Decadal 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 (CPUE) were derived from the >5500 fish caught. Contrary to expectation, length19 frequency was dominated by fish in the upper half of the industrial catch. The discrepancy may 20 be due to biases in the sampling capabilities of vertical (this study) versus benthic (horizontal) 21 https://ntrs.nasa.gov/search.jsp?R=20120010315 2017-09-14T03:08:58+00:00Z
