I was browsing reddit and noticed someone had posted an image that listed the "dos" and "don'ts" of catch and release. In the image it said that for deep hooked fish you should cut the leader line close to the hook. My question is that I have heard conflicting things about where to cut the line for a hook that you cannot seem to retrieve. I have heard that you should leave some line so that the hook is always pulled taught by the water as the fish swims, and I've also heard people say what this poster is saying. I've also seen people say you gotta take it out through the side gills, but I'm not sure I'm confident enough to do that. Which do you do/believe and why? I would like to learn more and make sure that I am doing/telling others to do what is best for the fish.
