Evaluation of the status of barndoor skate in U. S. waters relative to the five listing factors of the ESA led to the conclusion that “there was no evidence that they were in danger of extinction or likely to become endangered within the foreseeable future throughout all or a significant portion of its range.” (Northeast Fisheries Science Center 2000). [...] The distributional patterns for each survey are depicted in Appendix 1. Summer Survey of the Scotian Shelf The summer survey is the longest running survey series in the Maritimes region. [...] In 1986 the survey was expanded to cover the entire bank and the geographic scope of the survey has remained unchanged to present. [...] The few barndoor skate captured during these surveys were located in the deep waters of Cabot Strait (Figure 20) and the slope waters of the Laurentian Channel (Figure 21). [...] The percent occurrence during 1947-1970 was relatively high (270 sets with barndoor skate out of 9888 or 2.7%) due, in part, to the inclusion of the Scotian Shelf in the surveys for those years.
