I gillnetted the mouth of the Copper for ten years. When the up river escapement goal is met fisherman are allowed to fish long hours. It's only fair because they lost a lot of money so we could have good dipping early in the year.The little fish with the marks are what we called squirts. The ones that make it thru the gillnet. The one in five that are big and no marks are the ones that made it around the gillnets.
Good Luck, Riverlover
