An overview on elasmobranch release as a bycatch mitigation strategy Natascha Wosnick, Eloísa Pinheiro Giareta, Renata Daldin Leite, Ingrid Hyrycena, Patricia Charvet ABSTRACT: Sharks and rays are among the most threatened vertebrates, mostly due to commercial fisheries. Data on incidental capture is sparse, but it is estimated that about 50% of reported global catches of

Genital mycobacteriosis caused by Mycobacterium marinum detected in two captive sharks by peptide nucleic acid–fluorescence in situ hybridization Mari Inohana, Takeshi Komine, Yoshiaki Tanaka, Osamu Kurata, Shinpei Wada ABSTRACT: Mycobacterium marinum is a prevalent nontuberculous mycobacterium (NTM)-infecting teleosts. Conversely, little is known about mycobacteriosis in elasmobranchs, and M. marinum infection has never been reported from the

Bioapatite in shark centra studied by wide-angle and by small-angle X-ray scattering J. S. Park, J. D. Almer, K. C. James, L. J. Natanson, S. R. Stock ABSTRACT: Members of subclass Elasmobranchii possess cartilage skeletons; the centra of many species are mineralized with a bioapatite, but virtually nothing is known about the mineral’s organization. This

New shark species added to Bermuda’s fish fauna

A new species of shark, the Ragged-tooth shark (also known as the Small tooth sand tiger and, scientifically, as Odontaspis ferox), has now been officially added to list of fishes found in Bermuda waters. As often happens, the first encounter with this species was at the end of a fishing line. A commercial fishing vessel,
