Dr. Majid Khanzadeh is a fisheries researcher specializing in aquaculture, fish immunology, and nutritional biotechnology. His work focuses on enhancing fish health, immunity, and growth through the use of natural bioactive compounds, such as algae extracts, fucoidan, and plant-based supplements, as well as through the development of vaccines and probiotics. He has published extensively in international journals including Frontiers in Marine Science, Aquaculture Nutrition, and Fish & Shellfish Immunology, contributing over fifteen peer-reviewed papers between 2020 and 2025. His studies explore immune modulation, antioxidant defense, and sustainable disease prevention in cultured species like tilapia, trout, and Asian seabass. In addition to publishing and presenting at global conferences, he has contributed to books on immunology and mucosal health in aquaculture, participated in national research projects, and served as a peer reviewer for leading scientific journals, underscoring his active role in advancing modern aquatic animal health and sustainable aquaculture systems.
