9450 Faxonius rusticus Commerce Anecdotal N/A While native gamefish do feed on the non-native Faxonius rusticus, due to its low ratio of soft tissue to hard exoskeleton, F. rusticus provides a lower quality of food than many of the native invertebrate species it replaces. This leads to slower fish growth and reduced survival. 25552
