The intraspecific geographical variability of horse mackerel Trachurus trachurus (L.) in the West African shelf waters

[摘要] An attempt to distinguish local stocks of horse mackerel was made basing both on the comparison of morphological features of fish from three West African shelf regions (Ifni: 28°34′-29°52′N, Cap Blanc: 21°00′-24°52′N, Namibia: 22°34′-26°08′S) and on the literature data.
