- The fish fauna of Ampère Seamount (NE Atlantic) and the adjacent abyssal plainPublication . Christiansen, Bernd; Vieira, RP; Christiansen, Sabine; Denda, Anneke; Oliveira, Frederico; Gonçalves, J. M. 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.
- The deep-sea fish Kali macrodon: a new record for the tropical eastern Atlantic off Cape VerdePublication . Vieira, RP; Thiel, Ralf; Christiansen, Bernd; Coelho, Rui; Denda, Anneke; Gonçalves, J. M. S.A new deep-sea fish is reported for the tropical eastern Atlantic. The rare chiasmodontid Kali macrodon was caught for the first time in Cape Verdean waters during an oceanographic survey in September 2009. This record provides the fifth occurrence for the species in the north-eastern Atlantic and represents the third specimen ever caught in tropical waters.
