The cells will make some sort of reaction, there's no doubt about it. But for a bass I believe that their cells will stay the same or shrink over time.
Bass are strong fish and they usually do well when there's a change in conditions made in the environment. But it depends on what this river has in it and if it leads to bigger opened waters.
If there's a shortage of food sources for the bass it'll have to adapt quickly or it'll die from the predators in the area. If there isn't any places the Bass can lay their eggs (reproduce) its population will die in that river.
There also competition. In that river it could have socked eye salmon in it or catfish even pikes. So the Bass cells would stay the same.

Explanation;
-According to the endosymbiotic theory; mitochondria and chloroplasts contain their own circular DNA, similar to DNA in Bacteria, Both mitochondria and chloroplasts are surrounded by two membranes: inner and outer membrane, mitochondria are about the same size as bacteria and also mitochondria appear to have been derived from purple bacteria and chloroplasts derived from photosynthetic bacteria.
Any change or random error in a DNA sequence is called a mutation.
