摘要

The stomachs of 205 king mackerel, Scomberomorus caralla (Cuvier), collected in Ohslow Bay, North Carolina were examined for food items. The stomach contents of the 113 stomachs containing food were composed mainly of fish. The dominant fishes were Atlantic menhaden, Brevoortia tyrannus (35% occurrence) and Atlantic thread herring, Opisthonema oglinum (28% occurrence). Other fishes and invertehrates ranked from 14% to less than 1% in occurrence. Atlantic menhaden and Atlantic thread herring were primarily dominant in the stomachs of king mackerel collected during the spring and summer months. Those collected during the fall months had ingested a wider variety of forage with Atlantic menhaden and Atlantic thread herring being of minor importance.
