As previously reported, little is known of the biology of this dogfish though it is likely to have the limiting life history characteristics similar to other deepwater shark species, thus will not be sufficiently fecund to withstand high levels of exploitation. It occurs on the continental slope off Western Australia with a depth range of 300 to 510 m. This area is subject to the North West Slope Trawl and Western Deepwater Trawl fisheries. Although there has been no assessment of the effect on the non-target bycatch species of these fisheries, which will likely include Squalus nasutus, fishing effort is small with only a few boats in operation. The lack of data on the species? biology, extent of occurrence, population size, or any indicator of population trend warrants a Data Deficient assessment at this time.
