How melanosis can appear so fast? These pictures were taken from a SPF broodstock coming from 20h flight. Assuming that no hatchery is going to pack a $130 animal with necrosis and high vibriosis, what is the time frame you have seen between determine high vibrio countings and start to see melanosis like this animal? Those necrosis, remembering TSV, were developed in 18oC water and I wondering if someone has any thoughts about this. Thanks for any insight!
