Decadal trends in abundance, size and condition of Antarctic toothfish in McMurdo Sound, Antarctica, 19722011
We report the analyses of a dataset spanning 39 years of near-annual fishing for Dissostichus mawsoni in McMurdo Sound, Antarctica, 1972–2011. Data on total length, condition and catch per unit effort (CPUE) were derived from the > 5500 fish caught, the large majority of which were measured, tagged and released. Contrary to expectation, the length frequency of the McMurdo Sound catch was domina...
متن کاملDecadal Trends in Abundance , Size and Condition of Antarctic Toothfish in Mcmurdo 1 Sound , Antarctica , 1972 - 2010
14 We report analyses of a dataset spanning 38 years of near-annual fishing for Antarctic toothfish 15 Dissostichus mawsoni, using a vertical setline through the fast ice of McMurdo Sound, 16 Antarctica, 1972-2010. This constitutes one of the longest biological time series in the Southern 17 Ocean, and certainly the longest for any fish. Fish total length, condition and catch per unit 18 effort...
متن کاملUnnatural Selection of Antarctic Toothfish in the Ross Sea, Antarctica
Historically, fishermen targeted fish in shallow, nearshore waters relatively close to port (Pauly et al. 2005). As these species became depleted, to meet growing demands, fishermen were forced to move offshore and into deeper waters (Hutchings and Reynolds 2004; Koslow et al. 2000; Morato et al. 2006; Hilborn et al. 2003; Pauly et al. 2002, 2005). Steady advances in fishing technology facilita...
متن کاملSoil microorganisms of the McMurdo Sound area, Antarctica.
A study of soil microorganisms of Ross Island and the adjacent mainland was carried out during the brief austral summer of 1961-1962. In some cases, seasonal changes in microbial numbers were observed, although microorganisms could not be detected in some soils. Bacterial species common to temperate regions were isolated from a number of different samples. Thermophilic bacteria were present in ...
متن کاملRapid Change in Shallow Water Fish Species Composition in an Historically Stable Antarctic Environment
McMurdo Sound, Antarctica, is home to a unique marine biota with an ecology that has evolved in this frigid environment over millions of years. The region is one of the least disturbed, and possibly the last pristine, marine ecosystem on Earth. Here, the results of three seasons of fishing in the shallow nearshore waters of McMurdo Sound are reported. A shift in the composition of small fish sp...
