Might be. Over the last few years I have been successful in bagging some geese. Almost all Cacklers with one Aleutian Cackler. The Aleutian was close to inedible.All were taken on the Opener so I think they had all recently come from the Far North. I think that the Aleutian had fed on different plants and that is what changed its taste. Probably more of its diet was sea-influenced as they nest on the islands. That might be the same thing as is happening with the smelt.
