jack mackerel

Diet of the Australasian Gannet Morus serrator (Gr Gray) around New Zealand

Collections of gannet regurgitations at most of New Zealand's gannetries allowed the identification of major components in the gannet diet and an estimate of the total annual consumption of the most important prey species. Major species were pilchard (Sardinops neopilchardus), anchovy (Engraulis australis), saury (Scomberesox saurus), and jack mackerel (Trachurus novaezelandiae).
