Vlasina Lake
The Ohrid trout has been successfully translocated to and bred in the Vlasina Lake in Serbia, during the 1950s and 1960s; current population status is unknown. The first lots of Ohrid trout (Salmo trutta (m) lacustris L.) were introduced in the newly formed Vlasina reservoir in 1953, when around 500,000 fish were transferred. The Ohrid trout was the dominant species in the lake at the time, but then lost its position during the 1980s, because the breeding program was discontinued, and because of failure of natural spawning due to water level variations related to working schedules of the hydroelectric plant, Vrla. Some fish still spawn successfully in the flooded tributaries of the lake. During the 1990s bleak (Alburnus alburnus) and roach (Rutilus rutilus) from Lake Ohrid were introduced into Vlasina as food for the Ohrid trout. Also a yearly program of artificial spawning and conservation efforts started.

Famous quotes containing the word lake:
“His education lay like a film of white oil on the black lake of his barbarian consciousness. For this reason, the things he said were hardly interesting at all. Only what he was.”
