Conservation
Abundances of barndoor skate dropped precipitously in the 1960s and early 1970s, coinciding with the period of intense fishing by foreign factory trawlers. The abundance remained very low through around 1990, but increased nearly exponentially from 1990 to 2005, and have been approaching the levels observed in the 1960s.
Each year, the National Oceanic and Atmospheric Administration (NOAA) estimates current population levels for a variety of aquatic species of special interest, and releases an annual report showing the progress being made to reduce harvesting of overfished species. When a species has been determined to be either overfished or subject to overfishing, the regional fishery management councils are required to develop a plan to correct the problem. In 2006, NOAA published a press release stating that as a result of conservation efforts, between 2004 and 2005, monitored stocks of the barndoor skate had grown to a level that the NOAA no longer considers "overfished".[13]
