The contents of ions in the blood have been compared in three ecological groups of brown trout (parr, mature, and resident) living in rives of the basins of Lake Onega and Lake Ladoga. Brown trout from the Alats-oya (the Ladoga basin, remote from two other rivers belonging to the Onega Lake) is characterized by the lowest concentrations of the Na, Ca2, and Cl ions in blood. The probable effect of the ion level in blood of brown trout on selection of life strategy is discussed.
对生活在奥涅加湖和拉多加湖流域河流中的三组生态型褐鳟(幼鱼、成鱼和定居鱼)的血液离子含量进行了比较。来自阿拉特索亚河(拉多加湖流域,远离属于奥涅加湖的另外两条河流)的褐鳟血液中钠、钙离子和氯离子的浓度最低。文中讨论了褐鳟血液中离子水平对生活策略选择可能产生的影响。
