 abstract={A comparison of the primary production (14c), its PHAR efficiency, daily P : B ratio, and the composition, biomass and dynamics of the phytoplankton, zooplankton and bacterioplankton, of the littoral and profundal benthos, as well as of the emergent and submerged vegetation of five lakes connected by the Jorka river indicates a consistent pattern of mesotrophic status in L. Majcz Wielki (deep, dimictic), of eutrophic status in L. Inulec and L. Jorzec (shallow, with a high internal and external loading), and of „mixotrophic” status in Głębokie L. (deep, dimictic) – originally mesotrophic, but at present enriched and polluted by an aquaculture (Salmo gairdneri Richardson).},
