Abstract
Dynamics of changes in glucocorticoid (hydrocortisone and corticosterone) levels was studied in the ontogenesis of freshwater crawfish Astacus leptodactylus Esch. It was shown that steroid concentrations increase during the embryogenesis period. Decrease in the glucocorticoid levels during postembryonic development is most probably related to the stabilization of young fish growth and the attainment of hormone levels typical for adult individuals.
The correlation of glucocorticoid levels with physiological-biochemical changes at different stages of ontogenesis indicates that these steroids play an essential role in the regulation of freshwater crawfish vital functions.
