Abstract

In this study, seasonal disc diameter-weight
relationship of moon jellyfish (Aurelia
aurita) were determined in the Black Sea coasts of Turkey. The samples of
jellyfish were collected monthly from Sinop coasts in the southern Black Sea
between December 2012 and November 2013 with plankton net. A total 1358 moon
jellyfish were measurement in the study. Mean length and weight of all
individuals were established, 8.3±0.10 cm and 43.2±1.58 g respectively. Disc diameter-weight
relationship of moon jellyfish were calculated as Ww=0.1207L^2.5887
for general, Ww=0.1251L^2.5567
for autumn, Ww=0.0815L^2.7181 for winter, Ww=0.1012
L^2.6813 for spring and Ww=0.1289L^2.6844 for
summer. The results showed that “a” and “b” value of moon jellyfish varied
with seasons in the Black Sea coasts.

Türkiye’nin Karadeniz Kıyılarındaki Ay Denizanası (Aurelia aurita)’nın Çap-Ağırlık İlişkisinin Mevsimsel Olarak Belirlenmesi

Abstract

Bu araştırmada Türkiye’nin Karadeniz kıyılarındaki ay
denizanası (Aurelia aurita)’nın
mevsimsel olarak çap-ağırlık ilişkileri belirlenmiştir. Denizanası örnekleri aylık
olarak Aralık 2012-Kasım 2013 tarihleri arasında Güney Karadeniz’in Sinop
kıyılarından plankton ağı ile toplanmıştır. Çalışmada 1358 adet denizanasının
çap ve ağırlığı ölçülmüştür. Tüm denizanaları için ortama boy ve ağırlıkları
8.3±0.10 cm ve 43.2±1.58 g olarak tespit edilmiştir. Denizanalarının çap-ağırlık
ilişikleri tümü için W_w=0.1207L^2.5887, sonbahar için W_w=0.1251L^2.5567, kış
için W_w=0.0815L^2.718, ilkbahar için W_w=0.1012
L^2.6813 ve yaz için W_w=0.1289L^2.6844 olarak
hesaplanmıştır. Bu sonuçlar Karadeniz kıyılarındaki ay denizanasının “a” ve “b”
değerlerinin mevsimsel olarak değiştiğini göstermiştir.
