Barndoor skate biomass averaged 1.07 [+ or -] 0.09 kg per tow, and thorny skate biomass averaged 0.36 [+ or -] 0.15 kg per tow over the study period.
Thorny skate landings were much lower than winter skate but were still comparatively high in 2005 (404 t) and 2006 (409 t), given their prohibited status.
However, the relative abundance of thorny skate also declined during the study period, possibly affecting availability.
Since the sharp decline in thorny skate landings was concurrent with the release of the prohibited species letter by NMFS in 2007, it appears that it may have had a significant effect in improving compliance.
Some aspects of the thorny skate, Amblyraja radiata, reproductive biology in NAFO Division 3N.
Differences in sexual maturity and related characteristics between populations of thorny skate Rajaradiata in the northwest atlantic.
Although no comprehensive published data for reproductive cycles currently exist for thorny skates in the Gulf of Maine, information from the few skate species studied so far indicates that sexual maturity at a late age, low fecundity, and a relatively long life span may also be characteristics of A.
Thorny skates were captured by otter trawl in an area approximately 900 square miles centered at 42[degrees]50'N and 70[degrees]15'W in the Gulf of Maine.

Abstract--The northwest Atlantic population of thorny skates (Amblyraja radiata) inhabits an area that ranges from Greenland and Hudson Bay, Canada, to South Carolina.
Thorny skates were captured by otter trawl in an approximate 900 square mile area centered at 42[degrees]50'N and 70[degrees]15'W in the Gulf of Maine between June 2001 and May 2002.
