WHAT YOU NEED TO CLAIM A RECORD
The weighing of any potential record fish should be witnessed by at least two other people. If the angler is alone, the BRFC will accept a written affidavit (legal oath).
Good-quality photos should show
the fish lying next to an identifiable object and with the angler holding the fish in the normal manner or, in the case of a very large fish, posing beside it.
Your scales must weigh in appropriate divisions (generally ounces for larger coarse fish) and be fully calibrated after the capture by a weights and measures team.
