The Spread Of An Atlantic Fish Species, Pomadasys Incisus (Bowdich, 1825) (Osteichthyes: Haemulidae), Within The Mediterranean Sea With New Additional Records From The French Mediterranean Coast

For the first time three specimens belonging to the species Pomadasys incisus (Bowdich, 1825), the bastard grunt, were caught in the French Ligurian Sea. This subtropical species, which naturally entered the Mediterranean Sea through the Straits of Gibraltar in the first half of the nineteenth century, and is currently colonizing the whole Mediterranean coast except the Adriatic Sea, was until now unknown for this region. We reviewed its distribution after a compilation of the available literature, and tried to explain the spreading and the establishment of the bastard grunt as a Mediterranean species in light of the prevailing Mediterranean currents and the possible climate changes.
