The purpose of this poster is to enhance the capacity of hatcheries, nurseries, grow-out farmers and extension service providers to recognize and report tilapia diseases. Prevention, early recognition, diagnosis and rapid intervention are the best steps to manage aquatic animal diseases. If you observe clinical signs, abnormal behaviour and unusual mortality, contact your local aquaculture health professionals to report and ask for support.

In terms of quantity produced, Catla catla is the sixth most important finfish aquaculture species produced globally in 2015. It is primarily grown in South Asia, often on a small scale in polyculture with other species. In spite of its economic importance, in a number of countries, including Bangladesh, the quality of catla seed produced in hatcheries has historically suffered from high levels of inbreeding, uncontrolled interspecific hybridisation and negative selection.
