Fish pathology is a specialized field within aquatic animal health that focuses on the study, diagnosis, and management of diseases affecting fish. It encompasses a wide range of disciplines, including microbiology, parasitology, immunology, and environmental science, to understand the causes and impacts of infectious and non-infectious diseases in both wild and cultured fish populations. With the rapid expansion of aquaculture, the incidence of fish diseases has become a major concern, affecting productivity, sustainability, and economic viability. Pathogens such as bacteria, viruses, fungi, and parasites are responsible for significant losses in aquaculture systems.

Moreover, environmental stressors like water pollution, poor nutrition, and overcrowding further exacerbate disease outbreaks. Fish pathology plays a critical role in early disease detection, biosecurity, vaccine development, and health management strategies. Advancements in molecular diagnostics and immunological techniques have improved the accuracy of disease identification and monitoring. Research in this field is essential for developing effective treatments and preventive measures, ultimately supporting the sustainable growth of aquaculture industries worldwide. The Journal of Aquaculture & Fisheries continues to publish cutting-edge studies and reviews in fish pathology to support researchers, veterinarians, and aquaculture practitioners in addressing these pressing health challenges.
