Description
If crustacean ethoxyresorufin O-deethylase (EROD) activity varies with the molting physiology, then the use of random crustacean EROD activity and whole tissue samples as biomarkers for pollution can be questioned. This study determined if mitochondrial or microsomal EROD activities in the hepatopancreas were affected by the molting physiology in the fiddler crab, Uca pugilator. Intermolt crabs were injected with the exogenous molting hormone 20-hydroxyecdsyone. Results showed a significant increase in mitochondrial EROD activity suggesting that mitochondrial EROD activity is influenced by molting physiology. Only microsomal cell fractions should be used to perform crustacean EROD assays when evaluating aquatic pollution.
