Turbulence is common in marine waters. Turbulence can affect the thickness of micro-boundary layer surrounding an algal cell, and therefore affects the gradient of nutrients across the micro-boundary layer. The gradient would determine uptake of nutrients, and hence the growth rate. Ten algal species were studied, including Nitzschia closterium, Skeletonema costatum, Prorocentrum dentatum, Fibrocapsa japonica, Heterosigma akashiwo, Platymonas subcordiformis, Platymonas helgolandica var Tsingtaoensis, Pyramimonas sp. Pyramidomonas, Phaeocystis spp, and Prymnesium patelliferium. It is found that the growth rates of those species were significantly influenced by 100r•min?1 stirring (P<0.05). Little effect was found in green algae growth. The 100r•min?1 stirring enhanced the growth of Phaeocystis spp and Prymnesium patelliferium, stimulated these species to reach a higher maximum biomass than under no-stirring condition, and prolonged the growth time of algae before reaching the maximum. The 100r•min?1 turbulence reduced the growth of Nitzschia closterium, Skeletonema costatum, Prorocentrum dentatum, and Fibrocapsa japonica. Different algae have different responses to turbulence, and it is believed that turbulence is an important factor in phytoplankton interspecies competition.
