Abstract(s)

Estimates of the condition of aquatic organisms can be used to monitor the health or recovery of aquatic areas, under the ecohydrologic approach (Zalewski 2000, Chicharo et al. 2001). The ability of aquatic organisms to cope with environmental stress may be expensive in terms of energy and this cost of tolerance have negative counterparts in growth, reproduction, recruitment, susceptibility to disease, predation and physical disturbance (Jackson et al. 2002, Lloret et al. 2003, Oliva-Paterna et al. 2003). Density-dependent factors such competition and aggression can influence fitness, growth, reproduction, and survival (Hensor et al. 2005, Leitão 2006). Indices of the condition of organisms are valuable for managers of aquatic ecosystems for assessment of the health status of populations (Brown, Austin 1996).
