Abstract

This study aimed to determine the gender-related changes in the morphological and morphometric properties of the scales for Mesogobius batrachocephalus inhabiting Şile coast of the Black Sea. In this study, a total of 32 individuals (n♀= 16, n♂=16) were evaluated. The minimum and maximum total length and weight of the fish samples were in the range of 17.6- 27.7 cm and 46.6 - 231.0 g, respectively. The scales in different body regions were evaluated for female and male specimens separately. The morphological features such as scale size and scale shape were identified as distinguishing features between both female-male specimens and specified regions. The other morphological features (scale focus position, circuli, radii type, and the rostral and kaudal margin) of the scale were showed similar characteristics both in females-males and specified regions. When the scales in the body regions of M. batrachocephalus specimens were compared, the statistically significant differences were determined between the morphometric values (width, area, and perimeter) of females and males for 1., 4. and 5. Regions (P<0.05). In this study, data on scale morphology and morphometry of M. batrachocephalus was presented for the first time. As a result of the study, it was determined that female and male individuals differ in terms of these characteristics. For this reason, it is suggested that scale morphology and morphometry, which have an important place in phylogenetic studies, should be evaluated separately in both female and male individuals of M. batrachocephalus.

Özet

Bu çalışmanın amacı Karadeniz’in Şile kıyılarında yaşayan Mesogobius batrachocephalus türünün vücudunun farklı bölgelerinde bulunan pullarının morfolojik ve morfometrik özelliklerinin cinsiyete bağlı değişimlerini tespit etmektir. Bu çalışma kapsamında, toplam 32 birey (n♀= 16, n♂=16) değerlendirilmiştir. Bireylerin minimum ve maksimum total boy ve ağırlıkları sırasıyla 17,6 - 27,7 cm ve 46,6 - 231,0 g aralığındadır. Farklı vücut bölgelerindeki pullar dişi ve erkek bireyler için ayrı ayrı değerlendirilmiştir. Pul boyutu ve pul şekli gibi morfolojik özellikler hem dişi-erkek bireyler hem de incelenen vücut bölgeleri arasında ayırt edici karakterler olarak belirlenmiştir. Diğer morfolojik özellikler (pul merkezinin pozisyonu, sirkuli, radii tipi, pulun rostral ve kaudal kenarı) ise hem dişi-erkek bireylerde hem de belirlenen bölgeler arasında benzer özellikler göstermektedir. M. batrachocephalus bireylerinin vücut bölgelerindeki pullar karşılaştırıldığında, dişi ve erkek bireylerdeki pulların morfometrik değerleri (genişlik, alan ve çevre) arasında 1. bölge, 4. bölge ve 5. bölge için istatistiksel olarak anlamlı farklılıklar tespit edilmiştir (P<0,05). Bu çalışmada, M. batrachocephalus türünün pul morfolojisi ve morfometrisine ait bilgiler ilk defa sunulmuştur. Çalışma sonucunda dişi ve erkek bireylerin bu özellikler bakımından farklılık gösterdiği tespit edilmiştir. Bu sebeple filogenetik çalışmalarda önemli yer tutan pul morfolojisi ve morfometrisinin, M. batrachocephalus türünün hem dişi hem de erkek bireylerinde ayrı ayrı değerlendirilmesinin gerektiği önerilmektedir.
