Well, just for the sport of it. I don't kill those fishes.
Nope, we use a no-kill policy. We use a hooklink, we hook those fishes in the front of their mounths so that the damage stays minimal.
I started fishing with fishing for trout, but a carp's fight is much more explosive. Ok, it depends on the size of fish you are fishing for of course, but Belgium isn't a trout paradise. Sweden/ the U.K./ USA is much better though.
Here is the picture of my personal best

I caught that fish three years ago, it weighed 16,8 kilograms that's 37 lb.
