摘　　要：研究了亚心形扁藻Platymonas subcordiformis、小球藻Chlorella sp.对网纹藤壶Balanus reticulatus幼虫发育和附着的影响。结果表明,在幼虫存活率以及金星幼虫和Ⅵ期无节幼虫所占比例方面,旺盛期亚心形扁藻对网纹藤壶幼虫的投喂效果均明显优于小球藻;旺盛期亚心形扁藻培养的金星幼虫附着率明显高于老化扁藻(p<0.01)。因此,以旺盛期亚心形扁藻作为幼虫培养饵料应更有利于藤壶幼体的生长发育。This paper deals with the effects of Platymonas subcordiformis and Chlorella sp. on larval growth and settlement of barnacle Balanus reticulatus. We found Platymonas subcordiformis was obviously superior to Chlorella sp. as the diet in terms of larval survival rate and ratio of cyprids and Stage Ⅵ nauplii. As for the larval settlement rate, Platymonas subcordiformis during exponential phase was much better source of diet than that during decline phase. Therefore, it is more efficient to use Platymonas subcordiformis in exponential phase as the diet for larval culture of barnacle Balanus reticulatus.
