Response to the opinion paper by Ainley et al.

We respond to comments made in the opinion paper by Ainley et al. (Hydrobiologia, 10.1007/s10750-015-2607-4, ) regarding our recent publication on the biology, ecology and life history of Antarctic toothfish ( Dissostichus mawsoni) in the Ross Sea region. We focus in particular on the spatial and temporal extent of data collected from the fishery; results of research to date on changes in abundance and size of Antarctic toothfish at McMurdo Sound; and the subject of neutral buoyancy and inferences about vertical distribution. We conclude by re-iterating the need for well-designed, standardised research programmes to address remaining uncertainties in its life history. [ABSTRACT FROM AUTHOR]
