【 摘 要 】

This work determined the best survival conditions for the clam Mytella guyanensis and the mussel Perna perna in the estuary and sea aquaria respectively over at least 12 days, which could enable their use in the ecotoxicological studies. The aquaria were set up with the appropriate water and sedimen, and allowed to establish for a minimum of one month before adding the organisms. The best survival conditions for M. guyanensis required more time for the aquarium stabilization, addition of inocula and more frequent water changes than for P. perna. The organisms' lipid contents increased and their condition index was maintained indicating the good conditions of the aquaria, hence, their possible use in the sub-chronic studies.
