Abstract

In this study, length distribution, length-weight relationship, age, growth parameters, and reproduction of 331 Gobius niger collected monthly by trawling in the Sea of Marmara between October 2011-July 2014 were determined. The total length and weight distributions of the population varied from 6.2-14.2 cm and 2.85–36.25 g, respectively. The average length was found 10.28 cm and average weight was found 13.71 g. Black goby was distributed between 0-4 age groups. Otolith length-total length relationship was calculated as OL= 2.337*TL+0.143 (R2=0.76). Length-weight relationship were determined total, female, and male as W = 0.096*L3.084 (R²=0.89); females W= 0.010*L3.042 (R2=0.88); males W=0.005*L3.33 (R²=0.94) respectively. The growth parameters were calculated for the whole populations as L∞=15.31 cm K= 0.36 y-1 t0=-1.77 year, L∞=14.89 cm, K=0.35 y-1, t0=-1.97 year for females and L∞=1 4.65 cm, K=0.45 y-1, t0=-1.39 year for males. The natural mortality rate (M) was calculated as 0.82 year-1, total mortality rate (Z) was 1.33 year-1, and fishing mortality rate (F) was 0.51 year-1. The exploitation rate (E) of population was determined as 0.38 year-1. The first sexual maturity length of G. niger was found L50=9.58 cm. The reproduction period was indicated between March to July.

Özet

Bu çalışmada, Marmara Denizi’nden Ekim 2011-Temmuz 2014 tarihleri arasında algarna ile aylık olarak örneklenen 331 adet kömürcü kayabalığının, ve boy-ağırlık ilişkisi, yaş, büyüme, ve üreme özellikleri tespit edilmiştir. Populasyonun boy ve ağırlık dağılımları sırasıyla, 6,2-14,2 cm; 2,85-36,25 g arasında değişim göstermiştir. Ortalama boy 10,28±0,08 cm, ortalama ağırlık ise 13,71±0,34 g bulunmuştur. Kömürcü kayabalıkları 0-4 yaş grupları arasında dağılım göstermiştir. Otolit boyu-balık boyu ilişkisi OL= 2,337*TL+0,143 (R2=0,76) olarak hesaplanmıştır. Boy-ağırlık ilişki tüm bireylerde W = 0,096*L3,084(R²=0,89); dişilerde W= 0,010*L3,042 (R2=0,88); erkeklerde W=0,005*L3,33 (R² =0,94) olarak tespit edilmiştir. Büyüme parametreleri tüm popülasyon için L∞=15,31 cm K= 0,36 yıl-1, t0=-1,77 yıl; dişi bireyler için L∞=14,89 cm, K=0,35 yıl-1, t0=-1,97 yıl; erkek bireyler için L∞=14,65cm, K=0,45 yıl-1, t0=-1,39 yıl olarak belirlenmiştir. G. niger’in doğal ölüm oranı (M) 0,82 yıl-1, toplam ölüm oranı (Z) 1,33 yıl-1, balıkçılık ölüm oranı (F) 0,51 yıl-1 olarak hesaplanmıştır. Populasyonun sömürülme oranı (E) ise 0,38 yıl-1olarak belirlenmiştir. G. niger’in ilk eşeysel olgunluk boyu L50=9,58 cm olarak bulunmuştur. G. niger’in üreme döneminin Mart-Temmuz arasında olduğu belirlenmiştir.
