Abstract

Osteological development of jaw in cultured european seabass (Dicentrarchus labrax L. 1758) larvae. The development of the jaw, where is in oral cavity, in European seabass, Dicentrarchus labrax, (L. 1758), larvae was examined from 1 to 42 days post-hatching during the early ontogeny under well-defined intensive environmental culture conditions. During the study, specimens were examined on per 3 days until the end of weaning. Preparation techniques included fixation in formalin, trypsin clearing and staining with alcian blue and alizarin red S. At hatching, D. labrax were devoid of any cephalic elements in oral cavity. At 3.8 mm total length (TL), Meckel’s cartilage appeared first. At 4.6 mm TL, the trabecular bars, palato-quadrate and the ethmoid plate showed. At 5.4 mm TL, hyoid bar, maxillary, basibranchial and branchial basket constituted the bottom of the oral cavity. At 7.9 mm TL, the first signs of dentaries were presented as the premaxillary. At 11.4 mm TL, there were no sign of ossification on the premaxillary and the dentary. At 15.8 mm TL, tip of the premaxillary and the dentary were start of ossification while the cartilaginous structures continue to regress. The development pattern of jaw in oral cavity found in D. labrax is quite similar to that described for other Sparid species.

Özet

Levrek larvalarında 0-42. günler arasında yoğun yetiştiricilik koşulları altında ağız boşluğunda çeneye ait elementlerin kıkırdak ve kemik gelişimleri incelenmiştir. Örnekler çalışma boyunca üç günde bir olacak şekilde elde edilmiş ve çalışma canlı yeminkesilmesi ile sonlanmıştır. Elde edilen örnekler formalinde sabitlendikten sonra alcian mavisi ve alizarin kırmızısı ile boyandı. Yumurtadan çıkan larvada ağza ait bir osteolojik oluşum tespit edilmemiştir. İlk oluşan element 3,8 mm total boyda (TB) Meckel’s kıkırdağıdır. Bu oluşumu 4,6 mm TB’da trabecular bar, palato-quadrate ve hyosymplectic takip eder. 5,4 mm TB’da basibranchial, hyoid bar, maksillary ve branchial sepet oral boşluğun altında meydana gelmiştir. 7,9 mm TB’da dişe ait yapıların ilk işareti olan premaksillary oluşumu gözlenmiştir. 11,4 mm TB’da premaksillary ve dentary kıkırdak yapıda olup henüz kemikleşme başlamamış olup her ikisinde de bir sıra diş tespit edilmiştir. 15,8 mm TB’da premaksillary ve dentarynin uç bölgelerinde kemikleşme başlamıştır. Bu çalışmadan elde edilen sonuçlar diğer teleostlar ile karşılaştırılmış ve benzer bulgulara rastlanmıştır.
