Effects of 2,4-dinitrotoluene exposure on enzyme activity, energy reserves and condition factors in common carp (Cyprinus carpio)

► Biochemical effects on carp growth by 2,4-DNT exposure were quantified. ► Enzyme expression, energy reserves, and morphological indices can reflect the molecular targets of 2,4-DNT. ► Identify a trade-off between metabolic cost of toxicant exposure and processes vital to the survival of carp.
