CommentsAs far as I can tell, the USGS NAS website does not list any introduced populations of the yellowfin goby this far north. I am relatively certain that the species ID is correct, as the identification characteristics for it match what the USGS site provides. I counted nine individuals within my immediate vicinity but there are definitely more. The attached images were taken by me, with one being taken last month, although I have also uploaded them to iNaturalist so they can be found there as well.
