Description
The study aimed to explore the potential of seaweeds Sargassum wightii and Gracilaria corticate fermented using Bacillus subtilis MN960600 (CK4). Fermented seaweeds showed enhanced antioxidant activity in DPPH assays. A second-order model known as Box-Behnken was used to create an optimized quadratic design for fermentation parameters enhancing protein, reducing sugars, and lipid yields. This optimized feed demonstrated significant growth improvement of 18 to 20 % in Oreochromis niloticus when compared to commercial feed and a 35 to 40% higher growth in fermented and non-fermented feed groups. Additionally, fish fed formulated seaweeds exhibited resilience to Vibrio harveyi and Aeromonas hydrophila pathogen stress. Additionally, the study highlighted the ability of the formulated seaweed in reduction of oxidative stress caused by pathogens Vibrio harveyi and Aeromonas hydrophila in Oreochromis niloticus. The study emphasized the potential use of seaweeds and probiotic bacteria as a sustainable aquafeed. 2025, Egyptian Society for the Development of Fisheries and Human Health. All rights reserved.
