【摘要】 于1986－1991年，在南海北部对17个海洋结构物进行调查，以了解有柄蔓足类的种类组成、分布状况和个体大小。结果表明，所采集的标本有2科4属8种，它们分别是茗荷属的荷、鹅荷和印度荷；条荷属的细板条荷、条荷和百条荷；软荷属的太平洋软荷及异荷属的日本异荷。荷、鹅荷和细板条荷几乎分布在所有浮标站，其附着密度随着离岸距离的增加而增大；荷和鹅行可分别在0－80m和0－75m水层中分布，而细板条荷则从表层一直分布到150m深处。该类生物属外海性种类，只附着在漂浮或能移动的物体表面，而不栖息于固定式海洋结构物。更多还原

【Abstract】 The species composition and distribution of Lepadomorpha in the northern part of the South China Sea Were investigated from 1986 to 1991. 7 species of Lepa-didae and 1 species of Heteralepadidae were collected from the submerged surfaces of 16 offshore structures (13 biologica1 buoys and 3 Marex hydrological buoys). No samples of Lepadomorpha were obtained on the underwater surfaces of the fixed oil production platform and all sinkers. Lepas anatifera, L. anserifera and Concho-derma virgata were found in almost all stations. Their attaching densities inc-reased with increasing distance from shore. L. anatifera and L. anserifera were found from the waterline to 80 and 75m below sea level, C. hunteri from the sea surface down to 150m depth. The individual sizes of Lepadomorpha collected are also reported in this paper. All these organisms are open sea species which only settle on the submerged surfaces of buoyant or movable objects, and do not attach themselves to surfaces of fixed marine structures.更多还原
