Morphometric dataset of Mugil incilis from three estuarine systems in the Colombian Caribbean

This dataset includes morphometric measurements and metadata for 196 Mugil incilis specimens collected from three estuarine systems—Ciénaga Grande de Santa Marta, Ciénaga de la Virgen, and Ciénaga La Caimanera—in the Colombian Caribbean. It features inter-landmark distances used in truss network analysis, total and eviscerated weights, and biological descriptors such as sex and gonadal stage. The data support a stock identification analysis using multivariate statistical models.
