摘要
于1995年6－9月间在施肥鱼贝混养生态系中，实验研究了搭配养殖菲律宾蛤仔对浮游生物的效应和浮游生物对菲律宾蛤仔养殖的影响。在浮游生物群落构成方面，菲律宾蛤仔使蓝藻、甲藻和浮游挠足类显著减少。对生物量和初级生产力的影响程度与养殖密度有关，而浮游生物丰度和初级生产力在时间上的变化又与营养盐有关。贝类对浮游生物群落结构和初级生产力的影响可以在一定程度上改善水质。浮游生物丰度和初级生产力与菲律宾蛤仔生产量和养殖生物对氮的利用率呈显著的正相关关系。此结果也表明，在该生态系中贝类生产主要依靠牧食链。
Studies on the interaction between Venerpis (Amygdala) philippinarum and plankton in fish-shellfish polyculture ecosystem with fertilizers was carried out from June to September 1995.The effects of the shellfish on plankto showed tha the boimass of cyanophyta, pyrrophyta, copeditecopepode adult and rotifera deereased in community composition, primary production and biomass abundance of plankton decreased with the increase of shellfish density, and changes of those with the nutrition. The effect of the shedrish on community struture and biomass of plankton will improve seawter qulity. Reationships between daily production and utilization ratio of nitrogen of Venerupis(Amygdala) philippinarum and primary prodction, and biomass of plankton were sighficant positive. The results indicate that the production of the shellfish depended maiuly on algae-based grazing chain.
