Abstract
Tilapia is an affordable protein source farmed in over 140 countries with the majority of production in low- and middle-income countries. Intensification of tilapia farming has exacerbated losses caused by emerging and re-emerging infectious diseases. Disease diagnostics play a crucial role in biosecurity and health management to mitigate disease loss and improve animal welfare in aquaculture. Three continuous levels of diagnostics (I II and III) for aquatic species have been proposed by Food and Agriculture Organization of the United Nations (FAO) and the Network of Aquaculture Centers in Asia and the Pacific (NACA) to promote the integration of basic and advanced methods to achieve accurate and meaningful interpretation of diagnostic results. However the recent proliferation of cutting-edge molecular methods applied in the diagnosis of diseases of aquacultured animals has shifted the focus of researchers and users away from basic approaches and toward molecular diagnostics despite the fact that many diseases can be rapidly diagnosed using inexpensive simple microscopic examination and that most emerging diseases in aquaculture were discovered by histopathology. This review therefore revisits and highlights the importance of the three levels of diagnostics for diseases of tilapia particularly the frequently overlooked basic procedures (e.g. case history records gross pathology presumptive diagnostic methods and histopathology). The review also covers current and emerging molecular diagnostic technologies for tilapia pathogens including polymerase chain reaction methods (conventional quantitative digital) isothermal amplification methods Loop-mediated Isothermal Amplification (LAMP) recombinase polymerase amplification (RPA) clustered regularly interspaced short palindromic repeats (CRISPR)-based detection lateral flow immunoassays as well as discussing what is on the horizon for tilapia disease diagnostics (next generation sequencing artificial intelligence environmental Deoxyribonucleic Acid (DNA) and Ribonucleic Acid (RNA) and point-of-care testing) providing a future vision for transferring these technologies to farmers and stakeholders for a sustainable aquatic food system transformation. ? 2023 Food and Agriculture Organization of the United Nations.
