Sublethal effects of propiconazole on the metabolism of lambari Deuterodon iguape (Eigenmann 1907), a native species from Brazil

The objective of this study was to analyze the sublethal effects propiconazole on Deuterodon iguape, a native fish common in Brazil, which has potential for aquaculture and use as bioindicator. hypothesis test whether D. iguape metabolism similar Danio rerio so that its bioassays may be validated. Lethal concentration (LC50) metabolic rates were studied exposed propiconazole. Specific oxygen consumption ammonia excretion increased by 0.01 µg L?1 then decreased increased. decrease averages specific at 0.1 represented reduction rate compared control 71% 40% rerio. For excretion, same concentration, there 68.7% 45.4% rerio, respectively. When comparing two species each propiconazole, significant difference (p < 0.05) relation highest (0.1 L?1). As consumption, statistically only L?1. proved good useful bioindicator ichthyologists or ecologists studies moderate pesticide contamination freshwater aquatic environments, response
