Çipura (Sparus aurata, Linneaus, 1758) Spermasının Kısa Süreli Saklanması ve Spermatolojik Özellikleri ile Ebeveyn İlişkilerinin Araştırılması

Araştırmada İzmir ili Balıklıova beldesinde bulunan bir üretim çiftliğinden temin edilen çipuralardan alınan sperm örnekleri 0°C’de buz içinde muhafaza edildikten sonra her altı saatte bir faz kontrast tip mikroskopta incelenmiştir. Çalışmada sperm muhafaza süreleri, hız, konsantrasyon, meristik karakterler ve sperm hacmi ile ilgili datalar elde edilmiş ve bu sonuçlar ebeveyn ile ilişkilendirilmiştir. Denemelerde kullanılan balıkların ağırlıkları 405-625 g, boyları ise 25-37 cm sperm hacmi 3,1-8,3 ml.kg-1 olarak tespit edilmiştir. En yoğun konsantrasyon 5,35x109 spz.ml-1 ile 2 numaralı denekte, en düşük sperm konsantrasyonu 0,16×109 spz.ml-1 ile 24 numaralı denekte saptanmıştır. Çalışma süresince tüm denek ve zamanlarda baş boyuna endeksli en yüksek hız 35.5 baş boy.sn-1 (210,16 μm.sn-1), en düşük hız 2,6 baş boy.sn-1 (15,39 μm.sn-1) olarak belirlenmiştir. Çalışma toplam 126 saat sürmüştür. En kısa muhafaza süresi 26-50 saat, en uzun muhafaza süresi 126-150 saat olarak tespit edilmiştir.

Short Term Storage of Gilthead Sea Bream (Sparus aurata, Linneaus, 1758) Spermatazoa and Investigation of Spematological Characteristic with Parental Relationships

Sperm samples taken from gilthead sea bream obtained from a production farm located in the province of Balıklıova in İzmir were examined under one phase contrast type microscope every six hours after they were kept in ice at 0°C. Data related to sperm maintenance durations, speed, concentration and sperm volume were obtained in the study and these results were related to the parent. The fish weighed 405-625 g and the sperm volume 25-37 cm was 3.1-8.3 ml.kg-1. The most intense concentration was found in the second experiment with 5.35x109 spz.ml-1 and the lowest sperm concentration in the second test with 0.16×109 spz.ml-1. During the study, the highest head speed index was determined for all subjects and time as 35.5 head height.sn-1 (210.16 μm.sn-1) and the lowest head speed was 2.6 head height.sn-1 (15.39 μm.sn-1). The study lasted a total of 126 hours. The shortest storage period is 26-50 hours and the longest storage period is 126-150 hours.
