Preliminary assessment of the South Georgia ray populations
from a variety of sources, and included the consideration that since 2004 the practice of cutting rays ... off lines at the water surface should have increased survivorship of discarded rays, although this ... survivorship has been found to decrease as depth of fishing increases. Our analysis is concentrated on catches ... deeper than 800m, and we have assumed that the majority of catches were of the Amblyraja variant species ...
