There are millions of miles of self sustaining wild trout water that don’t need stocked trout to meet that objective.
Look, I’m not against stocked trout in certain places. I just don’t understand putting them in places to compete with wild trout and in stretches of water where they can’t even be kept. A lot of them die after being caught anyways, they can’t handle any stress. Put the planters in the lakes by the tourist areas and campgrounds and such. Leave the C&R water for wild trout to prosper.
