Trout feed face forward as well...but catching them is predicated on some type of bait (worm, dry fly, nymph, etc). The bait looks/appears to the trout as something worthwhile. Such is the idea of “bait” (i.e. a baited hook). A carp will ingest a baited hook if the attractant appears worthwhile. If they are snagged/foul hooked, so be it.
