  abstract = {{T}he objectives of this study were (1) to assess the responses of benthic nematodes to a polycyclic aromatic hydrocarbon ({PAH}) contamination and (2) to test bioremediation techniques for their efficiency in {PAH} degradation and their effects on nematodes. {S}ediments with their natural nematofauna communities from {B}izerte lagoon ({T}unisia) were subjected to a {PAH} mixture (100 ppm) of phenanthrene, fluoranthene, and pyrene during 30 days. {N}ematode abundance and diversity significantly decreased, and the taxonomic structure was altered. {R}esults from multivariate analyses of the species abundance data revealed that {PAH} treatments were significantly different from the control. {S}pirinia parasitifera became the dominant species (70 % relative abundance) and appeared to be an "opportunistic" species to {PAH} contamination while {O}ncholaimus campylocercoides and {N}eochromadora peocilosoma were strongly inhibited. {B}iostimulation (addition of mineral salt medium) and bioaugmentation (inoculation of a hydrocarbonoclastic bacterium) were used as bioremediation techniques. {B}ioremediation treatments enhanced degradation of all three {PAH}s, with up to 96 % degradation for phenanthrene resulting in a significant stimulation of nematode abundance relative to control microcosms. {N}evertheless, these treatments, especially the biostimulation provoked a weak impact on the community structure and diversity index relative to the control microcosms suggesting their feasibility in biorestoration of contaminated sediments.},
