Length-Weight and Length-Length Relationships of the Main Commercial Fish Species in Izmir Bay (Aegean Sea Coast of Turkey) / 2020-2021 Fishing Season

In this study, a total of 366 samples were collected and 30 of them belonged to Sardina pilchardus, 54 of Engraulis encrasicolus, 30 of Belone svetovidovi, 18 of Caranx rhonchus, 12 of Trachurus mediterraneus, 10 of Trachurus trachurus, 21 of Mullus Barbatus, 30 of Mullus surmuletus, 30 of Boopss boops, 35 of Oblada melanura, 46 of Scomber colias, 22 of Scomber scombrus and 28 of Solea solea, were obtained by commercial fishermen in the Izmir Bay (Aegean sea coast of Turkey) during period of 2020 and 2021 fishing season. Negative allometry was determined for Caranx rhonchus, Scomber colias and Solea solea while positive allometry was present for Engraulis encrasicolus and the remaining 9 fish species have isometric growth. The results indicated further that the length-length relationships were highly correlated for all examined fish species (r²>0.900, P<0.05).
