摘　　要：为评价浅海高密度、规模化浮筏养殖贝类的生物沉积作用及其环境生态效应,本文运用生物沉积物捕集器对长海海域浮筏养殖虾夷扇贝的生物沉积速率进行了四个季度的现场测定。结果表明,同一养殖区不同排筏虾夷扇贝的生物沉积速率有很大不同,呈现出由低排筏到高排筏逐渐降低的趋势;不同季节虾夷扇贝生物沉积速率变化明显,秋季最高,冬季最低。海水中悬浮颗粒物浓度及水温是影响扇贝生物沉积速率的主要因素。The bio-deposition rates of suspension fanned Japanese scallop Patinopecten yessoensis in Changhai sea area were determined in situ by the sediment traps in spring, summer, autumn and winter in order to evaluate bio-deposit loading from the suspension aqua- culture system of bivalves. The results showed that the bio-deposition rates of Japanese scallop decreased from inner to outer rafts. The seasonal variations in bio-deposition rates of scallops were found and the highest and lowest rates appeared in autumn and winter, respectively. The results showed that total particulate matters in seawater column and water temperature were main factors to affect the bio-deposition rates of this species.
