noun
oilfish
A deep-sea fish (Ruvettus pretiosus) known for its oily flesh, which can cause digestive issues if eaten in large quantities. Often labeled as バラムツ in markets.
バラムツは脂が多く、食べ過ぎるとお腹を壊すことがある。
Oilfish is very oily and can cause stomach upset if eaten in large amounts.
市場でバラムツを見かけたが、調理法がわからなかった。
I saw oilfish at the market, but I didn't know how to cook it.
Another deep-sea fish (Lepidocybium flavobrunneum) also called 'escolar' or 'butterfish', similarly oily and sometimes confused with バラムツ.
The name likely combines バラ (bara, 'rose') and ムツ (mutsu, 'gnomefish'), possibly from the fish's pinkish hue. The exact derivation is uncertain.
