Abyssal demersal fish fauna composition in two contrasting productivity regions of the Crozet Plateau, Southern Indian Ocean

► The demersal fish of the Crozet Plateau were sampled by trawl. ► Two sites with contrasting productivity were compared (M5, +Fe and M6, HNLC). ► Macrourids dominate both abundance and biomass at both sites. ► There is no statistical difference between sites due to inadequate sampling. ► Dedicated trawling cruises are required to enable appropriate numbers of replicates.
