I've made a thread on this before and as in my avatar and other pics before I was told, I no longer hold fish like that. It was an honest mistake, although I don't see how it 'chokes' a fish and how there's any more chance of dropping it than when cradling it, I now know there's better ways to do it so all the pics I take from now on are either in a landing net or on a unhooking mat as I rarely have someone fishing with me to take a photo of 'cradling' a fish.
Unless they are small fish that are swung to hand I tend to avoid holding fish as much as it can. I will unhook the fish in the landing net and then either put it back in the water or into my keep net using the landing net only. My view is the less we handle fish means less chance of doing damage to them. If I want a picture I will take one with the fish still in the net and try to get something like a reel or float in the shot to use as a reference for size. I no longer see the point of a picture of me holding a fish
In 60 years of fishing, I've never held a fish like that. If you are holding something between fingers and thumb, the heavier it is, the harder you have to pinch. The harder you pinch, the more the likelihood of causing damage to internal organs.
For me if you are going to hold them in one had doing so horizontally distributes their weight better so puts less pressure/weight m on you and them. Good to do so over the water, the net or your lap as well just on the off chance you drop them although once you develop a technique I find you don’t drop many, apologies to those early fish I caught as a youngster ?
Then if they’re bigger then I find a cradle grip is better or just laid in the net. Always knelt down as well just in case you stack it although luckily I’m of an age where my balance hasn’t gone yet ?
Quite a bit bigger and I just leave them in the net and take some of their weight with the net rather than have their full weight on the ground plus you can quickly lift the net if they move.
It’s almost as important to hang onto some bigger fish for a little while in the margins to revive them if they’ve scrapped a bit. There’s also something quite satisfying feeling their power through your arm once they are ready to go.
Others may have more lax or more stringent methods but such methods have always seen the fish go back strongly.
