“…Excessive bone deposition in fish has earlier been termed calluses (Fjelldal et al, 2004), hyperostosis (Gauldie & Czochanska, 1990;Jawad, 2013;Jawad, Wallace, & Dyck, 2015;Smith-Vaniz, Kaufman, & Glowacki, 1995), and osteomas (Lima, Souza, Mesquita, Souza, & Chinelli, 2002), and probably reflects a variety of pathological and un-pathological conditions. The presently observed 33% deformity rate, and occurrence of severely deformed adult fish, shows that more studies on vertebral column deformities in natural populations are needed in order to assess the magnitude and possible location/species/live stage dependent patterns.…”

“…The distinct appearance of the strip may indicate that a fracture has induced the hyperostosis, and that the excessive bone deposition may be a mechanism to stabilize the haemal spine, or a stage in a fracture repair mechanism, involving callus formation and remodelling into normal morphology (discussed in Fjelldal et al., ). Excessive bone deposition in fish has earlier been termed calluses (Fjelldal et al., ), hyperostosis (Gauldie & Czochanska, ; Jawad, ; Jawad, Wallace, & Dyck, ; Smith‐Vaniz, Kaufman, & Glowacki, ), and osteomas (Lima, Souza, Mesquita, Souza, & Chinelli, ), and probably reflects a variety of pathological and un‐pathological conditions.…”

This study describes radiological malformations in the vertebral column of adult sexually mature wild haddock, Melanogrammus aeglefinus collected from Masfjorden, Western Norway, in 2014 and 2015. There were seven deformed fish (33% of sampled fish), five with mild deformities and two with severe deformities. The deformity types discovered were lordosis, vertebra body asymmetry, compression, fusion (ankylosis), remodelling, and haemal spine hyperostosis. The two severely deformed fish were as follows: (a) one specimen with 29 deformed vertebrae within the region vertebrae nos. 1–30, including two sites of lordosis; (b) one specimen with 15 deformed vertebrae within the region vertebrae nos. 31–52 (most caudal vertebrae). The results of this study show that wild haddock can survive severe vertebra deformities, both in the trunk and tail region, and reach adulthood and sexual maturity. Whether normal nondeformed wild conspecifics would mate and spawn with these individuals and thereby complete the life cycle of the deformed individuals is, however, unknown. A possible link between bone fracture and fish hyperostosis is discussed.

“…For a long time, hyperostosis was considered as an osteoma, a benign bone neoplasm. Among Trichiuridae, the presence of osteomas in Trichiurus lepturus has been reported previously (Lima et al 2002). Osteomas, which are macroscopically nearly identical to hyperostosis, have been observed in T. lepturus particularly on the haemal and neural spines.…”

Occurrence of Hyperostotic Pterygiophores in the Silver Scabbardfish, <I>Lepidopus Caudatus</I> (Actinopterygii: Perciformes: Trichiuridae)

. 2012. Occurrence of hyperostotic pterygiophores in the silver scabbardfish, Lepidopus caudatus (Actinopterygii: Perciformes: Trichiuridae). Acta Ichthyol. Piscat. 42 (3): 233-237.Background. Hyperostosis is a productive change characterized by an increase of the periosteal ossification combined with resorption of the bony tissue. It is common in several fish species. Its presence has been reported in the silver scabbardfish, Lepidopus caudatus (Euphrasen, 1788). The aim of the presently reported study is to improve the knowledge on the presence of hyperostotic pterygiophores in L. caudatus. Materials and methods. In total, 50 specimens of Lepidopus caudatus, captured off the coast of Messina (Sicily, Italy) were examined by radiography. Deformed pterygiophores were decalcified and processed for histopathological examination, and the sections obtained were stained with haematoxylin and eosin. Results. Forty (80%) of the 50 specimens examined showed skeletal deformities exclusively on the pterygiophores of the dorsal fin. In total, 433 deformities were observed. Histological examination showed slight expansion of the bone tissue, which was poor in cells and characterised by thin layers of compact bone tissue. Macroscopic, radiographic, and histological findings were consistent with diagnosis of hyperostosis. Conclusion. Hyperostosis of L. caudatus does not affect its consumption. However, it may be a complication for filleting techniques as the presence of hyperostosis along the longitudinal axis of teleosts does not allow a complete and repeatable filleting technique. This could increase the possibility of bacterial contamination, loss of muscle tissue, and imperfections in cutting and trimming.

“…Osteomas have been noted to affect the vertebral column of cutlass fish, Trichiuris lepturus L., in Brazil; however, these tumours tended to involve the neural and haemal spines of the vertebra rather than the vertebral bodies themselves (Lima, Souza, Mesquita, Souza & Chinelli 2002) . No mention was made as to whether these tumours actually caused lesions, such as scoliosis or lordosis.…”

From mid-2004 to mid-2005, several grass carp, Ctenophayngodon idella (Valenciennes), showing evidence of spinal deformity were presented to the Aquatic Animal Health Program, Cornell University. The carp were from three separate locations in New York State. The first case involved several fish from a natural body of water in the Catskill Mountain region of south-eastern New York State. The second was a single affected individual from a private pond in the Fingerlakes region of Central New York State. The third was a single individual from the Cold Springs Harbor Fish Hatchery, Cold Springs Harbor, Long Island. All fish were at least 7 years of age. Radiographs and computed tomography (CT) scans revealed the deformities to be of bony origin. The spinal deformities were characterized by variable amounts of kyphosis, scoliosis and rotation. While it is not possible to determine the specific cause(s) of the lesions, we consider a genetic component as a likely contributor to the observed pathology.
