ABSTRACT
Marine teleost species of commercial interest are often reported with hyperostosis, an osteological condition that results in bone thickening. Various specimens of Atlantic Spadefish Chaetodipterus faber (n = 86) obtained from artisanal fishermen in Rio de Janeiro, Brazil, were radiographed and assessed to detect the occurrence of hyperostosis across four different size classes. Of the examined individuals, 58.62% displayed signs of hyperostosis, which manifested in eight skeletal regions, notably in the supraoccipital crest, cleithrum and supraneural areas. In the vertebral column, hyperostosis was more frequently observed in haemal spines than in neural spines, predominantly between the sixth and eighth caudal vertebrae. The smallest size class (<200 mm total length) showed a low frequency of hyperostosis at 7.89%. This frequency escalated for larger classes, reaching 94.12% in individuals measuring 200-300 mm in total length and was observed in all individuals exceeding 300 mm. Hyperostosis exhibited an ontogenetic development pattern, where both the occurrence frequencies and the sizes of the affected bones expanded in proportion to the fish size. This is the first description of the hyperostosis pattern of development for the species, an important commercial resource.
