Article Synopsis
- The study focused on creating a method to extract cortisol from sturgeon fins using two solvents, water and isopropanol, and comparing cortisol levels across three sturgeon species: beluga, Siberian, and sevruga.
- Cortisol extraction involved a series of precise steps, including washing samples, air-drying, grinding, and using methanol for extraction followed by analysis with ELISA.
- The findings revealed no significant differences in cortisol levels among the sturgeon species or between fin and jawbone samples, suggesting that jawbone may be a useful stress indicator in sturgeons.
Effects of 11-ketotestosterone and temperature on inhibin subunit mRNA levels in the ovary of the shortfinned eel, Anguilla australis.

Members of the transforming growth factor-b (TGFb) superfamily are important during early oogenesis in mammals. In this study, we tested whether documented effects of 11-ketotestosterone (11KT) on previtellogenic eel ovaries are mediated through affecting the expression of key ovarian TGFb genes. Furthermore, we investigated whether 11KT effects interacted with temperature.

However, the use of aromatizable androgens and the tissue-specific focus of most studies often make it unclear if androgenic effects throughout the axis proceed via androgen or estrogen signalling mechanisms. In this study, we assessed the effects of 11-ketotestosterone (11KT, a non-aromatizable androgen) on the pituitary and ovary of previtellogenic (PV) freshwater eels Anguilla australis, comparing them with eels naturally undergoing early vitellogenesis (EV).
