Abstract
Freshwater fi sh communities have always been valuable resources
for society, particularly the species that migrate between
freshwater and the sea. Historically, eel, salmon and trout were
so abundant that good fi shing luck could turn a capable fi sherman
into a wealthy person. Unfortunately, migrating fi sh became
threatened by over-fi shing quite early in human history. The
more recent construction of dams and other habitat destruction
associated with development of towns, industries and intensive
agriculture have reduced populations further. The largest Danish
river, the River Gudenå, illustrates this historical decline and
also the diffi culty of re-establishing healthy fi sh communities
once the original populations have deteriorated or, in the case of
salmon, become extinct. Efforts are currently needed to be made
to effectively restore and manage fi sh communities in streams.
