| Abstract Although several studies on the ichthyofauna of the Fernando de Noronha Archipelago have been carried out, its mesophotic fish diversity has never been surveyed before. Here we used SCUBA and technical rebreather diving, baited remote underwater videos and remotely operated vehicle to record shallow (≤ 30 m depth) and mesophotic (31 to 150 m depth) fishes. Nineteen fish species belonging to 14 families are reported here as new records, representing an increase of 8.2% in marine fish richness for the region, which now has a total of 250 species and 77 families. These new records include four potential new species and highlight the importance of surveying mesophotic ecosystems, even in well studied sites. Our results also emphasize the need for... |

| Muscular tissue from wild-caught mullet (Mugil spp.) and snook (Centropomus spp.) was analyzed by atomic absorption spectrometry to determine muscle contamination levels for cadmium, chromium, copper, lead and zinc and evaluate risks to human health associated with seafood consumption. Fishes were captured by subsistence fishermen in Vitória Bay, a Brazilian tropical estuary with numerous outfalls of untreated industrial and residential sewage. Based on the premisses that subsistence fisherman and local consumer show weak (culinary or other) preferences within the taxa studied, analyses were conducted and results are reported for genera. Snook cadmium, chromium, copper and zinc concentrations were positively correlated with size or weight. Mullet chromium... |
