Species composition and distribution of decapod crustaceans in the waters off Patagonia and
SUMMARY: This paper comprises the decapod crustacean material collected during the “Victor Hensen ” campaign 1994 and during the last phase of “Polarstern ” cruise ANT XIII/4 in 1996. Sampling covered waters of medium and greater depth in the Straits of Magellan, the channels towards the south, and...

Sampling covered waters of medium and greater depth in the Straits of Magellan, the channels towards the south, and the area south of the Beagle Channel including the northern slope of the Drake Passage. 30 species of decapods were found, which is considered a good result taking into account that the species restricted to the intertidal and the upper subtidal, which were not subject of this study, are missing. Anomurans were the dominant group, followed by brachyurans and caridean shrimps. Additionally one palinuran (Stereomastis suhmi; n=8) and a single specimen of the astacuran Thymops birsteini were found. Dominance patterns changed considerably from the Straits of Magellan to the channel system south of the Strait, and again to the area south of the Beagle and the northern slope of the Drake Passage. Among the top dominants were the galatheid Munida spp., which in the southernmost area numerically contributes>90 % to the catches, the brachyuran crabs Peltarion spinosulum and Eurypodius latreillii, the her-mit crab Pagurus comptus, and the caridean shrimps Austropandalus grayi and Pasiphaea acutifrons. Munida spp. and P. spinosulum also revealed the highest frequency of occurrence at 49 % and 45 % of the stations, respectively, followed by E. latreillii, P. comptus, and A. grayi. Regional and bathymetric distribution of the principal species are given. The depth range Text Drake Passage Unknown Drake Passage Patagonia |
