Öz In this study, body composition was compared betweenfarmed female, farmed male, wild female and wild male rainbow trout; the latterescaped from farms to nature and fed natural food. The total crude protein,lipid, ash and moisture of fish meat were determined in analyses. It was foundthat there were big differences between body composition of cultured rainbowtrout and wild rainbow trout and their male and female. While in culturedfemale trouts; crude protein, crude ash moisture and lipid ratios were foundrespectively as 19.41%, 1.78%, 73.62% and 3.73%; in cultured male trouts crudeprotein, crude ash moisture and lipid ratios were found respectively as 18.73%,1.52%, 75.23% and 3.36% in wild female trouts; crude protein, crude ashmoisture and lipid ratios were found respectively as 19.65%, 1.61%, 73.83% and2.97% in wild male trouts; 19.11%, 1.39%, 75.09% and 2.53%. In the result of this research; it was found thatcrude protein and lipid content of female rainbow trout were higher; but,moisture content was lower. In addition, it was determined that the bodycomposition of rainbow trout varies according to sex, feed and habitat.
