ARANZAZU TABORDA, Diego A; RODRIGUEZ, Berardo de J  y  DUQUE AGUDELO, Biviana A. Endocrine disruption in fish. Rev Colom Cienc Pecua [online]. 2012, vol.25, n.2, pp.312-323. ISSN 0120-0690.

The exposure of living creatures to endocrine disruptors is universal, as they are scattered throughout the world as a result of its widespread use. The variety of endocrine disruptors is very broad and growing every day, including chemicals synthesized by humans, additionally to substances found naturally in the environment. The endocrine disruptors constitute a threat not only to animal health and reproduction, but possibly to humans as well. Biomarkers are used as risk indicators for endocrine disruption. Considered amongst them are plasma steroids levels, induction of vitellogenin and zone radiate protein, and, histology and immunohistochemistry of the liver, gonads and other organs. The appropriate and combined use of biomarkers has allowed significant advances to understand fish reproductive toxicology in both field and laboratory studies. Given that few reports have been published in Colombia on this area, and considering its global importance, this article scrutinizes the state of the art on problems caused by the DE and points out the need of doing more research on this issue.

Palabras clave : ecotoxicology; estrogens; fish; vitellogenin.
