The presence of hyperostosis in Atlantic moonfish, Selene setapinnis (Mitchill, 1815) in the Brazilian Coast ˗ case report

[A presença de hiperostoses no peixe-galo-sem-penacho, Selene setapinnis (Mitchill, 1815) na costa brasileira ˗ relato de caso]

ABSTRACT

The occurrence of hyperostotic bones is common in marine fish, especially in the Carangidae family, despite few records of this condition in fishes from Brazilian waters. The present study describes the occurrence of hyperostosis in Atlantic moonfish (Selene setapinnis) in, Rio de Janeiro State, Brazil. Radiographs of the fish specimens were taken and all of them presented hyperostosis in at least three different regions: cleithrum, pterygiophores and pleural ribs. The observed pattern is different from previously described for other species of the same genus. It is the first record for the species and a valuable contribution to the study of bone diseases in fishes from the Brazilian coast.
