Press on.
I mean, unless you're some kind of crazed, conk-o-maniac, meat fisherman and would suffer horrible nightmares and and PTSD when thinking about all the "meat" you "lost" by having a fish or two flop of on a long distance release, what would it matter? I mean, sure, there are guys out there who practice thier technique with the priest as much as they practice casting, and I'm sure having a trout or two flop off would kill many of these iron mongering, meat flinging, hardware hocking, freezer fillers. But hey, there but for the grace of God go we fly anglers, eh?
I did something similar about 8-10 years ago, I forgot to clip my net to the back of my vest before I left the truck. It was probably one of only a handful of times in a decade when I fished without one.
Of course, there could be but one outcome. I hooked what was easily the biggest brown of my life. Played him, got him close, and. . . predictably. . . reached for the net. . . Yeah.
He flopped off as I tried to land him by hand. I maintain it counts as a "catch", hey, I touched him so by international rules. . .

But of course I didn't get a measurement or a picture, which was too bad, but one way or another he was going back anyway so oh well.
Grouse.
