First off I would like to start buy saying CPR is not a way of life, It is a choice!!! When a person manages to catch a large fish (20+lbs) and decides that they want to release it. Keep in mind that, the fish needs to be handled as little as possible, handled properly and, released as soon as possible to insure a better rate of survival. Of course these are just my takes on how they should and shouldn't be handled. Get the fish to the boat asap (or as fast as he will let you, LOL)!!! This will cut down on stress levels in the fish. Always hold a fish in a manner that gravity will do the least damage (they come from a ZERO gravity world). Support the head and belly of the fish while getting pics. One should never put his fingers or any other object in the gill area. Gill plates are not fish holding handles!!! Holding a large fish by his gill plates is the same as someone grabbing you by the lungs and holding you up off the ground. How well would you be able to breath if someone did that to you? (this is one of my pet-peaves) Taking pics, weighing, measuring and all shouldn't take more than a few minutes and he is swimming back to his home. PS. If you are going to keep the fish do it any way you want, this pretains to catch and release!!!
