Abstract

A. The influence of the Great Meteor Seamount on the distribution of fish larvae and net plankton biomass is shown. The amount of biomass was significantly less in hauls from above the seamount than at stations beside it. The same was valid for fish larvae belonging to mesopelagic species. in addition the average length of such larvae was smaller in specimen caught above the seamount compared to those caught above the surrounding deep sea. The distribution of neritic, epipelagic, and euneustic forms seemed not to be disturbed by the seamount. Larvae of a neritic species were even more abundant above the plateau. The influence of the seamount on the oceanic biotope is discussed under faunistical aspects and under aspects of productivity.
B. Horizontal plankton hauls from a depth of 25 m distinctly showed another composition of fish larvae species than oblique tows down to a depth of 100 and 200 m. All hauls were from the oceanic area beside the seamount. Probably due to internal waves the fish larvae fauna in three of the horizontal hauls showed a surprising deviation from the other nine hauls.
