Some biological aspects of White seabream, Diplodus sargus (Linnaeus, 1758) from the northeastern Aegean Sea, Türkiye

Abstract

In the study, the age, growth, mortality parameters and length-weight relationship parameters of Diplodus sargus (white seabream) collected by a small-scale fisherman between August 2020 and July 2021 along the northeastern coast of Aegean Sea (Türkiye coast), were investigated. D. sargus had a range of total length and weight from 14.3 cm to 36.7 cm and from 50.5 g to 836.5 g, respectively. The length-weight relationships (LWRs) were calculated as W=0.02368*L2.881 for females, W = 0.01847*L2.959 for males and W = 0.01989*TL2.936 for both sexes. Using data from fish scales, the maximum age was determined to be 11 years. von Bertalanffy growth parameters have been calculated as follows L∞=39.01 cm TL, K=0.13 year-1, and t0= -2.58 year for both sexes combined. Total (T), natural (N) and fishing (F) mortalities were defined as Z: 0.83 year-1, M: 0.33 year-1 and F: 0.50 year-1 for both sexes combined. The exploitation rate (E) was calculated as 0.70, 0.44 and 0.60 for females, males and combined, respectively.

Öz

Bu çalışmada, Ağustos 2020 ve Temmuz 2021 tarihleri arasında Ege Denizi'nin kuzeydoğu kıyılarında (Türkiye kıyıları) küçük ölçekli bir balıkçı tarafından toplanan Diplodus sargus'un (Sargos) yaş, büyüme, ölüm parametreleri ve boy-ağırlık ilişkisi parametreleri incelenmiştir. D.sargus'un toplam uzunluğu 14,3 cm ila 36,7 cm ve ağırlığı 50,5 g ila 836,5 g arasında değişmektedir. Boy ağırlık ilişkisi dişiler için W = 0.02368*L2.881, erkekler için W = 0.01847*L2.959 ve her iki cinsiyet için W = 0.01989*TL2.936 olarak tahmin edilmiştir. Balık pullarından hesaplanan yaş verileri maksimum yaşın 11 olduğunu göstermiştir. Belirlenen büyüme parametresi değerleri tüm bireyler için L∞=39.01 cm, K=0.13 yıl-1, t0= -2.58 yıl olarak belirlenmiştir. Toplam ölüm (Z), doğal ölüm (M) ve balıkçılık ölümü (F) tüm bireyler için Z: 0.83 yıl-1, M: 0.33 yıl-1 ve F: 0.50 yıl-1 olarak belirlenmiştir. Sömürülme oranı (E) dişiler, erkekler ve tüm bireyler için sırasıyla 0.70, 0.44 ve 0.60 olarak hesaplanmıştır.
