An in-situ study was conducted in the Sine Saloum Delta with the objective of studying the growth rate of Anadara senilis according to size and tide variation. The study revealed a minor allometry with values of 2.60 and 2.53 in the consistently submerged area and intermittently submerged area, respectively. The Von Bertalanffy linear growth parameters estimated from the ELEFAN in R Software are L∞ = 58.1 mm; K = 0.20, t0 = -0.70 and Φ’ = 2.83 in the intermittently submerged area and L∞ = 53.2 mm; K = 0.31; t0 = - 0.46 and Φ’= 2.94 in the consistently submerged area. The growth rate is inversely proportional to the size of the individual. The results of this study should help to develop strategies for the sustainable management of A. senilis in Sine Saloum Delta.
