Main Module

New methods for sampling ostracods are described specifically for hyporheic environments and coarse sediments (i.e., pebbles and rocks). The main module is a diaphragm pump that establishes an artificial current strong enough to force individuals from their habitat. Two other methods are presented for separating living ostracods from sediment samples taking advantage of their biological and physical properties: (1) emigration out of a basket; (2) harvesting ostracods floating on the water surface.
