К экологии речного окуня (Perca fluviatilis Linnaeus, 1758) из водоемов Сибири

On territory of Siberia the perch (Perca fluviatilis Linnaeus, 1758) habit in a number of rivers, lakes and reservoirs. The perch is very adaptive to habit condinions in oligotrophic and mesotrophic reservoirs. In the lakes with concentration of salt more 2,0-2,5 ‰ the perch do not breed. The maximal life duration of perch in Siberia reservoirs – 22 years, maximal lehth of body – 35-37 sm, biggest massa of body (Q) – 1,8-2,0 kg. However, et big number and deficit of food maximal length of perch body composes 10-12 sm, and massa – 50-100 g. In the many rivers and reservoirs of Siberia the perch is numerous and is objects of fishering. The study of perch ecology in reservoirs of Siberia probably continue, the reasons of this were show above.
