Abstract: Present study consists the outcomes of fish meal protein (FMP), shrimp head protein hydrolysate (SHPH) and 11ketotestosterone (11KT) on biology of tilapia juvenile (Oreochromis mossambicus). 10 fish/ 50L were stocked in 4 treatments with 3 replicates with (mean weight, 10.03 ± 0.01 g) for 56 days. The 11KT was added to the feed (5mg/kg) by spray (+FMP, +SHPH) and was not added in control diets (- FMP, - SHPH). Specific growth rate and food conversion efficiency of fish fed on +11KT were significantly better than those fed on (-FMP or -SHPH) diets. Haemato-immunological parameters were improved in fish fed on +KT diets. Plasma T3 (triiodothyronine) levels were significantly progressed in males fish than females, whereas T4 (thyroxine) levels were increased in both sexes. Plasma 11KT levels were significantly (P < 0.05) higher in males than females. Plasma estrogen (E2) levels were insignificant in female fish. The physical parameters of water maintained at satisfactory level. These findings obviously indicate that supplemented 11KT to feeds motivated growth, simply moving the plasma levels of 11KT without producing any estrogenic activates.
