Abstract: Bio-ecological assessment of clams of lower Sanaga Delta. Cameroon showed that clams of this area are in general burrowing bivalves with predominate shell oval shape (96.3%). with nuance of yellow coloration (62%). presenting lengths between 30 and 90 mm. The granulometry of clam fishing ground was predominantly fine sand (<0.25mm) with high temperatures (23–27 °C) and excessive salinity. Polluted slightly by chemical compounds such as nitrates. ammonium. Phosphates and chlorides. Some water characteristics (pH. sulphate. nitrate and fluoride) showed some influence on metric parameters of the clam (height (H). length (L) and Bulge (B)) with respective positive correlation with the fluoride ions (0.798; 0.802 and 0.662) while the same metric parameters (L. H and B) were negatively correlated with other compounds of water with respective r- values for L. H and B for pH (-0.764. -0.766 and 0.655); nitrate (-0.695. -0.691 and 0.625) and sulphate (-0.855. -0.855 and 0.769).
