Length-Weight Relationship and Mortalities of Mullus barbatus ponticus Essipov, 1927 in the Central Black Sea, Turkey

Year 2017, Volume: 3 Issue: 2, 75 - 80, 01.12.2017

Abstract

A total of 1301 red mullet specimens were monthly collected from commercial gill/trammel net and bottom trawl fisheries, especially landings to Sinop fishing ports between September 2016 and February 2017. Total length and weight of red mullet specimens were ranged from 8.2 cm to 20.2 cm (average: 13.5 ±0.05 cm), and 5.6 g to 86.5 g (average: 28.2 ±0.36 g), respectively. The samples were grouped densely between 12 and 14 cm. The 34.4% of all samples in this study are under legal size. The LWR equation calculated was W = 0.008 × TL3.1076 (R2= 0.9591). Age groups of red mullets in the Central Black Sea were ranged from I to IV. Mean lengths according to age groups were 10.1, 14.02 ±0.22, 16.63 ±1.30 and 19.6 ±0.15, respectively. Also, von Bertalanffy Growth Parameters were L∞ = 19.21 ±1.55 cm, K = 0.68 ±0.27 year-1, t0 = -0.13 ±0.48. Mortalities (M, F and Z) and exploitation rate (E) of red mullet from the Black Sea were 0.335 year-1, 0.398 year-1, 0.733 year-1 and 0.54 year-1, respectively.

Abstract

Toplam 1301 barbunya balığı bireyi Eylül 2016-Şubat 2017 tarihleri arasında Sinop limanına getirilen, ticari kıyı uzatma ağları ve trol ağları ile yakalanan balıklardan aylık olarak örneklenmiştir. Barbunya balığı bireylerinin toplam boy ve ağırlıkları sırasıyla 8,220,2 cm (ortalama: 13,5 ±0,05 cm), ve 5,6-86,5 g (ortalama: 28,2 ±0,36 g) arasında değişmektedir. En fazla örneğin bulunduğu boy sınıfı 12-14 cm’dir. Çalışmada incelenen örneklerin %34,4’ü yasal boyun altındadır. Boy-ağırlık ilişkisi eşitliği W = 0,008 × TL3,1076 (R2= 0.9591) olarak hesaplanmıştır. Orta Karadeniz’de barbunya balığının yaş grupları I ve IV arasında olup, yaş gruplarına göre ortalama boylar sırasıyla; 10,1, 14,02 ±0,22, 16,63 ±1,30 ve 19,6 ±0,15 cm olarak belirlenmiştir. Von Bertalanffy büyüme parametreleri L∞= 19,21 ±1,55 cm, K = 0,68 ±0,27 yıl-1, t0 = -0,13 ±0,48 yıl-1 olarak hesaplanmıştır. Karadeniz’de barbunya balığının ölüm (M, F ve Z) ve sömürme oranı (E) sırasıyla; 0,335 yıl-1, 0,398 yıl-1, 0,733 yıl-1ve 0,54 yıl-1olarak hesaplanmıştır
