The introduction of fish to the Scandinavian mountains by hunter-fisher-gatherers 5000 BC
Deglaciation of the Fennoscandian Ice Sheet ( c . 8000 BC) opened the mountainous areas of inland southern Norway for human habitation, but topographic barriers prevented the migration of fish into upland watercourses. Dates from four fish traps found in the exposed bed of Lake Tesse, within the central mountainous region of Norway, are reported here, with the earliest (at around 5000 BC) indicating that Mesolithic hunter-fisher-gatherers were ex…
Fish Status Survey of Nordic Lakes
The status of fish populations in 3821 lakes in Norway, Sweden and Finland was assessed in 1995-1997. The survey lakes were chosen by stratified random sampling from all (126 482) Fennoscandian lakes > or = 0.04 km2. The water chemistry of the lakes was analyzed and information on fish status was obtained by a postal inquiry. Fish population losses were most frequent in the most highly acidified region of southern Norway and least common in easte…
