Four treatments designated as T1, T2, T3 and TC with three replicates were installed in the Wet laboratory of College of Fisheries. Varied diets were supplemented with U. dioica at different rate i.e., 0.5 g, 0.75 g and 1 g/kg feed for treatment T1, T2 and T3 respectively while treatment TC was given control diet. The physico-chemical parameters of water like temperature, pH, dissolved oxygen, free carbon dioxide and total alkalinity were found to be within optimum range. There was no adverse effect observed on water quality parameters due to incorporation of U. dioica on fish diets. The phytochemical analyses of U. dioica leaves revealed the presence of flavonoids (37.21 μg/ml), alkaloids (25.39 μg/ml), tannin (6.15 μg/ml), terpenoid (2.516 μg/ml), glycosides (1.096 μg/ml), phenolic (297.5 μg/ml) and saponin was absent. The different diets supplemented with U.dioica showed increased on growth performance of experimental fishes. The best results for growth parameters like net weight gain (415c±.547 g), net length gain (4.2d±.034 cm), percent weight gain (85.65c±.400 %), specific growth rate (.298c±.008 %), gross conversion efficiency (.229c±.006), feed conversion ratio (4.37a±.132) and condition factor (1.53b±.011) were recorded in treatment T3 in comparison with the treatment TC (control). No mortality was observed in all the treatments which resulted in the 100% survival rate. The haematological parameters (like haemoglobin level, total erythrocyte count, and total leukocyte count etc) and serum biochemical parameters (including total serum protein, albumin and globulin) showed increased results for the treatment T3. From the above study it is suggested that the herb U. dioica leaves powder be supplemented at the rate 1g/kg in fish feed for increasing growth, haematological and serum biochemical parameters of Amur carp (Cyprinus carpio haematopterus).EnglishThesis
