Length-weight relationships of six syngnathid species from Ria Formosa, SW Iber...
Vieira, RP; Monteiro, P.; Ribeiro, J.; Bentes, L.; Oliveira, F.; Erzini, Karim; Gonçalves, J. M. S.In this study, the length-weight (LWR) parameters were estimated for six syngnathid species, including 2 seahorses and 4 pipefishes, from Ria Formosa, a temperate lagoon from the south coast of Portugal. A total of 5070 fishes were used to determine the LWR. The estimated b value ranged from 2.95 (Nerophis ophidion) to 3.36 (Syngnathus abaster). To the authors' best knowledge, LWR parameters were estimated for ...
The fish fauna of Ampère Seamount (NE Atlantic) and the adjacent abyssal plain
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...
Weight-length relationships for five fish species from a temperate coastal lago...
Vieira, RP; Bentes, L.; Monteiro, P.; Ribeiro, J.; Erzini, Karim; Gonçalves, Jorge Manuel SantosThe weight-length relationships (WLR) were estimated for five fish species of Ria Formosa, a coastal lagoon in southern Portugal. WLRs for Gobius couchi, Pomatoschistus microps and Parablennius pilicornis were determined for the first time ever and for Gobius cruentatus for the first time for the southern European Atlantic coast.
The deep-sea fish Kali macrodon: a new record for the tropical eastern Atlantic...
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.
