    Description: Concentrations of scavengers attracted by bait in the deep sea are documented by time-lapse photography and results of baited traps. During a remotely operated vehicle deployment in the Molloy Deep, the deepest depression of the Fram Strait, the carcass of a natant decapod, Pasiphaea tarda Krøyer, 1845, was discovered at 79°08.4'N and 002°49.85'E in a depth of 5,551 m. The carcass was covered by hundreds of individuals of Uristes sp., a scavenging lysianassoid amphipod. After documentation of this event, both the carcass and the majority of amphipods were collected. This is the first reported observation and sampling of an ongoing feeding process of scavengers on a natural food fall in the deep sea.

    Description: Growth, mortality and productivity of the hard clam E. exalbida from Ushuaia Bay, Beagle Channel were investigated. The parameters of the von Bertalanffy growth function were estimated to be H = 73.98 mm, K = 0.180 y 1, t0 = 0.147 y. Maximum individual production amounted to 2.742 g shell free wet mass (SFWM) at 49.5 mm shell height. Animals between 40 mm and 70 mm shell height contribute most to overall population somatic production P of 133.89 g SFWM m-2 y-1. Mean annual biomass B amounted to 1122.69 g SFWM m-2 y-1. Annual P/B ratio and mortality rate Z were estimated to 0.119 y-1 and 0.141 y-1, respectively. Slow growth and low turnover makes this population less suitable for sustainable commercial exploitation.
