COMMON NAMES
New Zealand skate
Rough skate (Zearaja nasuta, RSK) ranges throughout coastal waters of North and South islands, and Stewart Is - Snares Islands Shelf, plus scattered records from the Chatham Rise and Campbell Plateau. Depth range from the shore to about 1,000 m but rare deeper than 600 m. Rough skate are fished commercially in New Zealand in close association to smooth skates, which are also known as barndoor skates (Francis 1997). Although rough skates grow considerably smaller than smooth skates, RSK is still landed and processed. Two other species of deepwater skate (Bathyraja shuntovi and Raja hyperborea) are large enough to be of commercial interest but are relatively uncommon and probably comprise a negligible proportion of the landings (MPI 2011).
In lack of knowledge about the stock structure of New Zealand rough skate, the species is managed according to the five fishstocks (and correspondent fishing management areas): RSK 1 Auckland East (FMA 1, 2); RSK 3 South East Coast, South East Chatham Rise, Sub-Antarctic, Southland (FMA 3, 4, 5, 6) here named as SE New Zealand; RSK 7 Challenger (FMA 7); and RSK 8 Central Egmont and Auckland West (FMA 8, 9) (MPI 2014).
New Zealand rough skate Zearaja nasuta and New Zealand smooth skate Dipturus innominatus are captured in the same multispecies fishery but managed separately (MPI 2014).
