What did I eat?

We went to a very good Indian restaurant yesterday. I had king fish cooked in a banana leaf. It wasn't until the second or third mouthful that I realised I didn't know what king fish is. Unfortunately, neither does anyone else. It could be king mackerel (Scomberomorus cavalla);

one of the kingcroaker family (Menticirrhus americanus, Menticirrhus undulatus, Menticirrhus littoralis, or Menticirrhus saxatilis: the picture is of Menticirrhus saxatilis);

or else the narrow-barred Spanish mackerel (Scomberomorus commerson);

or the white croaker (Genyonemus lineatus: unlikely, as it only occurs in the Eastern Pacific);

or the perciform cobia (Rachycentron canadum);

the wahoo (Acanthocybium solandri);

the crevalle jack (caranx hippos);

the japanese meagre (Argyrosomus japonicus: I can only find this suitably inadequate photograph of it);

the yellowtail amberjack (seriola lalandi: this could be the California yellowtail (seriola lalandi dorsalis), the southern yellowtail (seriola lalandi lalandi) or the Asian yellowtail (seriola lalandi aureovitta));

the opah (lampris guttatus or lampris immaculatus: you may know this fish better as the Jerusalem haddock);

the silver gemfish (rexea solandri);

or the giant trevally (caranx ignobilis: pound for pound, one of the toughest fish to catch in the world, I'm told).

I'd say it was probably a scombrid, but apart from that can't go much further. Whatever it was, it was most tasty.
