I imagine the fjords are very much improved by the absence of large cruise ships with their tenders belching out diesel fumes. We cruised there and were shocked at the amount of air pollution showing in the high sided fjords. Gave up cruising because of the obvious effects on the environment.

Actually it is not quite true that E. huxleyi is not harmful for the farmed fish. E. huxleyi does not produce toxins per se when blooming, like it does Chrysochromulina. However, high concentrations and densities during blooms of E. huxleyi causes mechanical damages to fish gills due to sharp calcite exoskeleton, which can actually cause mass mortality of fish.
