I Will Answer Anything You Dare To Ask

@Keraunos Salmon, Trout, Haddock, Cod, Tuna, Bass, Carp, Mackerel, Catfish, and stuff I can't remember what are called in English, like Kveite, Sild, Røye, Steinbit, Abbor, Gjedde, Rødspette, uuuuh that's all I can think of right now

Not bad for your first time. As a bit of constructive criticism: you seem to already have a really strong grasp on the ones humans eat of a lot of, so you may do well to branch out a bit and start to master the other fish-categories. There is a whole fish-world consisting of sharks and rays, for example, you could probably double your fish-count with about a week's preparation just by studying that alone.
