The maximum salinity tolerance of two freshwater Isopods, Asellus aquaticus (L.) and A. coxalis Dollf., to sodium chloride, phosphate and nitrate, has been tested in the laboratory. By means of short and medium term tests, it has been observed that these salts (above all phosphate) have a strong effect on the mortality of the two species. This demonstrates a low probability of survival of Asellus in environments which undergo natural, as well as cultural, eutrophication processes.
