			At present, this ecological connectivity does not exist in many federal waterways because of regulatory measures like damming and regulation of rivers to obtain sufficiently deep [[navigation]] channels.

Therefore it is necessary to provide functional fishways for upstream and downstream migration all over Germany or achieve river connectivity by alternative measures. The BAW, in close cooperation with the Federal Institute of [[Hydrology]] (Bundesanstalt für Gewässerkunde, BfG), assists the Federal Waterways and Shipping Administration (WSV) to ensure the adherence to and implementation of biological and structural requirements using state of the art technology.

To enable and/or improve fish passage in federal waterways new structures (e.g. fishpasses) have to be realized or existing structures have to be improved. According to current scientific knowledge, in general structures for upstream migration differ from structures for downstream migration, as there are significant differences in the behavior of fish, depending on the direction of their migration.

At present the guideline´s emphasis is on issues and working steps regarding the upstream migration of fish. Some aspects of downstream migration are considered. In the guideline, apart from the working procedure, the ecological and technological-hydraulic aspects and essential factors for planning and construction of upstream [[fish pass]] facilities are presented and discussed. The guideline is to be revised to ensure the inclusion of new developments and research results.
