Fisheries / fish farming and restoration of streams to allow fish re-stocking
Danish term or phrase: ændring af tre styrt i Vesterbæk til stryg/gydebanker
'Styrt' would normally be fall, but perhaps there is a definite technical term in this context? Also 'stryg' - which could just be stream?

Explanation:

In Denmark, due to its hilly lowland geography, streams tend to be slow-meandering, sometimes even quite sluggish. Nothing like fast-flowing Alpine or US West Coast / Alaskan streams with little or larger waterfalls.

there are images on the internet of fishways with just one or two "rungs / steps" which could also apply to low-gradient streams
