Résumé

Geographical distribution of biomass and species, community structure, and size comparisons of pelagic shrimps were investigated in the upper 1000m in the Southern Ocean between 150° E and 115° E during the austral summer (December 1985 and January 1986). The biomass ranged from 0 to 4.25 g wet weight/1000 m3 collected by the IKMT and in general tended to decrease southward. The average biomass north of the Polar Front and in the Antarctic Zone was 2.55 and 0.40 g/1000 m3, respectively. Twenty species were collected and of these eight were in the Antarctic Zone. Pelagic shrimps in the study area were assigned to four categories by their geographical distribution. The first included five upper meso-pelagic species and was restricted to the Subtropical Zone. The second included seven lower meso-pelagic species and occurred in the Subtropical and Subantarctic Zones. The third included seven lower meso-and bathy-pelagic species and was distributed from the Subtropical Zone to the Antartic Zone. The fourth category of one species was distributed from the Subantarctic Zone to the Antarctic Zone. We suggest that oceanic fronts in the study area do not constitute a distributional barrier to lower meso-and bathy-pelagic shrimps.
