Landing Fish on a Kayak

[SAR]

I'm new to the sport and I'm trying to learn as much as I can before I start fishing from my kayak. Right now I'm in the phase of taking my kayak out on the ocean and getting comfortable with the conditions, I'm also talking with as many fishermen as I can. My question for you is what is the process for safely landing larger fish from the kayak? I've seen people with gaffs and nets but I haven't actually seen a fish landed yet. Also I read a post here over the weekend where someone talked about bleeding and cleaning his yt on the water. Is that common and what are the advantages/disadvantages of doing that? Thanks!
