Review of Winter Skate (Leucoraja ocellata) in the Northern Gulf of St. Lawrence in support of a recovery potential assessment / Johanne Gauthier and Claude Nozères. : Fs70-5/2016-075E-PDF

"In 2005, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) first assessed Winter Skate (Leucoraja ocellata) of the northern Gulf of St. Lawrence (nGSL) as data-deficient. In April 2015, COSEWIC re-assessed Winter Skate and revised population structure by grouping nGSL and southern Gulf of St. Lawrence (sGSL) fish in a new designatable unit (DU), the Gulf of St. Lawrence DU with the status endangered. This re-definition of the DU was mainly based on the spatial distribution of Winter Skate and potential heritable traits that indicate significant adaptations. Compared to other populations, Winter Skate in the sGSL mature at a much smaller size and earlier age, have a much shorter maximum length, occur in shallower and warmer water in summer, and differ in morphological characters (teeth and jaws) related to feeding." - Abstract - p.iv.
