Radioimmunoassays indicated that T3 ranged from 0.26 to 1.55 μg dL –1 , whereas T4 varied from 52 to 203 μg dL –1 . Adult crabs demonstrated higher levels of T3 than juveniles, while juvenile crabs had higher levels of T4 in comparison to larger conspecifics. The thyroxine levels were consistent throughout the study period. In contrast, significant seasonal variations were found for T3. In immature crabs, the maximum concentration was found in October, whereas in adult crabs, the highest level of T3 was registered in August. Most likely, these results are explained by changes in physiological conditions of the crabs associated with their molting calendar and migration activity. Our data may have important implications for aquaculture of Paralithodes camtschaticus in the Barents Sea.

Only a few studies have reported the presence and levels of thyroid hormones in invertebrates.
