冰岛扇贝，Chlamys islandica（O.F. Müller）在挪威北方峡湾的3个不同深度（海平面以下2、12和40 m）的悬挂培养中生长。在整个生长季节（3月至9月）的身体和壳增量的软部的增长进行了监测。同时，温度，盐度，水密度，流速，叶绿素，颗粒有机物（POM）和颗粒无机物（PIM）在每个实验深度进行了监测。环境数据和生长数据的分析表明，实验深度之间的生长差异基本上是扇贝营养条件差异的结果，由水柱中PIM和POM之间的关系定义。结果还表明，冰岛扇贝的生长可以显着增加悬浮动物在一个更有利的营养环境比发现在天然扇贝床。
Iceland scallops,Chlamys islandica(O.F. Müller), were grown in hanging culture at 3 different depths (2, 12 and 40 m below the sea surface) in a northern Norwegian fjord. The growth of the soft parts of the body and the shell increment were monitored throughout the growing season (March until September). At the same time, temperature, salinity, water density, current speed, chlorophyll, particulate organic matter (POM) and particulate inorganic matter (PIM) were monitored at each of the experimental depths. Analysis of the environmental data together with the growth data showed that growth differences between the experimental depths were essentially the results of differences in nutritional conditions for the scallops, defined by the relationship between PIM and POM in the water column. The results also showed that growth in Iceland scallops can be increased significantly by suspending the animals in a more favourable nutritional environment than that found on the natural scallop beds.
