This study evaluated current hatchery and management practices that may influence the ability of Pacific steelhead trout (Oncorhynchus mykiss) to perceive or respond to geomagnetic fields.
In the past two decades, occurrences of summertime upwelling-driven low dissolved oxygen (DO) events, or hypoxia, have increased along the northeast Pacific coast.
The dynamics of the geomagnetic field in context of animal navigation is a promising avenue for understanding the how animals deal with an ever-changing environment.
