在高浊度、潮汐差达5 m的温带河口上游进行了1年的鱼类和甲壳类取样。样品取自Doel核电站（Zeeschelde，比利时）的冷却水回路。1994年7月至1995年6月期间，共录得55种鱼类、2种虾类和4种蟹类。鱼类群落由36种海洋鱼类、16种淡水鱼类和3种双栖鱼类组成。虾类、虾蛄科和虾蛄科在数量和生物量上均占主导地位。物种组成具有明显的季节演替特征。有人认为，幼鱼和甲壳类动物将高度浑浊的泽斯谢尔德河口作为躲避捕食者的避难所。(C) 1998学术出版社。
Fish and crustaceans were sampled for 1 year ic the upper reaches of a temperate estuary characterized by high turbidity and a tidal range of up to 5 m. Samples were taken in the cooling-water circuit of the Doel Nuclear Power station (Zeeschelde, Belgium). Between July 1994 and June 1995, 55 fish species, two shrimp species and four crab species were recorded. The fish community was composed of 36 marine species, 16 freshwater species and three diadromous species. Shrimps, Gobiidae and Clupeidae dominated the samples both in numbers and biomass. An exceptionally clear seasonal succession was observed in the species composition. It is argued that young fish and crustaceans use the highly turbid Zeeschelde Estuary as a refuge from predators.
