Abstract: | Experiments to determine the upper limits of potential salinity tolerance of four species of Aral Sea benthic macroinvertebrates were carried out. Invertebrates of marine origin tolerate salinity increases up to 70–90 g L–1, and the gastropodCaspiohydrobia, up to 100–110 g L–1. It was concluded that the express-method based on the estimation of salinity resistance of isolated tissues cannot be used to estimate the limits of tolerance. The prediction is made that bivalve molluscs and polychaetes will remain in the Aral Sea until the salinity increases to 60–70 g L–1, but perhaps gastropods will tolerate salinity increases to 100–110 g L–1. |
