In June 2018 the New Zealand Department of Conservation classified the birdbeak dogfish as "Not Threatened" under the New Zealand Threat Classification System.[3]
A study published in the Journal of the Marine Biological Association of the United Kingdom evaluated the reproductive strategy of the female deep-water shark birdbeak dogfish. This research article discovers that there is a close relationship that exists between Hg level of pregnant females and the Hg level of their embryos, which indicates that there is a transfer of mercury from maternal sources. Therefore, there is a matrophoric strategy for the birdbeak dogfish that are ovoviviparous.[4]
With the rise of fisheries, the birdbeak dogfish is being consumed at higher rates. It has been found to be a good source of minerals, such as potassium and sodium. However, there have been health risks associated with frequent consumption of female dogfish.[5]
