Lokoska, L. (Hidrobioloski zavod, Ohrid (The Former Yugoslav Republic of Macedonia))
During 2001, water from river Cerava and from the littoral where the river flow into lake Ohrid, were examined. Bacteriological analysis included ecological and sanitary aspekt of water state. Heterotrophic, proteolytic, amylolytic and phosphomineralizing bacteria, most probable number of total coliforms (MPN) and presence of Escherichia coli and Clostridium perfringens were determined. The results of investigations shows organic and faecal pollution and permanent negative anthropogenic effects.

Talevska, M. (Hidrobioloski zavod, Ohrid (The Former Yugoslav Republic of Macedonia))
In this paper investigations of biomass of red head grass Potamogeton perfolitus L. from Lake Ohrid were presented. The material was collected from 2 localities along the Ohrid Lake's coast (Grasnica and Kaneo), where anthropogenic influence is different expressed. The results from the investigations show that there are differences in biomass between investigated localities.
