According to figures from the FAO, Egypt and Bangladesh are the third and fourth largest tilapia producers, respectively, after China and Indonesia. Absence of accurate baseline data relating to fish health, disease occurrence, diagnostic services and health economic hamper surveillance and disease control efforts. To overcome some of these shortcomings, and generate background data upon which trends and emerging issues may be assessed, WorldFish and partners developed a Tilapia epidemiology and health economics online survey tool.
