Urla-İskele' den toplanan deniz kestanelerinin (Paracentrotus lividus, Arbacia lixula) gonadasomatik indeks değişimi

A. lixula ve P. lividus Akdeniz’de subtidal kıyısal alanlarda birlikte yaşarlar. P. lividus belirgin tadı ve aroması nedeniyle tüketimde tercih edilen türdür. Gonadları sos, krema, çorba ve omlet içinde taze olarak tüketilir. P. lividus ‘un gonad gelişimi Şubat ve Mayıs (% 8.84 ve % 8.97) aylarında maksimum olmuştur. Elde edilen sonuçlara göre yıl boyunca P. lividus’un gonad indeksi (GSI) 2.87±1.02 ve 8.97±0.56 arasında, A. lixula’un gonad indeksi ise 4.28±1.27 and 6.91±0.84 arasında değiştiği tespit edilmiştir. Urla İskele’deki deniz kestanesi populasyonun % 78.52’sini P. lividus, % 21.47’sini de A. lixula türü deniz kestanelerinin oluşturduğu tespit edilmiştir.

Cycles of gonadosomatic index of sea urchins (Paracentrotus lividus, Arbacia lixula) in Urla-İskele

The sea urchins Arbacia lixula and P. lividus are common on shallow subtidal reefs and live together in the Mediterranean. But P. lividus has been favoured by consumers because of its distinctive aroma and good taste. The gonads are eaten fresh in sauces, soups, creams and omelettes. The development of gonads of P. lividus is its maximum in February and May (8.84%-8.97%). Results indicate that gonad index of P. lividus was calculated between 2.87±1.02 and 8.97±0.56. A. lixula gonad index was calculated between 4.28±1.27 and 6.91±0.84 in this study. P. lividus gonad index is maximum in May. A. lixula gonad index is maximum in February. 78.52% P. lividus and 21.47% A. lixula of populatıon were observed in Urla-İskele population.
