Dissolved oxygen content in water is a function of both temperature and
salinity. Cooler water can hold more oxygen, and fresher water can hold more
oxygen. So I think Dustin's right, it all depends on what fishes you're
transporting. Any fish from a highland stream are almost always more fragile
than those from lowland systems.
