Inshore versus offshore length distribution of round sardinella (Sardinella aurita) in the middle eastern Adriatic Sea

Round sardinella, Sardinella aurita specimens (N= 2,033) were caught in inshore (Virsko more) and offshore waters (Dugi otok) of the eastern middle Adriatic Sea by commercial purse seine, monthly from November 2007 to January 2009. Out of all specimens, 983 were male (48.4%), 1,021 were female (50.2%) and 29 (1.4%) were undetermined specimens, giving an overall sex ratio of m/f=0.96. Round sardinella specimens from inshore waters (N=526) and offshore waters (N= 1,507) showed total length (LT) range 13.0-32.5 cm and 10.0-30.0 cm, respectively. In total, they showed positive allometry (b=3.2266). Fulton's mean condition factor for round sardinella from inshore waters was K = 0.76 plus or minus 0.23, and for samples from offshore waters, it was K = 0.73 plus or minus 0.05. Females indicated better condition (K = 0.75 plus or minus 0.05) in both analyzed areas than males (K = 0.74 plus or minus 0.05).Original Abstract: U radu se usporeduje duzinski sastav, duzinsko maseni odnos i kondicija srdele goleme Sardinella aurita iz obalnog (Virsko more) i otvorenog (Dugi otok) mora istocnog dijela srednjeg Jadrana. U svrhu navedenih istrazivanja su koristeni mjesecni uzorci iz lovina plivarice ostvarenih tijekom razdoblja studeni 2007.- sijecanj 2009. god. Ukupno je analizirano 2 033 jedinki, od cega 983 muzjaka, 1021 zenka i 29 jedinki kojima nije bilo moguce odrediti spol. Odnos spolova je iznosio m/z=0,96. Totalne duzine (LT) jedinki iz uzoraka lovina obalnog mora (N=526) su kolebale od 13,0 do 32,5 cm, te od 10,0 do 30,0 cm kod jedinki iz otvorenog mora (N=1507). Ukupno su jedinke pokazale pozitivan_alometrijski rast (b=3,2266). Kubicni faktor kondicije (K) je za jedinke iz obalnog mora iznosio K = 0,76 plus or minus 0,23 a za srdelu golemu s podrucja otvorenog mora je bio K = 0,73 plus or minus 0,05. Zenke su pokazale bolju kondiciju (K = 0,75 plus or minus 0,05) od muzjaka (K = 0,74 plus or minus 0,05) u oba analizirana podrucja.
