浮游植物的生长受控于影响细胞内过程的因素，如辐射、营养物质和温度；以及影响整个细胞的因素，如放牧、下沉、混合和平流。为了评估这些因素中的某些因素对生长的影响，短期实验可以接受小型容器，但长期观察建议使用连续培养系统。研究混合浮游植物在多营养系统中的生长需要大规模的设施和非常大的容器。在CEPEX(受控生态系统种群实验)食物网I实验期间，本研究考察了添加大量营养素(硝酸盐、磷酸盐和硅酸盐)对生长在包含多营养群落的大型围栏(1335立方米)中的浮游植物物种的影响(Grice等人。1980年)，加拿大不列颠哥伦比亚省萨尼奇湾。
Phytoplankton growth is controlled by factors that influence intracellular processes, such as radiation, nutrients, and temperature; and factors that influence the entire cell, such as grazing, sinking, mixing, and advection. To evaluate the effects of certain of these factors on growth, small-scale containers are acceptable for short-term experiments, but continuous culture systems are recommended for long-term observations. Examining the growth of mixed phytoplankton assemblages in a multitrophic system requires large-scale facilities and very large containers. The present study examines the effects of macronutrients (nitrate, phosphate, and silicate) additions on phytoplankton species grown in large enclosures (1335 m3 ) containing multitrophic communities, during the CEPEX (Controlled Ecosystem Populations Experiment) Foodweb I experiment (Grice et al. 1980), at Saanich Inlet, British Columbia, Canada.
