In the aquatic environment, seaweeds have the potential to be renewable resources. The current study was designed to assess the impact of seaweed Padina boergesenii incorporated into a basal diet at various concentrations. The phytoconstituents of the seaweeds were characterised by gas chromatography-mass spectrometry. Diets were designed to include elevated levels of 0.5%, 2.5%, 4.5%, and 6.5% of seaweed meal. Significant differences in Cirrhinus mrigala fed with P. boergesenii incorporated into the basal diet for 45 days. The growth parameters (weight gain, specific growth rate), biochemical constituents, and immunological assays were observed. The extract fraction demonstrated effective inhibitory activity against Pseudomonas aeruginosa . As a result, this research suggests that extracts of the seaweed P. boergesenii contain potential bioactive compounds with significant antibiotic activity.
