Leanght-weight relationship and condition factor of sardine (Sardina pilchardus) and european anchovy (Engraulis encrasicolus) from the Adriatic sea

Cilj ovog rada bio je utvrditi dužinsko-maseni odnos i kondiciju srdele i inćuna iz Jadranskog mora. Uzorkovanja su provedena okružujućom mrežom plivaricom tijekom travnja 2021. godine na području srednjeg Jadrana (Dugi otok). Prikupljeno je ukupno 100 uzoraka srdele i 110 uzoraka inćuna. Analiza dužinsko-masenog odnosa ukazala je na ukupan pozitivan alometrijski rast obje istraživane vrste (srdela: W= 0,004 x L3,167, R²= 0,861), (inćun: W= 0,002 x L3,405, R²= 0,936). Prosječni Fultonov faktor kondicije analiziranih srdela iznosio je CF= 0,699 ± 0,043, dok je CF inćuna iznosio 0,647 ± 0,037.The aim of this study was to determine the length-weight relationship and condition factor of sardine and anchovy from the Adriatic Sea. Samples were caught by a purse-seine net during April 2021 in the middle Adriatic Sea (Dugi otok). There were 100 samples of sardine and 110 samples of anchovy. Analysis of length-weight relationships indicated positive allometric growth for both species (sardine: W= 0,004 x L3,167, R²= 0,861), (anchovy: W= 0,002 x L3,405, R²= 0,936). The average Fulton’s condition factor of sardines was CF= 0,699 ± 0,043 and for anchovy CF = 0,647 ± 0,037
