AB Taxonomic composition, abundance and biological features of micronektonic fish were investigated using pelagic trawls conducted near and over the summits of three seamounts located in the western Indian Ocean (La Pérouse, MAD-Ridge and Walters Shoal). Mesopelagic fish from three families accounted for 80% by number of the total catch (5714 specimens, 121 taxa), namely myctophids (59%), gonostomatids (12%) and sternoptychids (9%). Whereas the gonostomatid Sigmops elongatus was the most abundant species around La Pérouse seamount, myctophids were the most diverse and dominant group by number in all three studied areas. Most myctophids were high-oceanic species, which included the numerically dominant Benthosema suborbitale, Ceratoscopelus warmingii, Diaphus perspicillatus, Hygophum hygomii, and Lobianchia dofleini. The few remaining myctophids (Diaphus suborbitalis being the most abundant) were pseudoceanic fish, highlighting the association with landmasses. The study adds one myctophid species new to the Indian Ocean (Diaphus bertelseni), and a second record in the literature of the recently described sternoptychid Argyripnus hulleyi.
