Well from someone who has been there and done it, I can tell you this much, not many of you know what the rules are, or how it works. Please don't take that as a dig, it isn't.
First anyone could catch a record, if your fishing the waters that hold them that is, and you could claim it, it's not hard, just long winded.
So here goes,
You have to have two Independent witnesses, not related to you in any way.
Your scales have to be checked by weights and measures, you then get a certificate to verify the scales.
Good clear photos of the fish, as an extra, i took the measurements of the fish, in length and girth, and photo's that showed the measurements.
We do need, as others have said, a list so we know the biggest of each species, simple as that. As a kid i used to know every coarse record weight, and the captor, it was something i felt was part of my fishing, and to catch a record was a dream as a kid. The fact I did catch a record, and the Roach, the record i had dreamt of, doesn't mean i am a great or known angler. I was in the right place at the right time.
Is the captor important ?? Yes, to a point, because without the captor you wouldn't have the record would you.
I wouldn't claim a record again, for a couple of reasons. The list is false IMHO. If you are going to have a list of record fish in this country, then it has to be for all species. The Cat fish isn't on the list, because of illegal stocking, that is the official verdict, yet the Zander and Grass Carp are, even when they have been illegally stocked as well, HOW does that work.
The other thing is when the BRFC changes members. If a new member joins, he or she may put a motion forward to have a record looked at and changed if they didn't agree with the record. I can tell you this as fact, as I was informed that some BRFC members were talking of returning my record to the list, I told them to forget it.
Angling has moved on, and as it has, the record list has lost it's appeal to most anglers, and having the same fish breaking the record a number of times, doesn't help, not when it is only a select few who may have the chance to fish for a record.
Claiming is easy, you don't have to be in the trade, or a known angler, you just have to have the correct Criteria to claim.
Hope that helps everyone.
