Abstract

The present study which determined the reproduction characteristics and fecundity of the round sardinella Sardinella aurita Valenciennes, 1847 in the Aegean Sea was carried out between October 2010 and September 2011. In total 358 individuals were collected, from which 159 (44.4%) were males and 199 (55.6%) males. Female-male ratio was determined of 1.25:1. According to gonadosomatic index spawning season was observed May and July. Total fecundity ranges from 66.608 to 85.805 oocytes (mean: 72.057±5037.5), total length-fecundity relationship is F= 1309.3L1.275 (r2=0.82). Diameter of oocyte is 0.32-0.74 mm (mean 0.62±0.08).

Özet

Bu araştırmada Ekim 2010 – Eylül 2011 periyodunda Ege Denizi’nde ticari gırgır tekneleri ile avcılık yapan balıkçılardan elde edilen büyük sardalya balığının Sardinella aurita Valenciennes, 1847 yumurta verimliliği belirlenerek üreme özellikleri çalışılmıştır. Cinsiyeti belirlenen 358 adet bireyin 159 adedi erkek (%44,4), 199 adedi ise dişi (%55,6) olarak tespit edilmiştir. Dişi erkek oranı 1,25:1 olarak saptanmıştır. Türün hesaplanan gonadosomatik indeks değerine göre üreme mevsimi Mayıs ve Temmuz ayları arasındadır. Toplam fekondite 66,608-85,805 (ortalama: 72,057±5037,5) oosit, total boy-fekondite ilişkisi F= 1309,3L1,275 olarak belirlenmiştir (r2=0,82). Oosit çapı; 0,32-0,74 mm (ortalama 0,62±0,08)’dir.
