Ege Denizi’nde Dağılım Gösteren Echelus myrus (Linnaeus, 1758) Türünün Üreme Özelliklerinin Belirlenmesi

Çalışmada Ildır Körfezi, Çeşme (Ege Denizi)’nin üç farklı bölgesinden Mart-Nisan 2018 tarihlerinde ticari trol teknesi ile elde edilen Echelus myrus (Linnaeus, 1758) bireylerinin üreme özellikleri incelenmiştir. Örneklerde boy ve ağırlık değerleri sırasıyla; 55,5-97,0 (70,63±12,85) cm, 180,84-420,83 (276,50±70,50) g’dır. Boy-ağırlık ilişkisi W=0.2936L1.61 (R2=0,96)’dir. Fekondite; 25563-55016 (41811±9416) oosit olarak tespit edilmiş olup total boy-fekondite arasında F=658.54L-5603.9 (R2=0,86) şeklinde doğrusal bir ilişki saptanmıştır. Oosit çapları; 0,84-1,09 mm (0,95±0,06) olarak tespit edilmiştir.

Determination of reproductive characteristics of Echelus myrus (Linnaeus, 1758) from the Aegean Sea

The present study which determined the reproduction characteristics of the painted eel Echelus myrus (Linnaeus, 1758) obtained by commercial trawlers from three different regions of Ildır Bay, Çeşme (Aegean Sea) was carried out March-April 2018. The total length-weight values were 55.5-97.0 (70.63±12.85) cm, 180.84-420.83 (276.50±70.50), respectively, and total length-weight relationship was computed as W=0.2936L1.61 (R2=0.96). Fecundity was computed as 25563-55016 (41811±9416) oocyte and a linear relationship between fecundity and total length was calculated as F=658.54L-5603.9 (R2=0.86). Oocyte diameterswere determined 0.84-1.09 mm (0.95±0.06).
