Short Term Storage of Gilthead Sea Bream (Sparus aurata, Linneaus, 1758) Spermatazoa and Investigation of Spematological Characteristic with Parental Relationships
2018
Sperm samples taken from gilthead sea bream obtained from a production farm located in the province of Balikliova in Izmir 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.
