Abstract

In this study, a shoal of bull rays, Aetomylaeus bovinus (E. Geoffroy Saint-Hilaire, 1817), around a sea-cage fish farm in Iskenderun Bay, Turkey is reported. Such an aggregation is probably due to ontogenetic shift but may also be a factor of reproductive process as some pregnant females were observed. The number of individuals recorded, in all more than 25, shows that the species is still present in the area but needs a conservation plan due to its k-selected life-histories and potential for extinction.

İskenderun Körfezi'nde (Türkiye, Kuzey-Doğu Akdeniz) Balık Çiftliği Etrafında Aetomylaeus bovinus (Myliobatidae) Sürüsünün Varlığı

Abstract

Bu makalede Türkiye sularında İskenderun Körfezi'nden bir balık çiftliği çevresinde Aetomylaeus bovinus (E. Geoffroy Saint-Hilaire, 1817) sürüsü rapor edilmektedir. Bu tür bir toplanma muhtemelen ontogenetik yer değiştirmeden kaynaklanmaktadır; ancak aynı zamanda bu sürüde bazı hamile dişilerin ortaya çıkması nedeniyle üreme sürecinden de kaynaklanmaktadır. 25'ten fazla kaydedilen örnek sayısı, türün bölgede hala mevcut olduğunu, ancak k-seçilmiş yaşam öyküleri nedeniyle olası bir yok oluştan korunmak için bir yönetim planına ihtiyaç duyulduğunu göstermektedir.
