Fish biodiversity of the Vitória-Trindade Seamount Chain, Southwestern Atlantic: an updated database

Study Extent

Primary data was acquired during three scientific diving expeditions to the VTC seamounts and islands, in 2009 (12-26 March) and 2011 (3-26 February and 1-18 April). These expeditions covered the photic and upper mesophotic zones (17-120 m depth) of the two islands and eight seamounts: Almirante Saldanha, Vitória, Eclaireur, Jaseur, "Unnamed" (Columbia Bank in [35]), Davis, Dogaressa and Columbia seamounts.

Sampling

Sampling included visual, video and photo records, as well as collection of voucher specimens by divers (hand nets and spear-guns in April 2011) using technical open-circuit SCUBA or closed-circuit rebreathers (Megalodon®) with mixed-gases (TRIMIX and EAN). Primary data from fishery surveys (surface longline, bottom longline, midwater trawling and angling activities; see [31-4,69,105]) were incorporated in the database.

Method steps

1. Fishery sampling was performed over eight volcanic mounts (Vitória, Eclaireur, Besnard, Montague, Jaseur, Davis, Dogaressa, Columbia and Trindade) by the REVIZEE and to a much lesser extent TAMAR/ICMBio monitoring assessments.
