1987年12月至1988年11月在闽南-台湾浅滩渔场获得83种多毛类，隶属于35科67属。欧努菲虫（Onuphis eremita）、锥唇吻沙蚕（Glycera o-nomichiensis）、拟特须虫（Paralacydonia paradoxa）和滑指矶沙蚕（Eunice indica）等出现频率较高。马氏独毛虫（Tharyx marioni）、奇异稚齿虫（Paraprionospio pin-nata）、多齿全刺沙蚕（Nectoneanthes multignatha）和梯额虫（Scalibregma inflatum）密集地分布于局部水域。闽南-台湾浅滩渔场多毛类年平均生物量为1.13g/m^2，年平均密度为25个/m^2，均低于台湾海峡北部、东山湾湖下带和大亚湾等水域。闽南-台湾浅滩渔场多毛类表现为低多样性特征。这些分布特征取决于底质类型，该海区沉积颗粒较粗，不利于多毛类繁衍。海流和水团也有重要作用。  相似文献   

Spatio-temporal changes of marine macrobenthic community in sub-tropical waters upon recovery from eutrophication. II. Life-history traits and feeding guilds of polychaete community

A two-year study was conducted in the vicinity of a harbour in sub-tropical Hong Kong, to examine the progress of recovery of macrobenthic community, based on analyses of both life-history traits and trophic guilds of polychaetes, upon cessation of organic pollution caused by sewage discharge. Seventy seven out of 83 species collected were classified under four ecological groups based on the life-history traits and sensitivity to organic gradients. The mean ATZI marine biotic index (AMBI) derived from these ecological groups showed spatial difference among the five sampling locations. In particular, the presence of different percentages of polychaete species from Groups III (unbalanced community) and IV (polluted community) suggested the presence of pollution stress in certain degree at all sampling locations. However, no significant temporal changes were noted over the study period. From all polychaete species identified, they were classified into 13 feeding guilds. The mean diversity of these feeding guilds at most of the sampling locations was significantly higher than that at one of the inside-harbour locations. The composition of feeding guilds was also significantly different spatially. At one of the inside-harbour locations, the dominant feeding guilds were motile/discretely motile surface deposit feeders with tentaculates or unarmed pharynx, and motile omnivores with jawed pharynx in the first year of study, but were replaced by motile, jawed carnivores in the second year of study. The increased proportion of carnivores over the study period can be seen as a sign of recovery in the community structure since abundance of predators is commonly higher in habitats with better environmental quality. The implications of using life-history traits and feeding guild analyses for benthic community are discussed.  相似文献
