ABSTRACT The deep water red shrimp Aristaeomorpha foliacea is an important commercial species for the trawl fisheries in the Sicilian Channel (Central Mediterranean Sea; FAO statistical area 37.5). An assessment program was recently implemented by ITPP-CNR. Two years of seasonal research trawl surveys were carried out on the Italian side of the Sicilian Channel. A time series of length-frequency distributions has been analyzed using different techniques; the results are used to estimate growth and mortality parameters of the stock. In females, two modal pulses can be discriminated for the juveniles while two-to-three "years" are visible for the adults. Female growth can well be represented by a Von Bertalanffy function: as with other species, too, there are two possible growth hypotheses, slower and faster; A. foliacea females appear to grow relatively fast anyhow. Female total annual mortality (Z) is estimated around 0.65, with
