The present work describes the feeding habits of the two-dominant species of family Mullidae; red mullet, Mullus barbatus barbatus Linnaeus, 1758 and striped red mullet, Mullus surmuletus Linnaeus, 1758 caught off the Egyptian Mediterranean coast throughout the period from January to December 2016. A total of 322 specimens of M. barbatus and 289 of M. surmuletus were investigated. The index of relative importance (IRI) indicated that Polychaeta was, for M. barbatus, the most important food item in all seasons with an average of 26.86%, followed by Decapoda, Amphipoda and Mysidacea. While, in the case of M. surmuletus, Mysidacea was the most preferred food item in all seasons with an average of 34.02%, then Amphipoda and Decapoda. According to the previous results, it can be inferred that the two Mullid species; M. barbatus and M. surmuletus from the Egyptian Mediterranean waters are specialist zooplanktivorous.

We examined genetic diversity and connectivity of two indigenous Mediterranean goatfish species (Mullus barbatus and M. surmuletus), and a Lessepsian migrant species (Upeneus moluccensis), across the Nile Delta outflow using two mitochondrial DNA markers (COI and cyt b). Genetic diversity was high for the two Mediterranean species but relatively lower for the migrant species, suggesting founder effects after invasion from the Red Sea. Confirmation of this hypothesis, however, would require comparison with populations of origin in the Red Sea and the Indo-West Pacific. AMOVA and network analyses revealed no genetic partitioning for all species, indicating the Nile outflow does not currently, and may not have historically, posed a significant barrier to larval dispersal in these goatfish despite a present-day temperature and salinity gradient along the Mediterranean coastline of Egypt.
