Is frozen water suitable for rainbow trout?

Frozen water, or ice, is not suitable for rainbow trout as it can inhibit their ability to swim and access oxygen. Trout require liquid water to survive, and their habitat needs to provide sufficient oxygen levels. In freezing conditions, if the water is completely frozen, the trout would not be able to thrive. However, if the water is cold but not frozen solid, rainbow trout can still survive and thrive in colder temperatures.
