Prilog poznavanju fitoplanktona i kvalitete vode rijeke Drave

In the summer and autumn of 1989 the qualitative composition of phytoplankton as well as some ecological factors were investigated at two different ecological localities of the Drava river: &laquo ; ; ; Zimska luka&raquo ; ; ; (20.0 r.km) withouth any streaming of water and &laquo ; ; ; Pampas&raquo ; ; ; (22.2 r.km) where the river has a naturally fast flow. The water of the investigated localities differed in measurable physical and chemical parameters. In all, 109 phytoplankton taxa were identified: 94 taxa from the locality &laquo ; ; ; Zimska luka&raquo ; ; ; and 90 taxa from the locality &laquo ; ; ; Pampas&raquo ; ; ; . According to the results of saprobiological analysis of phytoplanktonthe water of the river Drava belonged to II and II-III class of bonity. In conclusion we can say that the ecosystem of the river Drava needs a better and more adequate protection.
