Abstract :

Pharmaceutical compounds are useful role in the growth of ornamental fish. To investigate the effects of Clomiphene on food ratio and growth factors in Gourami fish species (Trichogaster trichopterus) was done.  The Growth rate increasing was aimed for Achieving to more fish count in shorter time and less costs in the hatchery and fish farming. The numbers of 140 gourami fishes were fed for 2 month with dietary supplementation impregnated with different ratio of clomiphene (1, 1.5 and 2 mg/kg in dry diet), in 4 groups includes (a control group and 3 treatment groups). Fish biometric assay (total weight and standard length) were performed every two weeks and growth indices were calculated monthly. The results have shown that the use of clomiphene in the diet of growth factors (body weight increase, percentage of body weight increase, specific growth rate, protein efficiency ratio, average daily growth) was significant and positive effected, but food conversion factor was decreased significantly. Therefore, Clomiphene can be used as an additive and dietary supplementation in feed for Gourami fish Trichogaster trichopterus (3 spots gourami).
