Is there any record or anecdotal evidence of a released alterna being recaptured at a later date?
It would be interesting to know the distance traveled, weight change and growth rate between captures.
Perhaps some sort of protocol should be established for records on all released animals (Obviously only at the time and place of capture, NOT reintroduced captives to spread pathogens and non local genetics). Given the natural pattern variations, perhaps photos could suffice instead of clipped scales.
Pertinent data such as time, place and conditions of capture/release, gender, size, weight, etc could be recorded and made public (perhaps with a time delay so hunters don't aggressively target the released animal too soon after release). Then hunters could review the list of released animals and report if any of their captures had been previously released
Then again, maybe this has already been done and I just don't know about it.
