Roughly 3-4 lbs, didn't weigh him. Strong fish though
Little bigger, maybe 4-5lbs.
After another bit of a lull, I saw some more activity and promptly cast my fly nearby. After waiting, I thought maybe I had spooked them when my line gave a tug, then tightened up. I strip-set, and immediately knew that I had hooked a HORSE of a Carp. Told my father to grab the net and get the scale ready, as this was gonna be a long battle haha. Indeed it was, a long, 20-25 minute fight with a fish that refused to relent. Took me into my backing quite a few times on long runs, and for a while I couldn't budge him. When he was tiring out and in typical Carp fashion, every time we'd get him close enough to net him, he'd freak out and surge ahead. We finally got him into the net, unhooked him and weighed him: 20.4 lbs
After a couple quick pics, I set him free to fight again. He still had quite a lot of fight in him, and he let me know with a tail whack and splash LOL. So thats how my day went. That one tired me out as much as I tired him out. Not a bad day of fly fishing I'd say! Big reason why I love to catch them on flies, such a different experience and such a harder fight!
You have come a long ways in your flyfishing career in a very short time! I told you it was fun to catch almost anything (except yourself!) on a flyrod and it is now all coming true for you. In years past the old flyrod purists would poo-poo catching a big carp on a flyrod as they are not considered a noble game fish. I'd bet you a dollar that most of those guys have not hooked into a good strong carp with a flyrod before. However, during the past few years the sport of flyfishing for carps has become very popular in many parts of the US and flyrodding for carp has become very popular. I used to get very strange and questioning looks from bait fishermen when I show up at the stream side or pond with a long and slender flyrod and most of those guys were amused, that is until I hooked into a good fish and they would gather around to see how you can catch a carp without the traditional corn and live baits.
