Laburpena: The feasibility of using lab-cultured amphipods Corophium multisetosum (Stock 1952) to evaluate the toxicity of contaminants present within marine sediments was studied. This was done by comparing the sensitivity of lab-cultured amphipods in a cadmium toxicity test and to toxic sediment samples, during a 10-days bioassay, with field collected individuals. Different responses were observed between field and cultured individuals. Cadmium test indicated high temporal variability in the LC(50) values of field amphipods (2.40-6.55 mg L(-1)). Sensitivity of cultured amphipods was within the seasonal range of the field individuals (5.81 mg L(-1), LC(50)). However, culture amphipods showed much lower sensitivity in toxic sediment samples. Our results indicate that sensitivity should be determined using a sediment matrix, if the assessment of toxicity is based upon bioassays performed with cultured burrower-amphipods.
