Abstract

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).

İzmir Körfezi'nde (Türkiye'nin Ege Denizi Kıyısı) Dağılım Gösteren Başlıca Ticari Balık Türlerinin Boy-Ağırlık ve Boy-Boy İlişkileri / 2020-2021 Av Sezonu

Abstract

Bu çalışmada 30’u Sardina pilchardus, 54’ü Engraulis encrasicolus, 30’u Belone svetovidovi, 18’i Caranx rhonchus, 12’si Trachurus mediterraneus, 10’u Trachurus trachurus, 21’i Mullus Barbatus, 30’u Mullus surmuletus, 30’u Boopss boops, 35’i Oblada melanura, 46’sı Scomber colias, 22’si Scomber scombrus ve 28’i Solea solea olmak üzere toplam 366 adet örnek 2020-2021 balıkçılık sezonunda İzmir Körfezi (Türkiye’nin Ege Denizi kıyıları)’nde avlanan ticari balıkçılardan elde edilmiştir.
Caranx rhonchus, Scomber colias ve Solea solea için negatif allometri belirlenirken, Engraulis encrasicolus için pozitif allometri ve diğer 9 balık türü isometrik büyüme saptanmıştır.
Sonuçlar ayrıca incelenen tüm balık türleri için boy-boy ilişkilerinin yüksek düzeyde ilişkili olduğunu göstermiştir (r²>0,900, P<0,05).
