I think that if it meets all the physical characteristics of a trout, bluegill, etc, you should count it towards the record. If you get into genetic testing of things, I think you're opening a whole new can of worms. You'll have people claim they have the Lake Cumberland strain largemouth record vs the Lake Erie strain, or people will be calling for an asterisk next to a record because its a hybrid strain. And then you'll have to break down the hybrids based on whether it was modified through selective breeding or engineered in a lab.
