Which risk increases for salmon migrating upstream when unusually strong geomagnetic storms occur?

💡 Explanation

Geomagnetic storms disrupt the detection of the Earth's magnetic field, impairing their magnetic compass during migration, because it affects the sensing organ; navigation requires olfactory maps; therefore misdirection, disorientation risk increases via impaired senses of magnetic variation signals, rather than other metabolic effects.
