The mesozooplankton from the Straits of Magellan, Chilean channels and fiords and the Beagle Channel have been weel studied in relation to oceanographic and bio-ecological environmental conditions. Different assemblages constituted by a variable proportion of holoplanktonic and meroplanktonic forms have been observed. In comparison, little is yet known of the mesozooplankton from the eastern Beagle Channel and the coastal environments such as Ushuaia Bay and Golondrina Bay, which are two small bays on the northern coast of the Beagle Channel. In this study we present the first results collected on the composition and abundance of the upper layer mesozooplankton in these bays from samples taken during January 2001.
