Pedigrees/lineage tracking seems to me like something a lot of people in the aquarium trade/hobby would probably be interested in.
I think a pedigree system could work if done well and properly. But then we'd need some sort of elaborate "pure species" certification system in place. At most I'd think it'd help with the breeding of endangered fish or those on the CARES list to prevent too much inbreeding. Not too sure about the line breeding part tho...
Speaking of which...Who the hell gave him certification and why is this just now a thing? Excuse my language. I'm genuinely curious.
