As the water and air temps get stupid hot, don't forget to revive any fish you plan to release. It's something that should always be done....but especially important now. A popular technique is holding the tail and slowly moving the fish back and forth...in the water! Don't forget that part. You'd be surprised. When your victim is strong enough to swim away, on it's own...it will.
A less popular method is "mouth-to-mouth". Not sure how effective it is...but this guy made a bunch of money doing it, so I guess it's worth a try.
