摘要
根据1997-2000年东海23°30′～33°00′N、118°30′～128°00′E海域4个季节海洋调查资料,对东海管水母类种类组成及优势种、数量分布、生态类群等作了探讨。结果表明:鉴定到种的管水母类有40种,其中宽板无棱水母(Sulculeolariabigelowi)为东海区首次记录;主要优势种有五角水母(Muggiaeaatlantica)、双生水母(Diphyeschamissonis)和拟细浅室水母(Lensiasubtiloides)等。管水母类总丰度春季最高(491ind·10-2·m-3)、夏季最低(66ind·10-2·m-3);平面分布不均匀,一般东海近海高于外海和台湾海峡海域。东海管水母类可分为3个生态类群,数量上以近岸低盐广温类群占优势,65%的种类由广高温高盐类群构成。
Based on the data acquisitioned in the seasonal survey conducted from the seasons of spring through winter in the period of 1997 to 2000 in the East China Sea (23°30′-33°00′N, 118°30′-128°00′E), the community composition and dominant species of Siphonophora as well as its abundance distribution and ecological community in the sea were studied. Forty (40) species of Siphonophora were identified, among which Sulculeolaria bigelowi (Sears) was newly discovered in the sea, and Muggiaea atlantica, Diphyes chamissonis and Lensia subtiloides, etc were classified as dominant species. Most of species were appearing in offsea in the seasons of spring, autumn and winter. In summer season more species were inhabitable inshore water of the southern part of the sea and the most distributed in offsea and the Taiwan Strait. However, in the inshore waters of the northern part of the sea, the number of species became less in the whole year round. As Siphonophora was very susceptible to the temperature and salinity of sea water and its range of adaptability not wide, it was favourable to relatively stable environment of sea water. Both spring and autumn seasons were its distributional seasons, and so Siphonophora was widely distributed in Kuroshio and Taiwan Warm Current in the season of winter, but the distribution was affected by coastal water. The total abundance of Siphonophora in the sea was very low, the highest (491 ind·10-2·m-3) in spring and the lowest (66ind·10-2·m-3) even in summer. Three ecological communities of Siphonophora were composed of in the sea, in which 65% species was high temperature and salinity ones, but the species of offshore low salinity and eurythermality was dominant in abundance.
