The Impact of Seaweed-Derived Feed Additives (Aschomax) on Growth, Feed Utilization, Immunity, and Biochemical Profiles of Common Carp (Cyprinus carpio)

Öz

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.
