Osteocranium Anatomy of African Catfish (Clarias gariepinus Burchell 1822) from Cultured Pond in Aceh, Indonesia
AbstractTo date, information related the skeletal morphology of fish in Indonesia is still limited. Therefore, we firstly described the morphology of the cranium of African catfish (Clarias gariepinus) collected from aquaculture pond in Aceh Province, Indonesia. In the present study, research methodology included the preparation of cranium, photographing, editing images and identifying the terminology of cranium. The cranium was prepared physically and chemically. Each part of the cranium was documented using a Canon EOS 700D camera and edited using Adobe Photoshop CS6. The cranium nomenclature was determined by comparing the similarity of the shape and location of each part of the fish cranium that has been studied previously. The cranium of African catfish was divided into two major parts, namely neurocranium (ossa neurocranii) and splanchnocranium (ossa splanchnocranii). Neurocranium had four regions belonging to etmoidal, orbital, otic and occipital, while splanchnocranium had five regions belonging to maxillaris, mandibularis, arcus mandibularis, arcus hyoideus, and apparatus operculare. The African catfish had a strong and thick neurocranium structure. However, orbital, arcus hyoideus and apparatus operculare regions were not well developed. The results of this study could be used as a basic for further research, especially in the field of taxonomy and phylogeny of fish.
- We first described the anatomy of the cranium of African catfish (Clarias gariepinus) collected from a cultured pond in Aceh Province, Indonesia.
- The African catfish neurocranium is divided into four regions: ethmoidal, orbital, oticum, and occipital regions, while the splanchnocranium is divided into five regions, namely the maxillary, mandibular, arcus mandibular, arcus hyoideus, and opercular apparatus.
- The African catfish has a solid and thick neurocranium structure. However, orbital, arcus hyoideus, and apparatus opercular regions are not well developed.
