摘要

This study documents skeletal deformities observed in three fish species (Pseudorasbora parva, Pseudophoxinus battalgilae, and Oxynoemacheilus eregliensis) sampled from the Gezende and Ermenek reservoirs in Türkiye. Utilizing high-resolution X-ray technology, we identified and categorized the following anomalies calluses, kyphosis, lordosis, vertebral fusions, malformed pterygiophores in the dorsal fin, bifurcated neural spines on the caudal vertebrae, fractures in the dorsal fin ray pterygiophores, and aberrant abdominal ribs. This study employs high-resolution digital radiography as a core methodological tool. It leverages the fundamental principles of X-ray imaging—differential absorption to create high-contrast images of bone—to achieve its goals. The text effectively argues that this technique is not just useful but is a powerful, essential, and practical method for modern biological research, particularly in fields requiring detailed internal examination without destruction of the specimen.
