The paper presents the results of the study of abundance and secondary production of neustonic and planktonic bacteria inhabiting estuarine Lake Gardno. The obtained data indicate that numbers of bacterioneuston were only slightly higher than of bacterioplankton. The rate of secondary production of bacteria was higher in the film layer than in the surface layer and subsurface water. Bacterial abundance and production were changing with seasons. Differences among studied bacteriological parameters were determined among sites across Lake Gardno.

W pracy przedstawiono wyniki badań dotyczących oznaczenia ogólnej liczby i produkcji wtórnej bakterioneustonu i bakterioplanktonu zasiedlającego estuariowe przymorskie jezioro Gardno zlokalizowane na terenie Słowińskiego Parku Narodowego. Badania mikrobiologiczne prowadzono w trzech warstwach wody (film, błona powierzchniowa, woda podpowierzchniowa). Uzyskane wyniki badań wykazały, że ogólna liczba bakterii neustonowych była nieznacznie większa niż bakterii planktonowych. Poziom produkcji bakteryjnej w filmie powierzchniowym był wyższy niż w błonie powierzchniowej i podpowierzchniowej warstwie wody. Wykazano znaczące różnice wartości badanych parametrów bakteriologicznych w różnych częściach badanego jeziora. Stwierdzono znaczącą dynamikę zmian sezonowych liczebności bakterii i ich produktywności.
