Abstract Brown trout is a common type of fish grown for consumption in open and flowing ponds on the rivers Bosnia Herzegovina. We conducted this study during three seasons (spring, summer autumn) to obtain complete picture morphological histological characteristics selected tissues. The physicochemical water from Pliva River near Pljeva pond where intensive breeding carried out were analyzed. These analyses have shown that there are no major deviations quality excellent quality. A total 90 harvested all their morphometric determined by analyzing ten parameters. After dissection individuals, stereological analysis was performed compare tissues liver, stomach, gills muscles. showed significant differences histoarchitecture compared river. Liver tissue had altered hepatocyte shape presence adipocytes; stomach stronger mucosa weaker muscle layer; gill lower respiratory lamellae; while adipose brown living those All these changes due commercial feed inability move freely.
