Without mentioning any names, a great many famous anglers of the past, and present for that matter have hooked and landed fish a second time for the sake of the cameras.
I have never done it personally but I have known some very famous names who have asked other anglers who have caught big fish to loan them the fish, as they have to produce a feature.
Some years ago I did a feature for the guys at Improve Your Coarse Fishing. I could have gone there the night before and keepnetted a number of big roach and kept them for the feature so that the editor could have had their pictures. I couldn't get there the night before because of work committments. I am proud of the fact that I was able to catch a 1lb 14 oz roach for the cameras. There was no posing of the shots.
It all took place as it happened.
