Bass growth is faster in southern waters than in northern waters,primarily because the growing season is longer. For example, in fours years, the average Louisiana LMB reaches about 18"; and Indiana bass is about 13": while a Wisconson bass averages about 11". Metabolism of bass increases in warm waters and will feed more often and will seldom eat below 50average feeding is 68 to 80 however as temps increases the feeding declines. Although bass in the south grow and mature faster they rarly live as long as bass in colder temps,in southern waters bass occasionally reach 10 yrs in northern they will reach 15yrs.
Look at where the records are for trouphy bass all in the southern waters, yes each state has there own record but the big ones are all southern--and female.
