Cod off Nomans Island

[Blue_Runner]

Ok, did some research. From what I read it sounds like they used cod and maybe pollock and/or hoki later on.

Today's fillet-o-fish:

The fish McDonald’s uses is now Hoki, a sustainable alternative to cod. This is sourced through Marine Stewardship Council certified fisheries, and comes from the seas around New Zealand. Yes, the Filet-o-Fish is cooked from frozen and does take a little longer than the other sandwiches, but hopefully it’s worth the wait. Some menu items are frozen to ensure they are at their best when they reach the restaurants. From mid November, McDonald's Filet-o-Fish will be prepared using Alaskan Pollock fish, which is sourced from Marine Stewardship Council certified fisheries. Fish Fingers will continue to be made from Hoki, also sourced from Marine Stewardship Council certified fisheries
