Abstract

This study was carried out to determine the ultrasonographic imagine techniques of the reproductive tracts and egg development of the sea turtles (Chelonia mydas and Caretta caretta) which are nesting in East Mediterranean coasts of Turkey. Research material consisted of 8 female C. mydas and 3 female C. caretta sea turtles. The study was carried out from february to july. Ultrasonographic examinations were performed in marine and coastal environment with a B mode real time ultrasonography and 5.0-7.5 MHz micro-convex probe. Probe was placed in left and right inguinal apertures parallel to plastron in different angels for screening the reproductive organs and egg development. Vesica urinaria, ovaries, oviducts (when filled with eggs) developing follicles in different stages and eggs with or without shell (before laying) were screened. Detailed examinations were performed in reproductive organs, developing follicles and eggs. Diameter of the egg’s, egg’s albumin and vitellus were measured. Fertilized eggs, in prenesting sea turtles were also screened. In C. mydas sea turtles at the beginning of the nesting season; egg diameter, vitellus diameter and albumin width in shelled eggs measures were determined as 3.72±0.2, 2.55±0.128 and 0.62±0.098 cm respectively. The same measures in the mid-nesting season were 3.96±0.166, 2.64±0.155 and 0.678±0.079 cm respectively. Vitellus diameters in eggs without shell at the beginning of the nesting season, mid-nesting season and at the end of nesting season were 2.26, 2.1 and 2.93±0.07 cm respectively. Germinal disc width at the beginning of the nesting season, mid-nesting season and at the end of nesting season were 0.69, 0.77±0.1 and 0.85±0.26 cm respectively. Vertical diameters of the ovary in mid-nesting season and at the end of the nesting season were 5.8 and 5.35±0.63 cm respectively. Diameters of the oviduct in mid-nesting season and at the end of nesting season were 6.8 and 5.25±0.49 cm respectively. It was concluded that, ultrasonographic examinations with a 5.0-7.5 MHz microconvex probe was an easy imaging technique in the screening of reproductive organs, follicle development and eggs in the sea turtles without using sedative or anesthetic medications without giving any extra stress in marine and coastal environment.

Özet

Çalışma, Doğu Akdeniz sahillerinde yuvalayan deniz kaplumbağalarının (Chelonia mydas ve Caretta caretta) üreme organları ve yumurta gelişimlerinin ultrasonografik görüntüleme tekniklerinin ve bu yapılara ait ölçülerin ortaya konması amacıyla düzenlendi. Çalışma materyalini 8 dişi Chelonia mydas ve 3 dişi Caretta caretta deniz kaplumbağası oluşturdu. Çalışma şubat ayının başı ile temmuz ayının sonu arasında yürütüldü. Çalışma, 5.0-7.5 MHz mikrokonveks problu B mode ultrasonografi cihazı kullanılarak deniz ortamında ve karasal ortamda yürütüldü. Üreme organları ve yumurta gelişiminin görüntülenmesi, sağ ve sol inguinal açıklıktan, ultrason probunun plastrona paralel olarak yerleştirilmesinden sonra farklı açılar denenerek yapıldı. Çalışmada, (idrarla dolu iken) idrar kesesi, ovaryumlar, yumurta içeriyorken oviduktlar, gelişimlerinin farklı aşamalarındaki folliküller, kabuklu ve kabuksuz yumurtalarla yuvalama için sahile çıkan kaplumbağalarda fertilize yumurtalar görüntülendi. Kaydedilen görüntülerden yumurta, yumurta albumini ve vitellus çaplarının ölçümleri detaylı olarak yapıldı. C. mydas için üreme mevsimi başında kabuklanmış yumurtalarda: yumurta çapı, vitellus çapı ve albumin genişliği sırayla 3.72±0.2, 2.55±0.128 ve 0.62±0.098 cm olarak belirlendi. Aynı ölçüler üreme mevsimi ortasında 3.96±0.166, 2.64±0.155 ve 0.678±0.079 cm olarak alındı. Kabuklanmamış yumurtalardaki vitellus çapı üreme mevsimi başı, ortası ve sonunda sırayla 2.26, 2.1 ve 2.93±0.07 cm olarak belirlendi. Germinal disk genişliği üreme mevsimi başı, ortası ve sonunda 0.69, 0.77±0.1 ve 0.85±0.26 cm olarak belirlendi. Ovaryumun vertikal çapı ve oviduktun çapı üreme mevsimi ortasında 5.8 ve 6.8 cm, üreme mevsimi sonunda ise sırayla; 5.35±0.63 ve 5.25±0.49 cm olarak belirlendi. Sonuç olarak; ultrasonografi ile 5.0-7.5 MHz mikrokonveks prob kullanılarak, deniz kaplumbağalarında üreme organları ve yumurta gelişiminin, deniz ya da karasal ortamda herhangi bir sedatif ya da anestezik madde kullanmadan ve kaplumbağada ekstra stres oluşturmadan izlenebileceği kanaatine varıldı.
