Hence, high attention has been devoted to improvement of FA content in flesh of farmed animals through nutrition. FA composition of animals is aside nutrition, as a main part of environmental factors, determined also by genetic factors where knowledge is poor.  In fish, an important source of PUFAs for humans, information about genetic variation of FA content is totally missing. The aim of this study was to determine the genetic variation of FA content in common carp, a very important fish in freshwater aquaculture. Material and methods Fish for this study were taken from a stock established for purposes of an experimental breeding program. The stock arose by full-factorial cross (crossing each female with each male) of 8 females and 96 males using an artificial reproduction. All parents were genotyped for X microsatelittes from fin tissue. Fish grew up under semi-intensive pond conditions till market size (1395 ± 273,4 g). Fish fed on natural and supplemental food (see Figure 1). At the market size, all su
