Question: What kind of fish is in filet o fish?

context: In November 2007, McDonald's lowered the use of New Zealand hoki and increased the use of Alaskan pollock, due to declining New Zealand hoki fishery sustainability and large cutbacks in the total allowable commercial catch of hoki by the New Zealand Ministry of Fisheries - from 250,000 tonnes in 1997 to 90,000 tonnes in 2007. McDonald's originally used Atlantic cod, before declining cod catches forced McDonald's to find sustainable fish elsewhere. McDonald's is trying to maintain fish only from areas certified as sustainable by the Marine Stewardship Council, but that is becoming more difficult each year. Hoki is still a major ingredient.
