Abstract: (10 Views) |
Body shape, coloration, and health status are among the most important factors influencing the market value of ornamental fish. Herbal feed additives have attracted considerable attention as natural growth promoters and immunostimulants in aquaculture. This study evaluated the effects of dietary turmeric (Curcuma longa) powder on growth performance, feed utilization, survival, and hematological parameters of Green Terror (Andinoacara rivulatus). A total of 144 fish with an initial mean weight of 1.53 ± 0.22 g were randomly distributed among four dietary treatments, including a control diet and three experimental diets supplemented with 0.1%, 0.2%, and 0.3% turmeric powder. All diets were formulated to be isocaloric and isonitrogenous and were fed for 100 days. Fish were measured at 20-day intervals, and hematological analyses were conducted at the end of the experiment. Fish fed the diet containing 0.3% turmeric (T3) exhibited the highest values for growth performance, feed conversion ratio, condition factor, and survival rate; however, these differences were not statistically significant compared with the control group (p > 0.05). Red blood cell count (RBC), packed cell volume (PCV), hemoglobin concentration (Hb), and mean corpuscular hemoglobin concentration (MCHC) increased in the turmeric-fed groups, although the differences were not significant (p > 0.05). In contrast, white blood cell count (WBC) was significantly higher in the T3 group than in the other treatments (p < 0.05). Mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) tended to decrease in fish receiving turmeric supplementation, but no significant differences were observed (p > 0.05). These findings suggest that dietary turmeric supplementation at 0.3% may enhance certain hematological responses, particularly leukocyte production, while having no significant effect on growth performance in Green Terror under the conditions of the present study.
