Same here grem if they die I like to keep them even if it for the dogs or something like catfish bait. It's usually stocked trout. But at least the trout are a put in and take fishery. Some of the creeks they stock just kill them when they get to hot so I rather see them caught an eaten. If they are in colder creeks and can live to have wild babies then definitely i would take better care of them and use a net.
Nothing hurts to practice CPR. If you do it right.
