Not a huge factor anyway since natural repro in WI is only estimated to be about 2%. That is why catch and release is important, even in a put and take fishery. There is nothing wrong with selective harvest but getting some nice photos and releasing them is a reward in itself. Let em go let em grow, especially if they do not have any fin or maxillary clips! There is a great deal of catch and release practiced in other sports (musky especially) so why not for steelhead and browns?
I know the Charter boats take a lot of fish but there isnt much we can do aside from cutting down to a 3 fish limit (which i support by the way). As with most hunting and fishing, the key is not to get greedy. Tight lines.
