Method for the investigation of large rivers

With the MSP module macroinvertebrates, only wadeable areas of streams can be sampled and assessed. Thus, large rivers cannot be comprehensively sampled and characterized. This report presents a method for surveying macroinvertebtates in large rivers based on long-term biological studies on the High Rhine. Thereby, a methodology for sampling at the river bottom by means of diving as well as for sampling close to the riverbanks is presented.

Note: This publication is not an enforcement aid of the Confederation but an expert report.
