Plasma cortisol and glucose concentrations in the striped mullet (Mugil cephalus L.) subjected to intense handling stress

The plasma cortisol and glucose concentrations were determined in mature female striped mullet (Mugil cephalus L.) subjected to short term intense handling stress. The results indicated that plasma cortisol levels reached a peak 20 min after stress and declined gradually afterwards. The highest concentration of plasma glucose was observed 30 min after stress. The present study showed that the rise of plasma glucose was associated with the plasma cortisol levels.
