- Cleaning interactions of fishes at São Tomé Island, West AfricaPublication . Vasco Rodrigues, Nuno; Fontes, Jorge; Bertoncini, A.This study reports six new types of cleaning interactions among tropical reef fish species at São Tomé Island, and confirms previously reported interactions for this area. Spicara melanurus was recorded as a cleaner for the first time, and Abudefduf saxatilis was confirmed in this role, following reports from the Southwest Atlantic. Individuals belonging to the family Labridae were the most commonly-observed cleaners, involved in over 85% of recorded interactions. Juveniles of Bodianus speciosus played a key role as cleaners, interacting with at least seven client species. In addition, some of the client fishes, including Paranthias furcifer and Acanthurus monroviae, interacted with at least four cleaner fish species. All cleaner fish species reported in this study were facultative; obligate cleaners appear to be absent from this region.

However, this information is lacking at a global scale. Here we show, using a big-data approach that combines satellite-tracked movements of pelagic sharks and global fishing fleets, that 24% of the mean monthly space used by sharks falls under the footprint of pelagic longline fisheries. Space-use hotspots of commercially valuable sharks and of internationally protected species had the highest overlap with longlines (up to 76% and 64%, respectively), and were also associated with significant increases in fishing effort. We conclude that pelagic sharks have limited spatial refuge from current levels of fishing effort in marine areas beyond national jurisdictions (the high seas). Our results demonstrate an urgent need for conservation and management measures at high-seas hotspots of shark space use, and highlight the potential of simultaneous satellite surveillance of megafauna and fishers as a tool for near-real-time, dynamic management.

- Ten new records of marine fishes for São Tomé, West AfricaPublication . Vasco Rodrigues, Nuno; Fontes, Jorge; Bertoncini, Áthila AndradeThree chondrichthyes: Rhincodon typus Smith, 1828; Mobula tarapacana (Philippi, 1892); and Mobula thurstoni (Lloyd, 1908), and seven teleosts: Beryx decadactylus Cuvier, 1829; Peristedion cf. cataphractum (Linnaeus, 1758); Coryphaena hippurus Linnaeus, 1758; Liopropoma emanueli Wirtz et Schliewen, 2012; Chromis cadenati Whitley, 1951; Chromis limbata (Valenciennes, 1833); and Makaira nigricans Lacepède, 1802 were recorded for the fi rst time for São Tomé. These records were based on fi shes landed in local markets, captured, or observed while SCUBA diving and from BRUV surveys.
