| 摘 要： | Ecological adaptation and ecological groups of pelagic ostracods were examined in the East China Sea （23°30′-33°00′N, 118°30′ -128°00′E）, in relation to temperature and salinity. The data were collected in four surveys conducted from 1997 to 2000. The density, yield density, or negative exponent models were used to determine the optimal temperature and salinity of water for the thriving growth of pelagic ostracods. Thereafter, ecological groups and potential distribution patterns of pelagic ostracods were determined based on the predicted parameters such as optimal temperature and salinity, consulting the geographic distribution. The analytical results indicate that, among the numerical dominant pelagic ostracods in the East China Sea （ECS）, Euconchoecia aculeata, E. elongata, E. chierchiae, E. maimai, and Cypridina dentata, etc. are offshore subtropical water species. These species are widely distributed in the area, and they can be brought by the warm current to north offshore during spring and winter. The predicated optimal temperature （OT） and optimal salinity （OS） for Paraconchoecia decipiens, P. echinata, P. spini- fera, P. oblonga, Conchoecia magna and Porroeciaporrecta are all greater than 25℃ and 34 separately. These species are mainly distributed in the waters of the Kuroshio, the Taiwan Warm Current, and the Taiwan Strait, and therefore are designated as ocean- ic tropical water species. On the other hand, Pseudoconchoecia concerttrica is considered as offshore subtropical water species based on its geographical distribution although its OT is 19℃. The other species, though their OSs are approximately 34 and with OTs ranging from 20° to 25℃, are considered as offshore subtropical water species because they were found to be widely distributed from the South China Sea to the East China Sea.

| Abstract: | Ecological adaptation and ecological groups of pelagic ostraceds were examined in the East China Sea (23°30' ～ 33°00'N,118°30'～ 128°00'E),in relation to temperature and salinity.The data were collected in four surveys conducted from 1997 to 2000.The density,yield density,or negative exponent models were used to determine the optimal temperature and salinity of wa-ter for the thriving growth of pelagic ostracods.Thereafter,ecological groups and potential distribution patterns of pelagic ostracods were determined based on the predicted parameters such as optimal temperature and salinity,consulting the geographic distribu-tion.The analytical results indicate that,among the numerical dominant pelagic ostraceds in the East China Sea (ECS),Eucon-choecia aculeata,E.elongata,E.chierchiae,E.maimai,and Cypridina dentata,etc.are offshore subtropical water species.These species are widely distributed in the area,and they can be brought by the warm current to north offshore during spring and winter.The predicated optimal temperature (OT) and optimal salinity (OS) for Paraconchoecia decipiens,P.echinata,P.spini-fera,P.oblonga,Conchoecia magna and Porroecia porrecta are all greater than 25℃ and 34 separately.These species are mainly distributed in the waters of the Kuroshio,the Taiwan Warm Current,and the Taiwan Strait,and therefore are designated as ocean-ic tropical water species.On the other hand,Pseudoconchoecia concentrica is considered as offshore subtropical water species based on its geographical distribution although its OT is 19～C.The other species,though their OSs are approximately 34 and with OTs ranging from 20° to 25℃,are considered as offshore subtropical water species because they were found to be widely distribu-ted from the South China Sea to the East China Sea. |
