Secret bait?

Rumour has it that a special secret Nutrabaits boilie mix has been taking the carp pond apart in recent weeks. The problem is that no-one knows what the mix is. It has been so successful however that some anglers are prepared to go to any lengths to find the secret, including following Nutrabaits' employees as they bait up.
But it is such a well guarded sectret that after fishing all unused bait must be retrieved and returned to Canklow to be reprocessed.

Is he retieving his bait or using his maggot to atract the bigger carp? (editor)
