I got this group of tosai on Friday and the shipment was lost at the airport for several hours on the runway, but I think that additional stress is only secondary to the issue at hand.
The SU arrived with a brown patch near the caudal peduncle on the fish's left side. it is marginally visible in the video above and the color of the sumi also looks funky in this area. The group is in QT currently salted at 0.3%. Over the last day the SU has gotten pink along the dorsal area and appears to be losing scales in the affected area. Treated topically with iodine, but not sure what I am dealing with. I suspected it was a old shipping bruise from coming from Japan.
thoughts or suggestions welcome.
