I have a study system where I’m doing a capture recapture analysis. I mark fish in one year and I’m recapturing a subset of them the next year.
I only have 2 capture events. Since a lot of time has passed, relative to the fish, between the two episode of recapture, I cannot assume a closed population model. Is there an alternative?
What mark-recapture model would be best for this situation given that I want to compute a recapture probability?
