Abstract

In this study, body composition was compared between
farmed female, farmed male, wild female and wild male rainbow trout; the latter
escaped 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 found
that there were big differences between body composition of cultured rainbow
trout and wild rainbow trout and their male and female. While in cultured
female trouts; crude protein, crude ash moisture and lipid ratios were found
respectively as 19.41%, 1.78%, 73.62% and 3.73%; in cultured male trouts crude
protein, 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 ash
moisture and lipid ratios were found respectively as 19.65%, 1.61%, 73.83% and
2.97% in wild male trouts; 19.11%, 1.39%, 75.09% and 2.53%.

In the result of this research; it was found that
crude protein and lipid content of female rainbow trout were higher; but,
moisture content was lower. In addition, it was determined that the body
composition of rainbow trout varies according to sex, feed and habitat.
