The two photos were taken at the Bamessing Fish Station, Cameroon. The main fish species cultured in the station are Nile tilapia (Oreochromis niloticus), African catfish (Clarias gariepinus) and common carp (Cyprinus carpio). One of the photos shows the chicken house which targets to get chicken manure for fish ponds while the second photo shows a piggery on the dyke of fish ponds from which the manure is directly released into the fish ponds.
