I saw the same thing happen last year about the same time, I talked to a couple of guys that happened to be there when that happened and was told that some fisherman cleans out his freezer every year at the start of the season and throws the fish left over from the last season in the river so it goes to some good use. I think it would be better to limit what you can eat and not waste the fish at all . If you look at the fish you can tell they have been frozen.
