The Antarctic toothfish (Dissostichus mawsoni, Norman) is a large notothenioid fish that supports valuable fisheries around the Antarctic continent. The Ross Sea fishery, which started in 1997, is managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). Whilst a large amount of research into the biology of this species(More)
Ling and hake are tertiary consumers, and as a result both may have an important structuring role in marine communities. The diets of 2064 ling and 913 hake from Chatham Rise, New Zealand, were determined from examination of stomach contents. Ling was a benthic generalist, and hake a demersal piscivore. The diet of ling was characterised by benthic(More)
Both Macrourus caml and M. whitsoni are probably abundant and widespread in the Ross Sea region at depths between approximately 500 and 2100 m. We present the analysis of stomach contents (including regurgitated stomach contents) from an undifferentiated mixture of 33 specimens of these species (henceforth Macrourus spp.) in the Ross Sea region of the(More)
Squaliforme sharks are a common but relatively vulnerable bycatch in many deep water fisheries. Eleven species of squaliforme shark are commonly caught at depths of 200-1200 m on Chatham Rise, New Zealand, and their diversity suggests they might occupy different niches. The diets of 133 Deania calcea and 295 Squalus acanthias were determined from(More)
Diets of 8 rarely sampled species of grenadiers were examined from the lower continental slope (1178 to 1837 m) on Chatham Rise, New Zealand and includes the first known records of the diet of Bathygadus cottoides, Coryphaenoides mcmillani, C. murrayi, and Idiolophorhynchus andriashevi. Most species fed benthopelagically on small crustaceans, e.g., calanoid(More)
We respond to comments made in the opinion paper by Ainley et al. (Hydrobiologia, 10.1007/s10750-015-2607-4, 2016) 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;(More)
This report explores how data structures known as tensors can be used to perform multidimensional data analysis. If a matrix can be thought of as a two-dimensional array, then a tensor can be thought of as a multi-dimensional array (with more than two dimensions). Tensor decompositions are algorithms and tools that can allow the user to directly perform(More)
