Sex-related differences in the organismal and cellular stress response in juvenile salmon exposed to treated bleached kraft mill effluent

摘要: Exposure of fish to stressors can elicit biochemical and organismal changes at multiple levels biological organization collectively known as stress responses. The (plasma glucose cortisol levels) cellular (hepatic hsp70) responses in have been studied several species, but little is about sex-related differences these In this study, we exposed sexually immature juvenile chinook salmon (Oncorhynchus tshawytscha) bleached kraft mill effluent (BKME: 0%, 1%, 10% v/v) for 30 days then measured components their Males 1% BKME had higher plasma than females. Plasma were unaffected females BKME, males significantly relative non-exposed males. While exposure did not affect hsp70 males, groups. Within any given treatment, This study demonstrates that exist commonly used indicators fish, points out the importance considering sex research.
