The Biology of the Deep-Sea Species of Mysidacea (Crustacea) of the Rockall Trough

Abstract
The mysid fauna of the Rockall Trough consists of more than 35 species partitioned between the pelagic water column and the bentho-pelagic environment. The pelagic mysids are dominated byEucopia grimaldii, E. unguiculataandBoreomysis microps.The benthopelagic mysids, in a transect from 400 to 2900 m depth, are divided into four faunal associations.Pseudomma affinedominates the 400–800 m depth range; the impinging bathypelagicGnathophausia zoeaand the benthopelagicBoreomysis widensdominate the 800–1300 m range;Michthyops parvaandParamblyops rostrataare co-dominants in the 1400–2300 m range; whileAmblyopsoides ohliniidominates the 2170–2965 m range. The benthopelagic mysid fauna is most diverse at depths below 1400 m. It is dominated by species whose geographical distribution is restricted to the North Atlantic, in contrast to the pelagic mysid fauna, which is dominated by cosmopolitan species. Notes on the breeding season, biology and population structure of several species are given.
