Bu araştırmada Çoğun Baraj Gölü’nde yaşayan Cyprinus carpio’nun en güvenilir kalsifiye yapısı belirlenmiştir. Yaş tayini amacı ile pul, omur, asteriskus, lapillus, operkül ve suboperkküller alınmıştır. Güvenilir kalsifiye oluşumu tespit etmek amacı ile yüzde uyum (YU), ortalama yüzde hata (OYH) ve değişim katsayısı (DK) hesabı yapılmıştır. Tekrarlı okumalar neticesinde tüm yapılarda 4 yıl sınıfı elde edilmiş olup en baskın yaş grubunun 5 yaş olduğu belirlenmiştir. Analiz sonuçlarına göre en yüksek yüzde uyum asteriskusta (%76.8) tespit edilirken en düşük yüzde uyum ise suboperkülde (%31.0) saptanmıştır. OYH ve DK değerleri en düşük asteriskusta (OYH= 2.79, DK= 3.94) tespit edilmiştir. Sonuç olarak türün yaş tayini için güvenilir kalsifiye yapı asteriskus olarak belirlenmiştir.
This study identified the most reliable calcium structure of Cyprinus carpio living in the Most Barage Lake. For the purpose of age determination, pul, spine, asteriskus, lapillus, operculus and suboperculus were taken. To identify the formation of reliable calcium, the percentage of conformity (YU), the average percentage of error (OYH) and the exchange rate (DK) were calculated. Repeated readings have found that all structures have a four-year class and that the most dominant age group is 5 years old. According to the results of the analysis, the highest percentage of harmony was detected in asteriskus (76.8%) while the lowest percentage of harmony was detected in suboperkula (31.0%). The OYH and DK values have been found at the lowest asterisk (OYH = 2.79, DK = 3.94) As a result, a reliable calcium structure for the age determination of the species has been determined as asteriskus.
In this study, the most reliable calcified structure of Cyprinus carpio living in Çoğun Dam Lake was determined. Scales, vertebra, asteriscus, lapillus, operculum and subopercules were taken for age determination. Percentage of agreement (PA), average percentage of error (APE) and coefficient of variation (CV) were calculated in order to determine reliable calcified formation. As a result of repeated readings, 4-year class was obtained for all calcified structures and it was determined that the most dominant age group was 5 years. According to the results of the analysis, the highest PA was detected in the asteriscus (76.8%), while the lowest PA was found in the subopercule (31.0%). The lowest APE and CV values were determined in asteriscus (APE = 2.79, CV = 3.94). As a result, the reliable calcified structure for age determination of the species was determined as asteriscus.
