Examination of the bioindicator potential of Oncholaimus campylocercoides (Oncholaimidae, Nematoda) from Bizerte bay (Tunisia)

Our results demonstrated that biometry, life cycle and fecundity are useful indices to biomonitor hydrocarbon pollution in marine ecosystems. Juveniles of the second and third stage and gravid females of O. campylocercoides seem to be the most appropriate bioindicators.
