چکیده
This study assessed the concentrations of cadmium in the gills, livers and muscles of a commercially important tilapia fish (Sarotherodon melanotheron) from Aby Lagoon in Adiaké, Côte d'Ivoire, between January and December, 2010. The organisms were grouped into two composite samples (juvenile and adult) of five individuals. Levels of cadmium were determined in tissues using Perkin-Elmer (AAnalyst 200) Atomic Absorption Spectrophotometry (AAS) after a digestion method. Fish muscle appeared to have a significantly higher tendency to accumulate cadmium (1.19-5.18 µg/g dw) while gills and livers had minimum concentrations (0.07-1.32 and 0.12-1.25 µg/g dw). This study has revealed that the concentrations of Cd in Sarotherodon melanotheron muscle tissue were above the maximum acceptable concentrations for human consumption, thus precautions need to be taken in order to prevent future contamination.

In 1971, I spent five months in Ghana, West Africa, collecting data for an MSc thesis, "On the Ecology and Fishery of a Small West African Lagoon". I was puzzled at the time by the behavior of the fishermen who exploited the Sakumo lagoon, near Tema (Fig. 1). Based in a nearby village, they were part-timers or full-timers, but fished in either case rarely more than about 4 hours at a time, then...
