This study investigates the effect of thyme extract (Thymus vulgaris) on growth and blood parameters of common carp (Cyprinus carpio). Considering the importance of nutrition in improving the performance and health of aquatic organisms, a total of 120 common carp with a nearly uniform initial weight (50 grams) were randomly divided into four groups: one control group and three experimental groups fed with 0.5%, 1%, and 2% thyme extract, respectively. The results indicated that the group fed with 1% thyme extract achieved the highest final weight (175 grams) and final length (22 centimeters). Additionally, this group exhibited the highest specific growth rate (SGR) of 2.5% and weight gain (WG) of 25 grams. In terms of blood parameters, the 1% thyme extract group showed the highest levels of hemoglobin (9.5 mg/dL), white blood cell count (6 ×103/mm³), and serum protein (4 g/dL), significantly surpassing the other groups. Furthermore, the reduction in lactate dehydrogenase (LDH) levels to 130 mg/dL in this group indicated a decrease in metabolic stress and an overall improvement in the health of the fish. These findings suggest that thyme extract can serve as an effective supplement in the diet of common carp, leading to significant improvements in growth and physiological health. Therefore, the use of natural extracts such as thyme can be recognized as a sustainable and effective strategy in the aquaculture industry, contributing to a reduction in reliance on chemical supplements.

Keywords: Thyme extract, common carp, growth, blood parameters, natural supplements, aquatic health.
