Yellowfin black seabream, Acanthopagrus latus is a common Sparidae fish inhabiting Hiroshima Bay. In addition, Black seabream, Acanthopagrus schlegelii is a closely related species to A. Latus with the long history of stock enhancement especially in Hiroshima Bay and Japan in general. Hence. this study aims to contribute fundamental information on feeding habits and species management that can help maintaining sustainable fisheries in Hiroshima Bay. A total number of 324 alimentary tracts were removed from individuals sampling starting in March 2011 until February 2012 from Kusatsu fish market and angling tournament.
