Seaweed-Derived Marine Alkaloids: Potential Applications in Aquaculture Disease Management
Year: 2025
Type: article
Abstract: In the present research investigates the possible applications of alkaloids extracted from seaweed for controlling diseases in aquaculture production through their documented antimicrobial and antifungal as well as antiviral and immune-stimulating properties. Different types of alkaloids from Caulerpa sp., Laurencia sp., and Plocamium sp., reports on effective antimicrobial agents to fight common aquatic pathogens such as Vibrio spp., Aeromonas spp., and Saprolegnia spp. The bioactive substances offer natural antibiotic alternatives and boost immune response functions in aquatic organisms to improve disease protection and overall well-being. Sustainable aquaculture practices gain a safer disease management solution through the use of seaweed-derived alkaloids which promotes ecological protection against chemical overdoses and antimicrobial resistance formation. The study describes how alkaloids are extracted and isolated while examining their operational mechanics and effectiveness for fish health enhancement along with an evaluation of safety risks during application. Additional research should direct its focus toward improving seaweed alkaloid utilization in aquaculture by creating better formulations together with safety rules and regulatory guidelines. The potential of seaweed-derived alkaloids remains substantial because they can advance sustainable aquaculture methods and build stronger aquatic farming operations.
