I have to throw this open because I don't know who could answer the question.
Is there somebody in the supply chain who is really the pivot point for the veracity of the labelling of the fish, or somebody who could be, if you like, deputized to be responsible for the accuracy of the label?
I would look at, for instance, the wholesaler who would perhaps buy from the processor and then distribute to everybody else, but I don't know. Are there any suggestions there?
