The owner of a fishery near me put this sign up
A bit of context; these fisheries are for anglers, but across the country there are problems with eastern Europeans taking fish out to eat. Personally I've seen this first hand, and my brother often gets offered money for the contents of his keep net (one guy even suggested that 'keep net' meant they could keep them

) Some even use illegal netting and are taking out large amounts and putting them into vans.
These are businesses after all, the fish cost money, are the basis for revenue, and taking them is obviously illegal.
People are saying it is racist. Thoughts?
