Sažetak
In this study recent demographic structure and distribution of fish species Zeus faber in the Adriatic Sea is investigated and compared with demographic structure and distribution during 1948-49. The presence of John Dory in the Adriatic sea was recorded in depth range from 21 - 239 m, with higest biomass indices at depth between 50 - 100 m. The length frequency distribution, length - weight relationship, sex ratio and the length of first sexual maturity were determined. Results, based on data from "Hvar" expedition 1948-49 and MEDITS surveys 1996-98, showed that in fifty years interval index of biomass and area of distribution of species in Adriatic Sea have been reduced and the demographic structure of population changed. Negative changes described in the paper indicate an overfishing of the species Zeus faber in the Adriatic Sea.
