What type of fish is in McDonald's Fillett-o-Fish?

?

Pollock

Just in case you were wondering what a Pollock is.

Oh come on, everyone knows that McDonald’s products are made from Soylent Green.

BigMackerel?

Seems to be some kind of square haddock. What kind of animal does kebab meat come from? “Some kind of cylindrical goat” - Alexei Sayle

Boooo!

I would think the better question would be “What kind of fish isn’t in the Fillet-o-Fish?”
