Çeşme Körfezi'ndeki (Doğu Ege Denizi) Avrupa Deniz Kestanesi'nin (Paracentrotus lividus, Lamarck, 1816) gonad ve mide indeksleri

Bu çalışmanın amacı Ege Denizi kıyılarında bulunan Paracentrotus lividus populasyonunun mide ve gonad verimini belirlemek ve gonad indeks değişimi üzerine çevresel koşulların etkisini değerlendirmektir. Bunu gerçekleştirmek içinde, oniki ay boyunca örnekler toplandı ve biyometrik ölçümler yapıldı. Kasım ve Mayıs ayları arasında su sıcaklığı çok fazla değişmemesine rağmen yaş gonad indeksi en soğuk aylardan biri olan Nisan ayında (14°C) pik (6.22±0.56 %) yaptı. Bu çalışmada, su sıcaklığının düşmesi gonad üretimini etkilediği fakat gonadı etkileyenin sadece sıcaklık olmadığı çünkü diğer soğuk aylar boyunca gonad indeksinin yüksek olmadığı belirlendi. Mide indeksi (GII) Ocak (% 6.31±0.71) ve Mayıs (% 6.07±0.70) ayları arasında daha yüksekti. Bu çalışmada mide indeksi ilkbaharda sonbahara gore daha yüksekti.

Gonad and gut indices of European Sea Urchin (Paracentrotus lividus, L, 1816) in Çesme Bay of Eastern Agean Sea

The objective of present study is to determine the gut and gonad yield of Paracentrotus lividus populations occuring along Aegean Sea coastline and to evaluate of the environmental conditions on the gonad indices variability. To achieve this, samples were gathered during twelve months and biometric measurements were done. The wet gonad index peaked (6.22±0.56 %) in one (April-14°C) of the coldest months (between November-May) even though water temperature was not change so much between November and May. It is determined that decreasing temperature affected gonad production but temperature is not only one factor effecting of gonad because of gonad indices were not high during the other cold months (between November-May) in this study. The higher gut index (GII) values were observed between January (6.31±0.71 %) and May (6.07±0.70 %). The gut index was higher in spring than in fall in this study.
