Abstract:

 In this study, some biological characteristics of the invasive moon crab, Matuta victor, which has recently entered the waters of the northeastern Mediterranean, Türkiye, were investigated for the first time. The study was carried out seasonally on sandy bottoms at 0.5-3 m depths along Karataş Adana, Türkiye coasts between 2020 -2021. A total of 364 crabs were obtained, 93 females 27 ovigerous, 270 males and one juvenile. The carapace width of female crabs ranged between 27.49-49.30 mm with a mean of 41.554.01 mm. The carapace width of male crabs ranged between 21.28-66.70 mm with a mean of 49.158.97 mm. Mean carapace length measurements in females and males were 26.832.52 mm and 32.715.85 mm, and the mean total weights were 8.181.99 g and 16.277.30 g, respectively. The male:female ratio was 2.16:1. Morphometric relationships indicated negative allometric growth for females, males, and both sexes. Ovigerous females were obtained in all seasons except the winter. The female crabs with carapace widths that ranged between 35.31-48.84 mm and a mean of 41.973.29 mm had a mean fecundity of 36822.0429745.9 eggs.

 Bu çalışmada kuzeydoğu Akdenize son zamanlarda giriş yapmış istilacı Ay Yengeci Matuta victorun bulunurluğu ve bazı biyolojik özellikleri ilk kez incelenmiştir. Çalışma Karataş Adana sahillerinde, 2020-2021 yılları arasında mevsimsel olarak 0,5-3 m derinliklerdeki kumlu zeminde gerçekleştirilmiştir. Çalışmada 93 dişi 27si yumurtalı 270i erkek ve 1 tanesi juvenil olmak üzere toplam 364 birey elde edilmiştir. Dişi bireylerde 27,49-49,30 mm arasında değişen karapas genişliği ortalama 41,554,01 mm olarak hesaplanmıştır. Erkek bireylerde 21,28-66,70 mm aralığında değişen karapas genişliğinin ortalaması 49,158,97 mm olarak ölçülmüştür. Ortalama karapas uzunluk ölçümleri dişilerde ve erkeklerde sırasıyla; 26,832,52 mm ve 32,715,85 mm; ortalama total ağırlıkları ise 8,181,99 g ve 16,277,30 gr bulunmuştur. Erkek:dişi oranı 2,16:1 olarak hesaplanmıştır. Dişi, erkek ve tüm bireylerde hesaplanan morfometrik ilişkiler incelendiğinde negatif allometrik büyüme saptanmıştır. Kış ayları dışında diğer mevsimlerde yumurtalı dişiler elde edilmiştir. Karapas genişlikleri 35,31-48,84 mm ve ortalama 41,973,29 mm olan yumurtalı dişilerin, yumurta verimlilikleri ortalama 36822,0429745,9 yumurta olarak hesaplanmıştır.
