Abstract

The phytal fauna of the SW Baltic was investigated at three localities of the German coast:
Flensburg fjord (Kiel Bight), Dahmeshöved (Lübeck Bight) and Salzhaff (NW Mecklenburg). The samples
comprised fi ve algae species (Fucus vesiculosus, Ceramium sp., Enteromorpha sp., Ectocarpus sp., Chorda sp.), two
spermatophytes (Zostera marina, Zannichellia palustris) and animal aufwuchs by Mytilus edulis. Additionally,
succession experiments were performed in the Mytilus and Ceramium belts of Dahmeshöved. The investigations
were focused on the organisms living between the sub strate and their possible exploitation by fi sh.
Therefore, the question arose what substrate is best suited to be colonized by “invertebrates”. At all three
localities highest biomass was found in the Ectocarpus belt in late spring, in Ceramium, Enteromorpha and Mytilus
belts in summer. The Zostera belts presented highest values in spring, whereas Fucus and Zannichellia belts
attained relatively low values. Production of fi sh prey animals was highest in Enteromorpha belts followed
by Ceramium and Mytilus belts. F. vesiculosus attained low values in Flensburg fjord but clearly higher values
in Salzhaff. The index of settlement which expresses the utilization of the substrate by fi sh prey organisms
was highest in Enteromorpha belts, followed by Ceramium, Fucus and Zostera belts from Salzhaff. At the end of
succession areas biomass of Mytilus and Ceramium belts was lower than in the control areas but taxa numbers
were higher. In these experiments the Mytilus belt attained slightly higher biomass values than the Ceramium
belt. The Enteromorpha and Ceramium belts proved to be especially suited reservoirs for fi sh prey organisms.
