There are several species of Hyporhamphus which it might be. Your suggestion is likely, but can't be sure without a more detailed photo. I'd record it as Hyporhamphus sp.
Not sure how the database works, but looks like it isn't reliable for IDs then. A quick look in the "field guide" shows a wrong ID for bream, but no idea how to correct that.
Great action shot anyway! I assume something was chasing it - maybe salmon?
Yes a couple of schools of fish in the area Salmon and Tailor working with the birds. We need a moderator on the fish to change the Data I can do it on the Birds and Butterfly etc but not on the fish.
