Metin YAZICI is an aquaculture researcher at Iskenderun Technical University (Faculty of Fisheries and Marine Sciences, Dept. of Aquaculture and Fish Diseases). His work focuses on fish nutrition and functional feeds (probiotics, prebiotics, synbiotics; phytochemicals), immune modulation and mucosal immunity, oxidative-stress responses, histology/histomorphometry, and the regulation of growth/appetite and inflammation-related genes. Centering on sustainable aquaculture and antibiotic-use reduction within a One Health perspective, he investigates alternative protein sources (insect/mealworm meals, Schizochytrium sp. microalgae, macroalgae). Recent studies in Oncorhynchus mykiss, Danio rerio, and Cyprinus carpio report improvements in growth, immunity, and liver/intestinal health. His publications appear in Fishes, Aquaculture Nutrition, Fish & Shellfish Immunology, and Aquaculture Reports.
