Changes in marsh nekton communities along the salinity gradient of the river Schelde: preliminary results (poster)
In the salt marshes different habitats as well as the environmental parameters influence the composition of the nekton community. Considering both the environmental parameters and the different habitats, our sampling campaign occurred in five marshes along the River Schelde (Grembergen, Saeftinghe,...

In the salt marshes different habitats as well as the environmental parameters influence the composition of the nekton community. Considering both the environmental parameters and the different habitats, our sampling campaign occurred in five marshes along the River Schelde (Grembergen, Saeftinghe, Waarde, Zuidgors and Zwin). The salinity gradient differed from 0.2 till 29 psu. Sampling campaign occurred from April until October in 2000.Three different sampling techniques were used adapting to the different habitats.
