作为对 Sebastes 属红鱼种间和种内遗传变异更广泛研究的一部分，从挪威水域和冰岛西南海岸附近的几个地点收集了 593 个胎生 Sebastes 个体的样本。分析了血红蛋白和五种多态性酶。观察到一种新的血红蛋白多态性，并在冰岛和挪威样本中发现了独特的等位基因。酶分析的结果与之前的结果基本一致，但 IDHP* 和 Hb* 等位基因的频率观察到群体间差异。与其他 Sebastes 物种相比，胎生 S. viviparus 与来自西大西洋的 S. fasciatus 表现出更高的相似性。
As part of a more extensive study on the inter- and intraspecific genetic variation of redfish, genus Sebastes, a total sample of 593 individuals of the species Sebastes viviparus were collected from several locations in Norwegian waters and off the south-west coast of Iceland. Haemoglobin and five polymorphic enzymes were analysed. A new haemoglobin polymorphism was observed, and unique alleles were found in Icelandic and Norwegian samples. The results of the enzyme analyses were largely consistent with previous results, but interpopulation variation was observed in the frequencies of IDHP* and Hb* alleles. S. viviparus displayed higher similarity with S. fasciatus from the West Atlantic than with the other Sebastes species.
