Resumen:
Patagonotothen tessellata is one of the most abundant notothenioid fish in the Beagle Channel. Gonads of fish collected from Bahía Ushuaia (Tierra del Fuego, Argentina) accumulate persistent organic pollutants associated with human activity. In addition, feminization of P. tessellata was recently reported, supported by an upregulation of vitellogenin in male fish. The aim of the present work is to assess tissue damage in testes of this species, in order to determine the degree of pollution in Bahía Ushuaia and surrounding areas of the Beagle Channel.
