title: [Changes in the content of 11-oxycorticosteroids in the blood serum of the spawning Siberian salmon Oncorhynchus keta and humpback salmon Oncorhynchus gorbuscha].
abstract: Studies have been made on 11-oxycorticosteroid content of the blood serum in spawning salmons. During sexual maturation and spawning migration, the level of 11-oxycorticosteroids in the blood serum undergoes significant changes. The pattern of these changes is similar in both of the species investigated. During fresh-water period of migration, 11-3xycorticosteroid content in the blood serum of females of O. gorbuscha is 3 times higher as compared to that during sea-water period. In O. keta, this level increases two-fold. The increased content of 11-oxycorticosteroids remains constant up to spawning. After the latter, the level of 11-oxycorticosteroids decreases reaching the values typical for sea-water period.
