Answer:In 1861, the United States faced its greatest crisis to that time. The northern and southern states had become less and less alike--socially, economically, politically. The North had become increasingly industrial and commercial while the South had remained largely agricultural. More important than these differences, however, was African-American slavery. The "peculiar institution," more than any other single thing, separated the South from the North. Northerners generally wanted to limit the spread of slavery; some wanted to abolish it altogether. Southerners generally wanted to maintain and even expand the institution. Thus, slavery became the focal

The differences in the wild and hatcheries make it so the different salmon adapt differently and have different traits.
If salmon are split up into different habitats, one being in the wild and one being in captivity, they will eventually have different adaptations from each other and their offspring will develop traits that are better suited for their environment.
Wild salmon and salmon that are raised in captivity are going to be very different from each other. The salmon in captivity do not have to actively hunt for their food, be wary of certain predators, or may not want to reproduce.
Taking these factors into account, it is very possible that the salmon raised in captivity will have reduced reproductive success compared to the salmon that thrive in the wild. Along with this, they would most likely have many genetic differences from each other and other traits that better adapt to their living situations.
