If the only option is to fish carp focused waters then all anglers are going to be 'angling for carp' regardless of whether they are 'pleasure', 'specimen' or 'match'."Carpers rule stillwaters"
Utter garbage - most angling for Carp is conducted by pleasure and match anglers.
But it's true, lakes seem to be loosely divided into 'runs waters' with lots of small carp, and specimen waters with fewer big carp. Tackle restrictions tend to be in place in specimen lakes, but not always in runs lakes.
Though it only takes one big carp to mean that suddenly everyone needs a 42 inch net, and as carp do tend to grow quickly, unless they are actively removed then that will be the rule everywhere.
