Dear All

As many of you are aware a task team was established last year to develop a national presence map of Nile tilapia, Mozambique tilapia and its hybrids in South Africa, showing the presence or absence of the species.

One of the first priorities (Objective A of the Project) was to map distribution of Nile and Mozambique tilapia and its hybrids, using existing literature and a Citizen Science survey. The first iteration of this mapping exercise is now complete.

It is important to note that the current mapping is by no means the final indicator of where Nile tilapia, Mossambicus tilapia and its hybrids occur. What the maps represent are baseline departure points for further review and specialist field survey work to verify the distribution mapping.

We therefore encourage you to download the maps from the link below and to give further input in those instances where you are aware of the presence of Nile tilapia, Mossambicus tilapia and its hybrids, which are not reflected on the maps.

Please email Heather Terrapon ( with the information you would like to include and use the subject line: Nile tilapia mapping

There is a lot of data in the folder and we know in rural areas the broadband connectivity is not always strong enough to download large files. We have made the river list and the metadata available on our website as a quick aid to those who are struggling to download the information.

This can be found at the bottom of the page at the following link:

Please use this opportunity to give input – the mapping process is entering a critical phase where the field work will be undertaken. To ensure this process yields meaningful results we need to have as much information as possible at the disposal of the scientific teams.
