Demirköprü Baraj Gölü'nde (Manisa) yaşayan tatlısu ıstakozunun (Astacus Ieptodactylus Eschscholtz, 1823) bazı üreme özellikleri

Bu çalışmada, Demirköprü Baraj Gölü tatlısu ıstakozunun (Astacus leptodactylus Eschscholtz, 1823) yumurta çapı ve ağırlığı ile verimliliği konusu incelenmiştir. Yumurta taşıyan 92 dişi birey üzerinde yapılan araştırmada ortalama yumurta sayısı yaklaşık 137±7 adet, birim canlı ağırlığa düşen yumurta sayısı 5±0,2 adet, ortalama yumurta çapı 2,72±0,003 mm, ortalama yumurta ağırlığı (tek yumurta) 0,015±0,0002 g olarak belirlenmiştir. Total Boy-Yumurta Sayısı arasındaki ilişki log YS= -6,7999+4,4934 log TB; Total Ağırlık-Yumurta Sayısı arasındaki ilişki ise log YS= -0,1809+1,6145 log TA olarak bulunmuştur. Yumurta sayısının, bireyin total boyundan çok total ağırlığı ile ilişkili olduğu belirlenmiştir. Boyları 72,8-123,9 mm arasında değişen dişilerin yumurta sayıları en az 6, en çok 286 adet olarak belirlenmiştir.
