In this study, it is aimed to determine some basic parameters of the whiting (Merlangius merlangus) population in the Eastern Black Sea. As a result of 12 months sampling conducted between March 2017 and February 2018, a total of 1579 whiting were examined and their lengths ranged between 7.5 cm and 32.6 cm and the mean length was 14.49 ± 2.85 cm and their weights ranged between 2.68 g and 279.58 g, the mean weight was 26.05 ± 20.95 g. Length-weight relationship was found W=0,0046*L3,173. While the sex ratio (female/male) was found to be 1,31: 1, because of the chi-square test the difference was found to be significant. Age distribution was between 0 and VIII, growth parameters were determined as L∞=31,87 cm, K=0,130, t0=-3,071, W∞=271,01 g and Ø'=2,123, respectively. The first sexual maturity length of total samples (L50) was calculated as 13.19 cm. In the light of the data obtained, it has been observed that there is a catch that negatively affects the sustainability of Eastern Black Sea whiting stocks.

Çalışmada, Doğu Karadeniz’deki Mezgit (Merlangius merlangus) popülasyonunun bazı temel parametrelerinin belirlenmesi amaçlanmıştır. Mart 2017- Şubat 2018 tarihleri arasında yapılan 12 aylık örneklemede elde edilen ve incelenen 1579 adet mezgit balığının boylarının 7,5 cm ile 32,6 cm arasında dağılım gösterdiği ve ortalama boyun 14,49±2,85 cm olduğu, ağırlıklarının ise 2,68 g ile 279,58 g arasında dağılım gösterdiği ve ortalama ağırlığın 26,05±20,95 g olduğu bulunmuştur. Boy-ağırlık ilişkisi W=0,0046*L3,173 olarak saptanmıştır. Cinsiyet oranı (dişi/erkek) 1,31:1 ve yapılan χ2 testi sonucu farkın önemli olduğu tespit edilmiştir. Yaş dağılımı 0-VIII arasında, büyüme parametreleri L∞=31,87 cm, K=0,130, t0=-3,071, W∞=271,01 g ve Ø'=2,123 olarak belirlenmiştir. Toplam örneklerde ilk eşeysel olgunluk boyu (L50=13,19 cm) olarak hesaplanmıştır. Elde edilen veriler ışığında Doğu Karadeniz mezgit stoklarının sürdürülebilirliğini olumsuz yönde etkileyen bir avcılık söz konusu olduğu görülmüştür.
