After the analysis of the data, we established
the same dominant diatoms in comparable
proportions during the study period in the
Kaunas Lagoon and the Nemunas River:
Navicula lanceolata (Bacillariophyta), Craticula
cuspidata (Bacillariophyta) and Amphora ovale
(Bacillariophyta) (Figs. 2 and 3). The diversity
of periphyton organisms in the Kaunas Lagoon
(H = 1.79) was slightly higher than in the
Nemunas River (H = 1.77)
