The vertical distribution of micronektonic Decapoda and Mysidacea (Crustacea) is examined along a cross-slope transect of stations with soundings ranging from 192 m to 1800 m in the Porcupine Seabight during spring 1994. Eight species were found only at the three deep-water open oceanic stations to the west of the slope, while the horizontal ranges of others extended from deep-water to the outer (lower) slope station. The numbers of species caught at the inner (upper) slope and shelf station were lower than offshore. The species assemblages were broadly different at the deep-water, upper slope and shelf stations with no species occurring continuously across the whole of the transect. Three deep-living species were found in higher concentrations near-bottom over the slope than at similar depths at the adjacent open ocean stations. Factors affecting distribution of species are discussed.
