Fine-scale vertical structure of sound-scattering layers over an east border upwelling system and its relationship to pelagic habitat characteristics
Ndague, Diogoul; Brehmer, Patrice; Perrot, Yannick; Tiedemann, Maik; Thiam, Abou; El Ayoubi, Salaheddine; Mouget, Anne; Migayrou, Chloé; Sadio, Oumar; Sarre, Abdoulaye (Peer reviewed; Journal article, 2020)Understanding the relationship between sound-scattering layers (SSLs) and pelagic habitat characteristics is a substantial step to apprehend ecosystem dynamics. SSLs are detected on echo sounders representing aggregated ... -
Monitoring fish communities at drifting FADs: an autonomous system for data collection in an ecosystems approach
Brehmer, Patrice; Sancho, Gorka; Josse, Erwan; Taquet, Marc; Georgakarakos, Stratis; Itano, David; Moreno, Gala; Palud, Pierre; Trygonis, Vasilis; Aumeeruddy, Riaz; Girard, Charlotte; Peignon, Christophe; Dalen, John; Dagorn, Laurent (ICES CM documents;2009, Theme session I, Working paper, 2009)An increasing proportion of landings by tuna purse seine fishing vessels are taken around drifting Fish Aggregating Devices (FADs). Although these FADs and their use by the fishing industry to capture tropical tuna have ... -
Spawning energetics and otolith microchemistry provide insights into the stock structure of bonga shad Ethmalosa fimbriata
Döring, Julian; Wagner, Carola; Tiedemann, Maik; Brehmer, Patrice; Ekau, Werner (Journal article; Peer reviewed, 2019)The gross energy content of spawning batches and the microchemistry of sagittal otoliths in individual female bonga shad Ethmalosa fimbriata were compared between contrasting sampling sites at the Senegalese southern coast ... -
Towards an Autonomous Pelagic Observatory: Experiences from Monitoring Fish Communities around Drifting FADs
Brehmer, Patrice; Sancho, Gorka; Trygonis, Vasilis; Itano, David; Dalen, John; Fuchs, Ariel; Faraj, Abdelmalek; Taquet, Marc (Journal article; Peer reviewed, 2019)This work presents a methodological synthesis for the in situ monitoring of fish aggregating devices (FADs) using a combination of optical, echosounder and SCUBA observations conducted in the vicinity of drifting FADs.
