%X The determination of toxicity is still an important and determining tool for the studies of environmental quality of marine sediments, as well as for the selection of the sites to harvest marine species within the fishing industry. The present paper shows the assessment of nine extracts of superficial sediment, collected from nine stations that were selected from the Cauto Hydrological Basin in the Guacanayabo Gulf, Granma province, Cuba. Toxicity was determined by means of the toxicity assay with Artemia franciscana in 48 hours, according to the methodology of the Mexican regulation , NMX-AA-110-1995-SCFI (1996), adapted to the Cuban conditions. The results showed a significant toxicity in the sediments of the area of Yarey, Cauto river, in relation to control, the group four resulting in a survival rate of 96%, group five with 80%, and group six with 50%, at the different concentrations. During the bioassay potassium dichromate (K2 Cr2O7) was used as positive control of reference, which behaved in the ranged reported in the literature. The results paved a new way for the use of this organism in the assessment of the quality of the Cuban sediment.
