Abstract/Description: The channelized Kissimmee River experiences seasonally low dissolved oxygen levelswhich have changed the ecosystem to favor air-breathing species, while gamefishpopulations have declined greatly. In 2001 , the central portion of the river (Pool C) wasphysically restored.To evaluate the usefulness of various stress markers and assess the success of the partialrestoration, the stress responses were analyzed (brain monoamines, heat shock proteins,and plasma cortisol) of air-breathing fish (bowfin, Florida gar), versus gamefish(largemouth bass and bluegill sunfish). Fish were collected from hypoxic and normoxicwater at three sites in the Kissimmee River. Statistical analysis (MANOV A) showedoverall significantly higher stress response in hypoxic gamefish than those in normoxia,with higher hsp72 levels, DOPAC, and Dopamine turnover (DOPAC:DA). Hsp60 andcortisol was significantly higher only in hypoxic bass while serotonin and 5-HIAA weresignificantly higher in hypoxic bluegill sunfish. Air-breathers did not show higher stresslevels during hypoxia.
