Freshwater Fish Drawings & Dimensions

Freshwater fish are fish that spend some or all of their live in water with a salinity level lower than .05%. Freshwater fish, due to the segmented nature of ponds, lakes, and rivers, are subject to speciation similar to species on islands.

淡水鱼类是指那些在其生命周期的某些阶段或全部阶段生活在盐度低于0.05%的水体中的鱼类。由于池塘、湖泊和河流的分割性质，淡水鱼类面临着类似于岛屿物种的物种分化。
