of Ryan Dwyer's pairs, and by the way Ryan tells the story, he is the only one with the permits, and was only permitted to take what he took. Now, I could see pairs outside of Ryan's being in institutional holdings under academic / scientific permits we're not aware of, and that would go a long way to helping. And if you know with authority that these are unrelated to Ryan's 5 pairs (which IIRC only 4 spawned), then it would represent a significant genetic influx.
Unfortunately, there is potentially a strong reason to suspect that the parents in question are not wild as claimed, but could well be Ryan's offspring (as the spawning pair at LiveAquaria are). FAO suggestions are that a minimum starting point is 5 in a population, but it has to ramp up quite substantially rather quickly to survive such a drastic genetic bottleneck. I'm not sure what the minimum PAIRS are for long term sustainability of a captive clownfish population (I hope to have that answer figured out by MACNA), but I can tell you that one spawning pair is not enough, period.
Still, even if the parents were not wild, but were F1's from Ryan's, the would a) not be the same pair as the one @ LiveAquaria, and b) no one can say if all the released fish came from one of Ryan's Wild pairs or if they were all comingled, so you don't even know if these F1 pair(s) are siblings or not. If they were all siblings, that would be the worst case scenario...we can only hope they are not.
