Abstract

Seasonal growth and reproduction biology of the blue crab, Callinectes sapidus were studied in the Beymelek lagoon, southwestern coast of Turkey between July 2009 and September 2010. The seasonal von Bertalanffy growth parameters were obtained by Hoenig method using the LFDA (Length Frequency Distribution Analysis) for each sex. The LFDA analyses showed that male crabs had higher L∞ and lower K and higher Φ' values (L∞ =230.1 mm, K=0.860 year) than females (L∞ =181.9 mm, K=1.064 year). Seasonal variation of growth for females (C=0.93) were found stronger than males (C=0.29). The slowest growth period started in October (WP=0.79) for females and in January (WP=0.06) for males. Ovigerous females were appeared in the population in February and peaked in August and September. The spawning period of C. sapidus was between July and September. The length of maturity of 50% was estimated as 118.5 mm length for females.

Abstract

Türkiye’nin Güneybatı kıyısında yer alan Beymelek Lagün Gölündeki mavi yengeçlerin Temmuz 2009 ve Eylül 2010 tarihleri arasında mevsimsel büyümesi ve üreme biyolojisi incelenmiştir. Mevsimsel olarak von Bertalanffy Büyüme Parametreleri her bir cinsiyet için LFDA paket programı (Boy Frekans Dağılım Analizleri) kullanılarak Hoenig metodu ile elde edilmiştir. LFDA ile yapılan analizler sonucunda erkek mavi yengeçlerin (L∞ =230,1 mm, K=0,86 yıl) dişilere göre (L∞ =181,9 mm, K=1,064 yıl) yüksek L∞ , düşük K ve yüksek büyüme performansı (Φ') değerine sahip olduğu görülmüştür. Büyümenin dişilerdeki mevsimsel değişiminin (C=0,93) erkeklerden (C=0,29) daha kuvvetli olduğu bulunmuştur. Büyümenin en yavaş olduğu dönem dişilerde Ekim ayında (WP=0,79) erkeklerde ise Ocak ayında (WP=0,06) başlamıştır. Yumurtalı dişiler populasyonda Şubat ayında görünmeye başlamış ve Ağustos ve Eylül aylarında yoğunlaşmıştır. Mavi yengeçler için üreme zamanı Temmuz-Eylül arası olarak belirlenmiştir. Dişiler için %50 olgunluk boyu 118,5 mm karapaks genişliği olarak tespit edilmiştir
