	abstract = {The Prespa nase, Chondrostoma prespensis, lives exclusively in Lakes Mikri and Megali Prespa in north-western Greece. The Prespa nase fishery catches in both lakes began declining in the early 1980s, probably due to overfishing. However, the population of Lake Mikri Prespa, which has been monitored from 1984 to 1996, has shown an increase since the early 1990s thanks to the use of larger mesh size and a decrease in the fishing effort of the fishery. The population of Lake Mikri Prespa seems unique for the genus because it lives in a lentic ecosystem which is lacking any permanent inflow streams, the Prespa nase being therefore forced to spawn within the lake. In contrast, the population of Lake Megali Prespa do undertake spawning migration into permanent inflows. This migration was studied in 1995 and 1996 in the Agios Germanos stream, starting late April to late May. Only large mature fish visit and spawn in this stream, the migration taking place exclusively at night. Migrating at night may protect them from diurnal predation from waterbirds.},
