Hyperostosis in Fishes: An Update With New Species Records
Journal of Morphology, Volume 285, Issue 11, November 2024.Hyperostosis is an enigmatic dimension of diversity in the anatomy of fishes. This excessive overgrowth of bone is natural in origin, occurs almost exclusively in marine fishes, is generally species‐specific, and becomes fully developed only in large individuals. We document hyperostosis in 35 families, 89 genera, and 153 species.

Comparative growth performance of jack mackerels of the genus Trachurus with emphasis on T. symmetricus murphyi in Chile [PDF]
Naga, 1994 This contribution presents von Bertalanffy growth parameter estimates for species/stocks of jack mackerels of the genus Trachurus from around the world, and compares them with growth parameters for T. symmetricus murphyi caught off central-Chile (33 super(o)S-39 super(o)S).
