Abstract :The overuse of antibiotics and synthetic feed additives in aquaculture involves risks to fish health and the environment. Finding natural alternatives to synthetic materials is critical for sustainable aquaculture enter-prises. The present study was conducted to investigate the effects of Seaweed-Derived Feed Additives (Aschomax) supplementation with different concentrations (0%, 1%, 2%, and 3%) on growth, feed utiliza-tion, immunological parameters, and blood biochemical indices of common carp (Cyprinus carpio) over a 60-day feeding period. The results demonstrated that growth performance parameters were significantly en-hanced in fish fed with 2% Aschomax supplementation. Moreover, immunological parameters were markedly improved across all Aschomax-supplemented groups, with the 2% inclusion level showing superior results. This was evidenced by significantly elevated levels of Myeloperoxidase (MOP: 0.59%), Nitroblue tetrazolium (NBT) activity (38.5%), and lysozyme activity (37.8 U/mL), indicating enhanced non-specific immune re-sponses. Furthermore, 2% of Aschomax demonstrated the most favorable lipid profile, characterized by re-duced total cholesterol (TC) (140.21 mg/100 ml) and triglycerides (TG) (75.23 mg/100 ml), alongside elevat-ed high-density lipoprotein (HDL) (93.60 mg/100 ml) and reduced low density lipoprotein (LDL) (50.54 mg/100 ml) levels. Notably, liver enzyme activities (ALP, ALT, and AST) remained unchanged across all treatments. These findings suggest that Aschomax supplementation at 2% effectively enhanced growth per-formance and stimulates the immune system of C. carpio. The alteration in blood biochemical parameters suggests improved metabolic efficiency and overall health status.
