Trophic contamination by pyrolytic polycyclic aromatic hydrocarbons does not affect aerobic metabolic scope in zebrafish Danio rerio

International audienceThe effect of trophic exposure to pyrolitic polycyclic aromatic hydrocarbons (PAH) on aerobic metabolism on zebrafish Danio rerio was investigated. There were no significant differences in standard metabolic rate (SMR), active metabolic rate (AMR) or aerobic metabolic scope (AS) at any sub-lethal concentration of PAH in the diet of adult or juvenile zebrafish. This suggests that under these experimental conditions, exposure to PAH in food did not influence aerobic metabolism of this species
