Materials of research in the northern part of the Okhotsk Sea were presented. The data were collected in May and June 2016 on a fishing vessel by traditional method used in VNIRO. A random sample was taken from trap catches for biological analysis and a quantitative accounting of commercial species of crabs by size-sex groups was conducted. This methodology allows you to quickly gather information about the biological status and abundance of the adult crabs in population in the fishing area. The data on the relationship between the protein content in the hemolymph of crabs and muscles content of their limb were collected. The results of the research show that the state of the commercial snow crab Chionoecetes opilio in the North Okhotsk and the East Sakhalin subzones can be described as good, and the state of the blue king crab Paralithodes platypus of Eastern Sakhalin population can be described as satisfactory and stable
