The reproductive features of the giant red shrimp, Aristaeomorpha foliacea, were investigated in the southern Tyrrhenian sea by experimental trawl sampling. The annual length-frequency distribution showed a multimodal trend in females, ranging between 16 and 67 mm carapace length (CL), and a unimodal trend in males (18–45 mm CL). Mature males occurred in different proportions all year round, while females displayed seasonal maturity (June—September), with a peak in July. Six oocyte developmental stages were identified, the most advanced of which (Pv, postvitellogenic) had never been described before in this species. Ovary development followed a group-synchronous pattern, with the yolked oocyte stock clearly separated from the reservoir of unyolked oocytes, suggesting that A. foliacea is a total spawner, with determinate fecundity. Based upon histological findings, a revision of macroscopic maturity staging employed in Mediterranean bottom trawl surveys (MEDITS) is proposed.

Following the recent expansion of the Brazilian fishery to slope fishing grounds, a new directed trawl fishery for aristeid shrimps emerged since mid 2002. Aristaeopsis edwardsiana has been the main component of the catches attaining 88.4% of total shrimp production. Aristaeomorpha foliacea and Aristeus antillensis have composed significantly smaller fractions of the landings (9.8 % and 1.8 % respectively). Two main grounds were located in the southeastern region (ca. 19º - 25ºS) and one in the northern border of the Brazilian EEZ (ca. 4º30' - 5ºN). Catches have been extremely concentrated between the 700 and 750 m isobaths. Mean catch rates of A. edwardsiana oscillated between 6.5 and 9.7 kg.h-1. The other species have been caught at considerably lower rates (0.1 - 0.6 kg.h-1 and 0.1 - 1.3 kg.h-1, respectively). A seasonal pattern in A. edwardsiana catches is suggested, with maximum values obtained between July and December. While largely directed to the shrimps, incidental catches of the royal crab (Chaceon ramosae) attained, on average, 22 % of the total landings.

Aristaeopsis edwardsiana é um camarão de profundidade registrado em profundidades que variam de 400 - 900 m. Na costa Brasileira, esta espécie compreende um dos mais valiosos recursos pesqueiros. Ao examinar a dieta de Aristaeopsis edwardsiana foi encontrado resíduos plásticos no estômago de três indivíduos. Os espécimes foram capturados através da pescaria industrial de arrasto de fundo no talude da costa de São Paulo (Sudeste do Brasil). Este parece ser o primeiro registro de ingestão de resíduos plástico por esta espécie.; Aristaeopsis edwardsiana is a deep-sea shrimp registered at depths from 400 - 900 m. By examining the diet of Aristaeopsis edwardsiana was found that three individuals had plastic debris on their stomachs. This appeared to be the first record of ingestion of plastic debris by this species.

The Brazilian Aristeidae are reviewed and shown to be represented by the following species: Aristaeomorpha foliacea (Risso, 1827); Hepomadus tener Smith, 1884; Plesiopenaeus edwardsianus {Johnson, 1867); Benthesicymus bartletti Smith, 1882; Gennadas brevirostris Bouvier, 1905; and Bentheogennema intermedia (Bate, 1888). Of these, A. foliacea, H. tener, B. bartletti and G. brevirostris are new records for Brazil. All of the species are widely distributed in the Atlantic and Indo-West Pacific oceans. Gennadas brevirostris is restricted to the Atlantic and Hepomadus tener occurs in the Western Atlantic and Indo-West Pacific oceans. Bentheogennema intermedia is the only species recorded for the Eastern Pacific. The latitudinal distribution among them ranges between 50°N and 40°S.
