The stock structure of Bigeye scad in the Philippines is unknown. This profile covers the Bigeye scad (Selar crumenophthalmus)  fishery in the Philippines Fishery Management Area 5 (FMA - 5), encompassing the waters surrounding the province of  Palawan including the Calamianes Island Group (CIG), from Mindoro Strait, Cuyo Pass, West Sulu Sea, and western Palawan waters. FMAs were established in January 2019 (Fisheries Administrative Order 263) to focus on the ecosystem approach to fisheries management.

The general term matangbaka or matambaka,  and many other local names of the bigeye scad, is also applied to S. boops  (oxeye scad). In NSAP’s The Philippine Capture Fisheries Atlas  (Santos et al. 2017), both species share common names but are presented separately in areas where stock assessments occur.  Catch landing data of both species, however, are aggregated with other species under the “small pelagics” group.  In the Philippine Statistics Authority or PSA,  production volume is reported only for  “big-eyed scad (matangbaka)” (see OpenSTAT).  In FMA-5, other local name for this species are  "mat-an", "labiao", "samban", or "utdan".
