Feeding habit of yellowfin black seabream, acanthopagrus latus in hiroshima bay

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 st...
