I'll contrast with sibling comments. You're correct to raise caution towards fishing Pacific salmon, even in catch and release. Release mortality from one study I've found is about 25-40% https://www.sciencedirect.com/science/article/pii/S016578362... It's worse during high water temperatures. They're likely quite fatigued by the time they arrive.

That said, this caution is not always warranted generally. Location, species, and season significantly matter. In healthy ecosystems, there's no harm to the group even if the individual fish might not agree.
