Resumo(s)
An inventory of benthic and benthopelagic fishes is presented as a result of two exploratory surveys
around Ampe`re Seamount, between Madeira and the Portuguese mainland, covering water depths from 60 to
4,400 m. A total of 239 fishes were collected using different types of sampling gear. Three chondrichthyan species
and 31 teleosts in 21 families were identified. The collections showed a vertical zonation with little overlap,
but indications for an affinity of species to certain water masses were only vague. Although most of the species
present new records for Ampe`re Seamount, all of them have been known for the NE Atlantic; endemic species
were not found. The comparison with fish communities at other NE Atlantic seamounts indicates that despite a high
ichthyofaunal similarity, which supports the ‘‘stepping stone’’ hypothesis of species dispersal, some differences
can be attributed to the local features of the seamounts.
