To be safe I would take the new catch to a different cleaners. I say that because cleaners are required to keep a log of what is brought in to be cleaned along with the name and address of the person they are doing the cleaning for. It may look suspicious if they see the same name or address or both on the same days log. They normally do not put the number of perch caught on the register/log but I believe they do record the wt. of the perch. The same name and address with 2 entries on the register in the same day and with wt's high enough may raise the red flag for that name or address.
