The Messinian salinity crisis (MSC) has already strongly affected the Mediterranean ecosystems from the beginning of the Messinian. Here, the Tortonian, Messinian, and Zanclean size distributions of the most common mesopelagic fish species are compared in order to test the hypothesis that the MSC impacted the size and hence the biomass of Mediterranean mesopelagic fish in the late Miocene. The results suggest that, with appropriate data, a size reduction can be detected during the Messinian that is possibly connected to the MSC restriction of Mediterranean–Atlantic connection. Indeed, these preliminary data suggest an increase otolith size of Ceratoscopelus in the Zanclean.
