萨哈林岛哲罗鱼的每只红鲑鱼都有一个该物种特有的V形锅。每个多卵囊红d的形状是多个单卵囊红d的组合，根据形状可以估计出多卵囊红d中卵囊的数量。假红是小的，没有任何V形的锅。影响redd大小的因素进行了数值检验，因此，卵袋和鸡蛋和女性叉长的数量与尾长显着相关。每个卵囊含卵11-920粒（平均546.7 ± 95%CL 81.9），卵囊深度与雌叉长呈极显著正相关。每只雌性的平均红细胞数为3，估计雌性的数量为红细胞数的三分之一。
Each redd of the Sakhalin taimen Hucho perryi had a V–shaped pot that is specific to this species. The shape of each multiple–egg–pocket redd was a combination of one–egg–pocket redds, and the number of egg pockets in the redd could be estimated from the shape. False redds were small and did not have any V–shaped pots. The factors affecting redd size were examined numerically; consequently, numbers of egg pockets and eggs and female fork length were correlated significantly with tail length. Each egg pocket contained 11–920 eggs (mean: 546·7±95% CL 81·9) and the egg pocket depth was correlated significantly with female fork length. Mean number of redds per female was three, and the number of females could be estimated as one third of the redds.
