Occurrence of an abnormal one-eyed black anglerfish Lophius budegassa (Spinola, 1807) from Central Aegean Sea, Turkey

During the seasonal trawling studies between September 2017 and August 2018, one specimen of the Lophius budegassa (Spinola, 1807) was found as one-eyed. This is the first record of this type, morphological abnormality of this fish species from Aegean Sea. Abnormality could be caused by environmental or genetic factors. The other reason might be a one-eyed specimen could be attacked by other carnivores when specimens at early stages. However, based on morphological investigations there were no visible assault scar or wound lesion were found on orbital skin tissue.

Orta Ege Denizi, Türkiye’de anormal tek gözlü fener balığı Lophius budegassa (Spinola, 1807)’nın bulunuşu

Eylül 2017 – Ağustos 2018 tarihleri arasında gerçekleşen mevsimsel trol örneklemeleri sırasında bir adet Lophius budegassa (Spinola, 1807) bireyi tek gözlü olarak bulunmuştur. Bu tip bir bildiri Akdeniz’de morfolojik anormallik olarak bu tür için bir ilktir. Anormallik faktörü çevre ve genetik kaynaklı olabileceği gibi diğer bir sebep olarak, tek gözlü bireyin erken büyüme evrelerinde yırtıcılar tarafindan saldırıya uğramış olduğudur. Ancak morfolojik incelemeler sonucunda orbital deri dokusunda görünür hiçbir yara izi ve yara lezyonu görülmemiştir.
