Of the six alternative species offered, rainbow trout accounted for 22% of all free fish given to shoppers, closely followed by hake (21%). Despite recent high-profile campaigns to boost mackerel consumption in the UK, mackerel was chosen least often, accounting for just 11% of free fish ­given away.
