Thinlip Gray Mullet Otolith Morphology and Structure from Northern Italy

Otolith morphology and composition data for the thinlip gray mullet (Chelon ramada) from the Reno River mouth in northern Italy. The dataset includes biometric parameters, shape descriptors, mineral composition, and organic matrix content analyzed across juveniles, adults, males, and females. It was authored by Francesca De Witt and last updated in April 2026.

Use Cases

• Analyzing ontogenetic shape changes in otoliths based on biometric parameters like length, width, perimeter, and area.
• Investigating sexual dimorphism in fish based on shape descriptors such as circularity, roundness, aspect ratio, and solidity.
• Studying the relationship between otolith structure and acoustic sensitivity based on mineral composition and organic matrix content.
• Comparing growth patterns between juvenile and adult fish based on morphological characteristics.

Strengths

• Data was generated using a multiscale approach including X-ray powder diffraction, Fourier transform infrared spectroscopy, and thermogravimetric analysis.
• Analysis covers three distinct biological groups: not determined, males, and females.
• Dataset is openly available under a CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 1.5 MB file size suggests a relatively small dataset.
