I was out fishing a muddy creek last night, and saw a gar cruising top-water. After a couple casts with a small yellow popper, he took it, and I knew the fight was on…
… but it wasn’t. This thing was over 2 foot long, but didn’t give much of a fight at all (on my 5 weight). I just basically drug him in to the bank.
I haven’t caught a gar yet that didn’t put up a decent battle. But I fish a lot of carp as well, and occasionally I’ll have one of them roll over on his side and come in without a fight. I would wonder if it had more to do with water conditions than the species. I know extremes of water temp can make any fish lethergic (the lazy carp I’ve caught have all come out of pretty cold water). Other than that I couldn’t say why your gar went so quietly, but I can tell you they aren’t all that way.
Maybe it wasn’t healthy. I have never caught a gar that didn’t go psycho on me. They jump, spin, tail-walk, hiss, dive for the bottom, and everything in between. It’s like freshwater Tarpon or Barracuda, sort of.
