Resumo

The present note reports the first study of the Lessepsian migrant, bluespotted cornetfish Fistularia commersonii Rüppell, 1838 from the Gulf of Tunis based on 32 individuals. The male:female ratio was skewed towards females. The length-weight relationship exhibited an isometric growth. Morphometric and meristic characters, information on feeding habits and gonads were also provided. The eventual establishment of F. commersonii within the Mediterranean is then discussed according the available data on reproduction and growth.
