    Body morphometric characteristics and otolith shape described by elliptic Fourier descriptors analyses were carried out on European anchovy (Engraulis encrasicolus) samples collected from six locations in Algerian waters during the acoustic survey ALPEL2018 (south-western Mediterranean Sea, GFCM-GSA04). The discriminant analysis was applied over twelve morphometric body distances and 31 normalized elliptic Fourier descriptors. It highlighted significant difference between areas but with high overlapping. No significant difference was detected between males and females, or right and left otoliths. Hierarchical clustering analysis conducted on the mean form of body and otolith shape showed a clear geographical cline. The results indicate that the geographical trend is present with a high level of overlapping between the near areas, suggesting that European anchovies in Algerian waters are not completely isolated.Morfometrijske karakteristike tijela i oblik otolita opisane eliptičkim Fourierovim deskriptorima analize su provedene na uzorcima europskog inćuna (Engraulis encrasicolus) prikupljenim sa Å”est lokacija u alžirskim vodama tijekom akustičkog istraživanja ALPEL2018 (jugozapadno Sredozemno more, GFCM-GSA04). Diskriminantna analiza primijenjena je na dvanaest morfometrijskih udaljenosti tijela i 31 normalizirani eliptički Fourier deskriptor. NaglaÅ”ena je značajna razlika između područja, ali s velikim preklapanjem. Nije otkrivena značajna razlika između mužjaka i ženki, odnosno desnog i lijevog otolita. Provedena hijerarhijska klasterska analiza srednjeg oblika tijela i oblika otolita pokazala je jasnu geografsku klinu. Rezultati pokazuju da je geografski trend prisutan s visokom razinom preklapanja između obližnjih područja, Å”to navodi da europski inćuni u alžirskim vodama nisu potpuno izolirani
