REPRODUCTIVE ABILITY OF PERCH FEMALES (PERCA FLUVIATILIS L.) OF SHATSKY LAKES AT THEIR INVASION OF TRIAENOPHORUS NODULOSUS

A. Maistruk, National University of Life and Environmental Sciences of Ukraine, Kyiv

Fertility of the perch (Perca fluviatilis L.) in Shatskyh lakes has been investigated. The control catches of fish were conducted at the beginning of 2009 – 2011 in obedience to the given permissions. A significant difference in the size-weight indices and individual absolute fertility of infested and not infested fish of the same age group has been determined.

Key words: perch (Perca fluviatilis L.), size-weight indices, fish fecundity, gonadosomatic index.
