每个鱼类物种需要不同的栖息地履行其生命功能。一个物种的不同的生命阶段需要有不同的栖息地与之相适应。鱼类典型的生命功能,包括进食,休息,规避天敌和产卵。
根据他们所需要的水的温度,鱼的种类可分为三大鱼类群落:冷水,凉水和温水。但是,这些群落之间存在着一些重叠的区域。例如,在夏天安大略省水温最高的时候,我们会发现一些冷水鱼类生存在凉水鱼类或温水鱼类的栖息环境,这种情况并不罕见。
以下是典型的安省鱼种分类:
温水类(Warm Water Species):Bluegill, Bowfin, Brown Bullhead, Carp, Channel Catfish, Goldeye, Largemouth Bass, Pumpkinseed, Smallmouth Bass, White Bass, White Perch
凉水类(Cool Water Species):Black Crappie, Freshwater Drum, Mooneye, Muskellunge, Northern Pike, Rock Bass, Sauger, Walleye, White Crappie, White Sucker, Yellow Perch
