Abstract

Our research on a population of Austropotamobius pallipes italicus (Faxon, 1914) in the protected karstic limnocrenic spring Modro oko (Dalmatia, southern Croatia) was carried out between February and October 1995. Data were collected on the density of crayfish population, the depth at which specimens were caught, water salinity, water temperature, alkalinity, concentra-tions of nitrite, ammonia and phosphate and the presence of chlorophyll a. We also examined submersed vegetation as a potential microhabitat for this species. The aim of our research was to discover a possible correlation between some of these parameters and the number of crayfish. Small negative correlation was found between population density and water salinity and population density and concentration of phosphate. A positive correlation was found between the number of crayfish and the water temperature and the number of crayfish and the depth at which they were caught. The water temperature was relatively stable throughout the year.
