A species of bitterling-like fish; the name is a taxonomic term and may be encountered in field guides or ichthyology contexts.
Acheilognathus macropterus is a freshwater fish distributed in China and Vietnam.

The name literally means 'large bitterling' (大 + タナゴ). The kanji 鱮 is an obscure character for a type of carp-like fish.
