noun
A deep-sea rockfish species (Sebastes matsubarae) found in Japanese waters. Also referred to as 赤魚鯛 (あこうだい) in some contexts.
See also: 赤魚鯛
アコウは高級魚として知られている。
Matsubara's red rockfish is known as a high-grade fish.
この辺りの深海ではアコウがよく獲れる。
Matsubara's red rockfish is often caught in the deep sea around here.
Often used interchangeably with アコウ, but 赤魚鯛 can specifically refer to the same fish or a closely related species in culinary contexts.
The name likely derives from the reddish coloration of the fish (赤 'red' + 魚 'fish'), but the exact origin is uncertain.
