研究了溯河产卵的马苏鲑鱼（Oncorhynchus masou）卵大小和数量的垂直变化。相对较大的变化，卵的大小发生在河流之间比女性在河流或女性。蛋的大小一般较大，蛋的数量一般较低，在更北的纬度。
Latitudinal variation in egg size and number in anadromous masu salmon Oncorhynchus masou was examined. Relatively greater variation in egg size occurred among rivers than among females within rivers or within females. Egg size was generally greater and egg number generally lower at more northerly latitudes.
