Flyfishing for Carp in Denmark

Anyone who tried fishing for carp in Denmark?
Material about carp fishing seems so to gain popularity especially in the US. youtube channel's.

From what i can tell from my very restricted knowledge about carp behaviour is, that our carp are not feeding as vividly as in the warmer climates.

Anyone who has any tips for carp fishing in Denmark?

I'm thinking about sightfishing for carp passively by fishing with dryflies and nymphs, that's the dream; a little bit of twitching will enhance the fly fishing experience IMO.

as a back up plan I will try to feed the carp bread or boilies and use imitations.

I'm looking for insight in the feeding behaviour especially around invertibrates or other common carp foods.
