In June 1983 a whole-catchment liming experiment was conducted at Tjønnstrond,
southernmost Norway, to test the utility of terrestrial liming as a technique to restore fish …

Two sediment cores from acid lake Store Hovvatn were analysed for chironomid head
capsule remains over a sequence spanning from about 1730 AD to the late 1970s. Up to 30 …

Repeated liming of Hovvatn during the 1981–1995 period assured successful reintroduction
of lake spawning brown trout, Salmo trutta. Poor natural recruitment to the population was …

The primary goal of liming is to improve water chemistry, specifically to decrease acidity and
increase buffering capacity. The desired end results are increased fish abundance and …
