magnetoreception and migration navigation

The following paper talks about introducing fish to a strong magnetic field and that field changes their genes.

Candidate genes mediating magnetoreception in rainbow trout (Oncorhynchus mykiss)

I am not understanding how a magnetic field changes genes. It sounds like they are talking about DNA changes that lead to encoding different proteins. I need to revisit and understand gene expression better.

As I read it I thought they were going to release the fish back into the water after exposure and see if they migrate normally but it looks like they haven't taken the experiment that far yet.

※→ zetreque, et al,

Yes, I've seen other published papers that show result: "he data suggest that magnetic fields in excess of 15 Tesla have far-reaching effect on the genome."

(COMMENT)

This is interesting, but not totally unexpected. The bigger question is: Does the movement of a body through a strong magnetic field induce current flow anywhere in the body?

Most Respectfully,
