5 years ago I looked into tags that were genotyped more than once with genotypes that don’t match each other. There are 6 fish, 12 capture events, each fish was captured and genotyped at least twice.
So we have a set of pairs and for each pair, one of the capture events is from 2015, when we had to scan the tags in the lab at the beginning of the day because we didn’t have an underwater housing. This raises a red flag for me that maybe these are not actually the tags that were used for these fish, if the tags got mixed up in the tray of tags we were inserting in order. The difficulty is that if the tags are out of order, they are most likely still inserted in a fish that is on the same anemone or nearby. Both fish in a pair come from the same site.
Possible solutions:
1) Do these fish match to other fish captured that day in 2015? I doubt this is the case, but I can double check the id analysis.
2) We could remove the tag_id from these 2015 fish that are questionable and put it in the notes column, then they would still be in the pool of candidate fish.
...that have been genotyped more than once and make sure they are genetic recaptures or make notes why not. Also make notes that pit scanner was checked for type-os.
