Completely safe to eat. Could either be kudoa or tapioca disease.
Was the meat really soft and runny? Kudoa has an enzyme that immediately starts breaking down the flesh after the fish has died.
If the meat wasn't mushy and turning into pudding it probably wasn't Kudoa, but rather tapioca disease.
Watch closely for little blood spots in your pink meat, particularly around the belly meat. Some might also look like little white dots.
These little red spots if you dig will have a disc shaped cyst in them. It's actually not a tumour but rather a resting stage of a worm called anisakis.
I found them in a bunch of my pinks from this year that were up island. If you are smoking any fish I would recommend having your smoker to at least 200F for an hour to kill parasites. They won't kill you, and can't live in you (for long), but they'll make ya hella sick for up to 2 weeks and could require surgery if the infection they cause gets bad enough.
