Analysis of the vertebral number in gilt sardine Sardinella aurita Valenciennes, 1847 and allis shad Alosa fallax nilotica (Lacepede, 1803) from the eastern central Adriatic

Samples of the gilt sardine catches wwith a total of 50 individuals from the channel area (Hvar channel) and open waters (Palagruža Island) of the central Adriatic were analysed with respect to their number of vertebrae. The vertebral number in gilt sardines ranged from 47 to 49. Modal value of 48 vertebrae was observed in all the samples of gilt sardine catches. Samples of the alis shad catches with a total of 76 individuals from the inshore waters (Saldun and marina Bays) and offshore waters (Jabuka Island) were also analysed with respect to their number of vertebrae. The vertebral number of allis shad ranged from 54 to 57. Modal value of 57 vertebrae was observed in all the samples of the allis shad catches. There was no significant difference between the mean values of vertebrae for both species. It could be concluded that teh tested gilt sardine and allis shad samples from the investigated regions belongred to the same populations as regards their number of vertebrae, respectively.
