Abstract

This study examined fecundity, by means of the gonad index of the most common and abundant echinoderm species (Paracentrotus lividus) of the Aegean Sea (western Turkey). Paracentrotus lividus samples were collected monthly at the coast of Cesme for six months and biometric parameters were measured and then the animals’ dissected. Gonad indices were calculated. The mean fecundity (number of eggs) was determined and eggs diameter were measured. Mean egg diameter was 91.14±1.46 µm. There was a peak in fecundity in March (346.582 eggs/female) that correlated with the observed peak in GSI (11.02±0.54 %) and egg size (95.68±01.98 µm). The results presented here show that a significant different was found in egg numbers and egg sizes between months (p<0.05)

Özet

Bu çalışmada, Ege Denizi'nde (Türkiye'nin batısı) yaygın bulunan echinoderm türlerinden Paracentrotus lividus'un fekondite ve gonad indeksi özetlenmiştir. Çeşme kıyısal alandan aylık olarak Paracentrotus lividus toplanarak biyometrik ölçümleri yapıldıktan sonra kesme işlemi gerçekleştirilmiştir. Gonad indeksleri hesaplanmıştır. Ortalama fekondite (yumurta sayısı) belirlendi ve yumurta çapı ölçülmüştür. Ortalama yumurta çapı 91.14±1.46 µm. Fekondite Mart ayında pik yaptı (346.582 eggs/female) ve ilişkili olarak gonad indeksi (11.02±0.54 %) ve yumurta boyu da (95.68±01.98 µm) bu ayda en yüksekti. Buradaki sonuçlar, aylara göre yumurta sayısı ve yumurta boyunda önemli bir farklılık (p<0.05) olduğunu göstermiştir
