Description: The king mackerel (Scomberomorus cavalla) is primarily a pelagic carnivore, feeding mostly on a wide variety of fishes, and some invertebrates, such as shrimp and squid. Greater than fifty species of fishes have been identified from the stomachs of king mackerel collected in the Gulf of Mexico, as reported from all currently available literature surveyed for the Gulf of Mexico Species Interaction (GoMexSI) project.
In this project, six spatially oriented sink food webs for the king mackerel, based on the spatial availability of diet data, were identified. This map shows king mackerel diet composition, in percent volume of each identifiable prey family, for each food web.
