Abstract

 In this study, the length-weight relationship (LWR) of 14 fish species including Merlangius merlangus (Linnaeus, 1758),Trachurus trachurus (Linnaeus, 1758), Mullus barbatus Linnaeus, 1758, Gobius niger Linnaeus, 1758, Scorpaena porcus (Linnaeus, 1758), Arnoglossus kessleri Schmidt, 1915, Uranoscopus scaber Linnaeus, 1758, Serranus hepatus (Linnaeus, 1758), Sygnathus thyphle Linnaeus, 1758, Aphia minuta (Risso, 1810), Trachinus draco Linnaeus, 1758, Parablennius tentacularis (Brünnich, 1768), Callionymus risso Lesueur 1814, Pomatoschistus marmoratus (Risso, 1810) caught from the western Black Sea coasts of Turkey was investigated. Sampling was carried out between 2017-2018 with a beam troll net with a span of 2 m. The sampling depth was between 10 m and 30 m. The minimum and maximum lengths and weights, length-weight relationships, a and b parameters and growth type (isometric or allometric) of the samples were determined. The b parameter of the length-weight relationship was determined between 2.58 and 3.586. A total of 3615 individuals belonging to 14 species were examined in the study. The most caugth species were M. barbatus (1118 individuals) and G. niger (1077 individuals). The coefficient of determination r2 value ranged from 0.79 (T. trachurus) to 0.99 (S. hepatus). It was determined that three species showed isometric growth, 4 species showed negative allometric growth and 7 species showed positive allometric growth.

 Bu çalışmada Batı Karadeniz kıyılarından yakalanan 14 balık türünün Merlangius merlangus (Linnaeus, 1758), Trachurus trachurus (Linnaeus, 1758), Mullus barbatus Linnaeus, 1758, Gobius niger Linnaeus, 1758, Scorpaena porcus (Linnaeus, 1758), Arnoglossus kessleri Schmidt, 1915, Uranoscopus scaber Linnaeus, 1758, Serranus hepatus (Linnaeus, 1758), Sygnathus thyphle Linnaeus, 1758, Aphia minuta (Risso, 1810), Trachinus draco Linnaeus, 1758, Parablennius tentacularis (Brünnich, 1768), Callionymus risso Lesueur 1814, Pomatoschistus marmoratus (Risso, 1810) boy-ağırlık ilişkisi belirlenmiştir. Örnekleme 2017-2018 yılları arasında 2 m açıklığa sahip beam troll ağıyla yapılmıştır. Örnekleme derinliği 10 m ile 30 m arasındadır. Örneklerin minimum ve maksimum boy ve ağırlıkları, boy-ağırlık ilişkileri, a ve b parametreleri ve büyüme tipi (izometrik veya allometrik) belirlenmiştir. Boy-ağırlık ilişkisinin b parametresi 2.58 ile 3.586 arasındadır. Çalışmada 14 türe ait toplam 3615 birey incelenmiştir. En çok yakalanan türler M. barbatus (1118 birey) ve G. niger (1077 birey) olmuştur. Belirleme katsayısı r2 değeri 0.79 (T. trachurus) ile 0.99 (S. hepatus) arasında değişmektedir. Üç türün izometrik, 4 türün negatif allometrik ve 7 türün pozitif allometrik büyüme gösterdiği tespit edilmiştir.
