For this trial, the bait was built using coarse birdfood (Red Factor) as the main part of the mix, with Robin Red at 10% inclusion. A fruit flavour and sweetener were added to support carp attraction.
The mix was produced as 15 × 12 mm barrels by a commercial roller, with 30 kg prepared for the trial. Supporting materials included a Robin Red-based groundbait (SuperRed) mixed 50/50 with oat groats, and a paste made from ground SuperRed to give a fast release of attraction around the hookbait.
