^And this is why I've been a member for three years and hardly post.
Because we all know that a six inch blue cat fingerling will be 80 pounds in a year and a half, it's not like it takes 20-25 years to achieve that tremendous size or anything. It's not like the vast majority of blues are often (not always) the exact same size bracket as channels where the species are conspecific. It's not like the three largest Ictalurus fish species are endemic to similar, but parallel habitats that allows blues to achieve greater size than channels, and channels to get larger than whites. It's not like the same three fish species introduced to the same body of water will all end up achieving roughly the same maximum size in said body of water, assuming the body of water and it's ability to support fauna (read: not artificially supplemented by man in a place such as a fish farm) is small enough to limit the size of the larger species.
Yeah, they can't be compared at all. Sorry.
