Özet:

 In this study, the larval development of Cyrtocara moorii was examined morphologically and compared with other Cichlidae species. The important morphological changes and critical developmental stages that C. moorii larvae undergo were determined during the process from hatching up to 20 days. It was observed that the larvae had a large yolk sac, transparent bodies, and undeveloped fins in the first days. Important developmental events such as eye development, mouth opening, onset of free swimming behavior, fin formation, and increased pigmentation were recorded. It was determined that the larvae started free swimming between 6-9 days, the yolk sac was completely depleted on the 10th day, and the larval development was completed, reaching the juvenile form on the 15-20th days. When the larval development of C. moorii was compared with other Cichlidae species, species-specific differences were observed as well as some similarities. It is thought that these differences may be related to the ecological adaptations, reproductive strategies, and evolutionary history of the species. It is suggested that future research should comparatively examine the larval development processes of more Cichlidae species and elucidate the mechanisms underlying this diversity.

 Bu çalışmada, Cyrtocara mooriinin larval gelişimi morfolojik açıdan incelenmiş ve diğer Cichlidae türleriyle karşılaştırılmıştır. Yumurtadan çıkıştan itibaren 20 güne kadar olan süreçte, C. moorii larvalarının geçirdiği önemli morfolojik değişimler ve kritik gelişim aşamaları belirlenmiştir. Larvaların ilk günlerde büyük bir besin kesesine sahip olduğu, vücutlarının şeffaf olduğu ve yüzgeçlerin gelişmemiş olduğu gözlemlenmiştir. Gözlerin gelişimi, ağzın açılması, serbest yüzme davranışının başlaması, yüzgeçlerin oluşumu ve pigmentasyonun artması gibi önemli gelişim olayları kaydedilmiştir. Larvaların 6-9. günler arasında serbest yüzmeye başladığı, 10. günde besin kesesinin tamamen tükendiği ve 15-20. günlerde larval gelişimin tamamlanarak jüvenil forma ulaşıldığı belirlenmiştir. C. mooriinin larval gelişimi, diğer Cichlidae türleriyle karşılaştırıldığında, bazı benzerliklerin yanı sıra türe özgü farklılıklar da gözlemlenmiştir. Bu farklılıkların, türlerin ekolojik adaptasyonları, üreme stratejileri ve evrimsel geçmişleriyle ilişkili olabileceği düşünülmektedir. Gelecekteki araştırmaların, daha fazla Cichlidae türünün larval gelişim süreçlerini karşılaştırmalı olarak incelemesi ve bu çeşitliliğin altında yatan mekanizmaları aydınlatması önerilmektedir.
