I would either mark them as not wild or not the correct location. I can see the point about local small fish markets but unless you know how far their boat went from shore you can’t set the uncertainty buffer correctly anyway. I think marking not wild/captive makes a bit more sense than mapped wrong because the organism WAS found where observed, it just was brought there by a person. Also there is the potential that someday the ‘not wild’ observations will still be able to get research grade or train the algorithm whereas ‘mapped wrong’ locations are basically useless for most things
