Who said anything about limiting out? I never keep more than I can reasonably use, and in general I don't include freezing in that equation, either (not for game fish, anyway). From my position, abusing C&R to catch many times the limit (I've seen people brag of catching a hundred or more in one day), even when many of those released fish may die, is potentially worse than limiting out.
That said, the legal limits are set with sustainability in mind. If people are keeping too many fish to sustain the fishery, the state tends to reduce the limits.
And I'm not talking PURE sustenance, either. Sport is another consideration, to be sure, but it's enough that food is one of the reasons. My point is simply that sport alone isn't a good enough reason, IMO. Also, market fish in America suck if you don't live right on the coast. Supermarket fish are godawful, and even if you are lucky enough to have a dedicated fish market nearby (I currently don't, as they can't seem to stay in business in my area) it is crazy expensive for quality that still can't match fresh-caught.>>1517574>always keep
But no one said "always keep." That is absolutely not what "selectively release" means. It means being reasonable and responsible, not keeping fish beyond what you can use, or which are either too small or too big to be prime eating, but also not releasing fish that are unlikely to survive, even if you otherwise might have released it.
