USE OF FAUNAL INDICATORS FOR ASSESSING THE IMPACT OF A PORT ENLARGEMENT NEAR BILBAO (SPAIN)

摘要

In order to assess the effects of the execution of the `Port of Bilbao Enlargement Project', epifauna living on hard substrata and enviornmental parameters were quantitatively investigated from 1994 to 1996. A programme of repeated non-destructive sampling at 8 stations was carried out during the construction perido of a breakwater and the filling oeprations on the shoreline. A correlation analysis was used as a method to extract potential indicator species of particular environmental conditions measrued in the field.
