The effects of acute handling stress on the secondary stress responses of striped bass (Morone saxtilis) and its hybrid (Morone chrysops x Morone saxtilis)

The importance of understanding the stress response can not be underestimated in fisheries research or the aquaculture industry. Three studies were undertaken to quantify the secondary stress responses of striped bass and its hybrid. These were measured as fluctuations in glucose, glycogen, lactate, and osmolality. Fish were stressed by aerial emersion in a dipnet. The first study was conducted with fingerling inland and anadromous striped bass. The three goals were to: determine if fingerlings responded with the General Adaptation Syndrome, if the two had different responses to the stress, and if feeding state (fed up until the day of the stress vs. starved for three days prior) had an effect on the stress response. The second study was conducted with two-year-old pure and hybrid striped bass. The two goals were to: determine any differences in the stress response, and to see if the feeding state played a role in the response. The third study was conducted with hybrid fingerlings. This study looked at the ability of fed and three-day starved fish to moderate their secondary stress responses after handling stress, when placed in 0, 5, 10, or 15% saline recovery water.
