The brassy chub (*Kyphosus vaigiensis*), a robust, oval-shaped fish with a metallic sheen, is primarily found in tropical and subtropical waters of the Indo-Pacific, including reefs and rocky coastal areas. This herbivorous species is valued for its firm flesh and is commonly targeted by both commercial and artisanal fisheries. The top brassy chub fishing countries include Japan, Australia, and Indonesia, where the species is caught using nets, traps, and handlines, often as part of mixed reef fish catches. In Japan, brassy chub is locally known as "Mejina" and features in regional cuisine, while in Australia and Indonesia, it contributes to local food security and small-scale fishery economies. Although not a major export species, sustainable management is important due to its role in reef ecosystems and local livelihoods.
