✦ Synopsis

Longitudinal transects in the Schlei Fjord (Kiel Bight) revealed strong increases of microbiological parameters from the entrance towards the landlocked end of the fjord. In the inner part up to 14 x 106 bacteria mlsi (microscopical count), 77 x lo3 saprophytic bacteria ml-1 (plate count) and a thymidine incorporation rate of 0.436 nmol 1-1 h-1 were observed. The data were compared with earlier results from the same system and those from the nearby located Kiel Fjord. The observations indicate a very high degree of eutrophication in the Schlei Fjord and a lesser one in the Kiel Fjord. The significance of total bacterial numbers and numbers of saprophytic bacteria as indicators for eutrophication and contamination is discussed.

K. GKKE and G. RHEINHEIMER

This chapter will give some information about the influence of eutrophication on some important bacterial parameters in the two western Baltic fjords and the meaning of bacteria as indicators for eutrophication will be discussed.
