Meiofauna development on artificial soft bottoms in Kiel Bay

Abstract

The “Benthosgarten”, an enclosed area in the western Baltic Sea, is used for benthos ecology experiments. It consists of different kinds of sediment containers filled with “artificial” soft bottom. These containers were sampled by divers over a one-year period to observe the development of the meiofauna population. The first settlement, mainly by nematodes, took place immediately after exposure, and six months later the population was stabilized. The meiofauna consists mainly of nematodes and harpacticoides. Biomass and density are generally lower than in the surrounding area. Only the harpacticoid fauna is well represented by different species and has more individuals per m2 than the surrounding area. Biological aspects of the specific features of the sediment containers, e. g. size and their distance to the sea bottom are discussed.
