Baseline levels of biomarkers of oxidative damage in Odontesthes nigricans (Pisces, Atherinopsidae) from two coastal areas of the Beagle Channel, Argentina

We assessed several biomarkers of oxidative damage on silversides Odontesthes nigricans from Varela and Golondrina bays, located on the North shore of the Beagle Channel (Tierra del Fuego, Argentina) and we tried to relate those responses to environmental data. Varela bay is visited mostly by local...
