The fish and fisheries of three fish landing sites around the Keta lagoon in Ghana have been studied. A total of 18 fish species belonging to 13 families were encountered in the study. Four of the species were found to be commercially important notably, the cichlids (Tilapia guineensis and Sarotherodon melanotheron), the Bonga shad, (Ethmalosa fimbriata) and the blue-swimming crab, (Callinectes amnicola).
A random assessment and human risk analysis were conducted on 80 groundnut pastes and raw groundnuts from some local markets across the different agroecological zones of Ghana.
