İnek burunlu vatoz, Rhinoptera bonasus, balığı popülasyonu son 43 yıl içerisinde aşırı ve bilinçsiz avcılık nedeniyle %30-49 oranında azalmış ve IUCN Kırmızı Listesi tarafından nesli tükenme tehlikesi altındaki balıklar listesine dahil edilmiştir. Bu çalışmada dorsoventral olarak basık bir vücut şekline sahip inek burunlu vatoz balıklarının eksternal ve internal anatomik incelemelerin yapılabilmesi amacıyla spesifik bir diseksiyon tekniği sunulmuştur. Balıklar, doğal ölüm sonrası bir şehir akvaryumundan laboratuvara taşınmış ve chondrocranium, solungaçlar, perikardiyal boşluk ve pleuroperitoneal boşluğun açılması amacıyla dört ana kesi alanı ile diseke edilmiştir. Balığın dorsal yüzeyi pürüzsüz, yeşilimsi-kahverengi renkli, ventral karın yüzeyi ise beyazdır. Karaciğer pleuroperitoneal boşluğun büyük kısmını doldurmakta ve özefagus, mide, duodenum, valvüler bağırsak, dalak, böbrek ve uterusu örtmektedir. Valvüler bağırsak veya spiral valf, sindirim sisteminin en büyük organlarından birini oluşturmaktadır. Çoğu inek burunlu vatozda sadece sol ovaryum gelişmiş ve işlevseldir; bu nedenle balıkların ovaryumları median hattın solunda, pleuroperitoneal boşluğun kraniyal ucuna yakın ve midenin kaudalinde yer alır. Sonuç olarak, sunulan diseksiyon teknikleri, inek burunlu vatozların eksternal ve internal anatomisinin incelenmesine olanak sağlayacak ve iç organlara uygun bir yaklaşıma katkıda bulunacaktır.

Macroscopic Examination of Cownose Rays (Rhinoptera bonasus)

The cownose ray, Rhinoptera bonasus, is currently listed as vulnerable and threatened species by the IUCN Red List due to overfishing and bycatch in worldwide resulted declines of the steep population declines of 30-49% in only 43 years. We aimed to present suitable dissection methods for a necropsy of cownose ray with a large, rhomboid-shaped wing-like pectoral disc and compressed dorsoventrally using a specific approach to observe external and internal anatomy. The fish were obtained from a public aquarium after natural death and were dissected with four incision area to open chondrocranium, gills, pericardial cavity and pleuroperitoneal cavity. The dorsal surface of the body is completely naked and smooth, greenish-brown colored, in contrast the ventral surface of the body is white. The liver fills most of the pleuroperitoneal cavity and covers the esophagus, stomach, duodenum, valvular intestine, spleen, kidney and uterus. The valvular intestine or spiral valve is one of the largest organs of the digestive system. In most rays, only the left ovary is developed and functional; therefore, the ovaries of the specimens are located on the left to the median line, close to the cranial end of the pleuroperitoneal cavity, and caudal to the stomach. In conclusion, the presented dissection techniques will enable to examine of the external and internal anatomy of cownose rays and will contribute to a suitable approach to organs.
