For me, a little of both. We enjoy a nice meal of fresh trout, and also keep a few meals in the freezer for the winter months.
I release many that are hooked in a way the hook can be removed with minimal damage. However, the majority I've caught have the hook deep and I can't get it out without significant damage.
There is a predominant mentality here amongst many people that you HAVE to keep what you catch and if you won't eat it, some body will.
I see much of the same where I live and never have agreed with it.
