Spatio-temporal trends of longline fishing effort in the Southern Ocean and implications for seabird by-catch
distant-water pelagic fleets began fishing for tuna and tuna-like species in the early 1950s. Along with ... thousands of baited hooks in a day across many kilometres of water. These waters are often used as foraging ... Ocean’s longline fleets on seabird populations, this paper describes the trends in longline effort of the ... major pelagic and demersal fisheries in southern waters.

Preliminary examination of otolith microchemistry to determine stock structure in Antarctic toothfish (Dissostichus mawsoni) between SSRU 88.1C and 88.2H
evaluated using otolith microchemistry techniques. Our aims were to (i) determine whether fish from in ... concentrations in the otolith edge and then to (ii) assess the potential of natal signatures to distinguish ... stocks among these regions. For the elements (Mg, Al and Sr) spatial variation in otolith chemistry was ... shown. This resulted in the correct classification of 63% of fish overall to their original capture ...

Apparent decrease of Weddell seal numbers in the western Ross Sea
molting haul outs in the western Ross Sea: Edisto Inlet- Moubray Bay, northern Victoria Land, and ... Edisto-Moubray as well. The timing of decline, or perhaps spreading (low numbers of seals in more places ... ), is unknown but appears unrelated to changes in sea ice conditions, which was our initial hypothesis ... . We analyzed both historic and satellite-derived ice data but found only an expansion of pack ice in ...
