Key facts

Oleshno lies north of the village of Pekhy and belongs to Shatsk National Nature Park. The official water-authority profile attests six fish species — Prussian carp, roach, rudd, perch, pike and tench — but no modern quantitative fish surveys or hydrochemical series have been published for the lake.

What to know

Lake in detail

  • The official water-management profile names six fish species directly; this is a lake-specific list, not the general fish fauna of the Shatsk group carried over.
  • The Prussian carp is classed as invasive, the other five species as native.
  • The water authority gives an area of 15.6 ha, a maximum depth of 3 m and a volume of 120,000 m³.
  • Scientific morphometric tables from various years give a substantially smaller area for Oleshno; the discrepancy is kept in a note rather than hidden by averaging.
  • No quantitative data on abundance, biomass or catch structure by species was found in open sources.
