Abstract: | Characteristic of population biology of the "sepetang" clam has been studied in Dumai mangrove ecosystem from November 2010 to October 2011. lbis research was to study the patterns of the population growth, mortality and recruitment of the clam P. acutidens. Sampling was monthlyfrom plot 1 m x 1 m quadratic transects. The result showed that growth pattern of P. acutidens was negative allometric with asymptotic length (Leo) 92.71 mm.The annual growth coefficient (K) and total mortalitywere 0.59 and 1.87 per year, respectively. The natural mortality was probably related to environmental condition. The recruitment occurred every month, the peaks occurred on April (15.93%) and August (13.16%).
