The picture shows students constructing a fish pond as part of their practical training. It is not a typical sized pond. This was done just to give the students practical skills in pond construction and for in-school practical lessons.
At the moment, hand building fish pond is the common practice in Ghana because of the high cost of mechanical construction. It is large companies and very wealthy people that use the mechanical method of construction.
The most commonly cultured species are Nile tilapia, Oreochromis niloticus and African catfish, Clarias gariepinus. It is not very common to see any other species being cultured. Recently, attempts were made to culture mangrove oysters, but this hasn’t been adopted yet.
