The white cysts spawnout is decribing and in is StormiN's photos are the myxosporidian parasite Heneguya Salminicola (same family as Kudoa Thrysites but does not destroy meet to same degree).
The white fluid that expels from the cysts is actually loaded with the parasite spores. H. Salminicola rarely causes mortality in the fish, it just makes the flesh less appetizing. No adverse effects if consumed, just cook up and enjoy with a glass of fine wine.
