For the management of mollusc resources, knowledge of various population parameters and exploitation level of the population of wedge clams are needed. Population dynamics on wedge clam, Donax scortum is still unknown in Asia. FAO-ICLARM Stock Assessment Tools (commonly known as FiSAT) was used for calculating population parameters of this species. The specimens of D. scortum were collected from Padukere sandy beach at monthly intervals from February 2009 to January 2010. Asymptotic length (L α) was 70.88 mm and growth coefficient (K) was estimated at 0.64 year−1. The sizes attained by D. scortum were 33.51, 51.17, 60.49, 65.40, 67.99 and 69.36 mm at the end of first, second, third, fourth, fifth and sixth years of age, respectively. Density of clams ranged from 2 ind. m−2 (June, July and August) to 8 ind. m−2 (December). Biomass (total weight) of clams ranged between 10.084 g m−2 (August) to 185.100 g m−2 (December). Total mortality (Z) for D. scortum was 3.20 year−1. Natural mortality (M) and fishing mortality (F) were 0.64 year−1 and 2.56 year−1 respectively. Exploitation level (E) was computed as 0.80, indicating that the fishery of D. scortum in the coastal waters of Karnataka is overexploited.

为了管理软体动物资源，需要了解各种种群参数和楔形蛤种群的开发水平。在亚洲，楔形蛤Don（Donax scortum）的种群动态还未知。FAO-ICLARM种群评估工具（俗称FiSAT）用于计算该物种的种群参数。的试样D. scortum从Padukere沙滩收集每隔一个月从2009年2月至2010年1月渐近长度（大号 α）中的溶液70.88毫米和生长系数（ķ）估计为0.64年-1。角皮果蝇达到的大小在第一，第二，第三，第四，第五和第六岁年龄结束时分别为33.51、51.17、60.49、65.40、67.99和69.36毫米。蛤的密度范围为2 ind。m -2（六月，七月和八月）至8 ind。m -2（12月）。蛤的生物量（总重量）在10.084 gm -2（八月）至185.100 gm -2（十二月）之间。D. scortum的总死亡率（Z）为3 . 20年-1。自然死亡率（M）和捕捞死亡率（F）分别为0.64年-1和2.56年-1。开发水平（ē）被计算为0.80，表明在卡纳塔克邦沿海水域的D. scortum渔业被过度开发。
