HAHAHAHA
I am permanently disabled, so yeah - I have alot of free time.
if anybody cares, I DID find a
"Genetic Analysis of Northern and Southern Strains of North American Yellow Perch" - fish DNA tested were from both Wisconsin(wild and cultivated) and South Carolina(cultivated).
Both of the groups of Northern perch were virtually identical in their number of 'alleles', which is related to genetic diversity, with the cultivated group
very slightly greater in number.
The Southern perch's alleles numbered nearly
double(just slightly under) from that of the wild Northern perch...
In a nutshell(this study was pretty in-depth and 'tech-y', so I'll sum it up), even though the fish are genetically-speaking the SAME species, the fish in the Southern climate adapt to their environment
even at the DNA level. Greater genetic diversity results in healthier populations, no matter the species, be it fish or people.
Prior to this, I didn't think it made any difference - but
based on this information, my guess(now) is that a 19-inch largemouth bass in Texas probably WILL weigh more than a 19-inch bass in Massachusetts.
