Then comes observation.
Carp are usually fairly cooperative in that they cruise, bask, roll, jump etc.
While any standard carp fishing approach might produce results, one of the most effective is 'stalking'. Having found the fish, it is essential that they be approached ultra-cautiously. If the nature of the bait permits, a stringer might be incorporated. If the carp in my chosen water behave typically, they will move to the plateau when a nice, mellow south-west wind springs up. If the wind is already blowing, which means carp will probably already be there, I will dispense with free feed and rely solely on stringers.
