Turmeric extract (TE) is known for its potential health-promoting and stress-resilience properties across various species. The research evaluated the effects of dietary TE supplementation on the health and stress resilience of goldfish (Carassius auratus). Over 8 weeks, 480 fish (10.70 ± 0.5 g) were randomly assigned to six groups, with 10 replicates per group (8 fish per replicate). The control group (Group 1) was fed a basal diet without any supplementation. In contrast, the other groups received diets supplemented with TE at the following concentrations: 1 g/kg for Group 2, 2 g/kg for Group 3, 2.5 g/kg for Group 4, 3 g/kg for Group 5, and 4 g/kg for Group 6. Although growth performance and feed intake were unaffected by TE supplementation, significant improvements in fish coloration were observed, particularly in the head, abdominal, and tail regions. According to the research, adding TE to goldfish meals enhanced immunological response, decreased biomarkers linked to stress, and increased general well-being and stress tolerance. The 4 g/kg group showed the highest increase in serum carotenoid levels, while higher white and red blood cell counts, total protein, albumin, and globulin levels were observed. TE supplementation also reduced plasma cortisol and glucose levels, suggesting enhanced stress resistance. The research suggests that TE supplementation can enhance overall health and stress resilience in goldfish.
