摘要
新不伦瑞克省莫里斯湖(Morice Lake, New Brunswick)平生椭圆藻(Elliptio compplanata, Lightfoot)的数值密度为15.92±1.24/m2，有机质存量为10.69 g/m2。年产量为2.14克/平方米/年，主要产自组织(69.6%)、有机壳材料(27.6%)和glochidia(2.8%)。相对于其他种群的高年产量被认为是高数量丰度的反映，这是由于在适当深度有高可用性的适当底物加上足够的鱼类宿主种群。
Biomass and Production of the Unionid, Elliptio complanata (Lightfoot) in an Old Reservoir in New Brunswick, Canada
In Morice Lake, New Brunswick, Elliptio complanata (Lightfoot) has a numerical density of 15.92± 1.24/m2 and an organic matter standing stock of 10.69 g/m2. Annual production of 2.14 g/m2/y is divided amongst tissue (69.6%), organic shell material (27.6%) and glochidia (2.8%). The high annual production relative to other populations is thought to be a reflection of the high numerical abundance which results from the high availability of suitable substrates at appropriate depths coupled with adequate fish host populations.
