My pleasure and yes, those are what we call big carps.

They use special light weight rods and to counter the resistance, one has to slowly play the fish, with the reel clutch on in case the fish breaks into a run. The bait is special maize balls with only one pip on the hook that hangs next to the bait. Carps don't eat, as they suck the bait up with the hook.
A very intricate system.
