Respostas histopatológicas hepáticas de Sphoeroides testudineus em áreas costeiras sob diferentes níveis de pressão antrópica

Hepatic histopathology was used to compare Sphoeroides testudineus from the Barra do Una Sustainable Development Reserve, a reference area, and the Port of Santos channel. The histopathological index was higher in Santos (48.0 ± 6.9) than in Barra do Una (28.7 ± 8.5; p<0.001), with more melanomacrophage centers and leukocyte infiltration. The hepatosomatic index (p=0.479) and Le Cren condition factor (p=0.939) did not differ. Results indicate greater hepatic impairment in Santos but do not support attribution to a specific contaminant.
