The small numbers caught are utilised for human consumption, and possibly also used for oil and fishmeal (5). A more widespread, potential threat is the capture of this species as by-catch (5). As they lie on the bottom, angel sharks are particularly vulnerable to by-catch in trawl fisheries, an activity that has increased in the last 50 years. As a result, numbers of angel sharks have declined dramatically, and have even been declared extinct in the North Sea (1) , cited: Stopwatch Big Book: Tadpole download online It is popular among researchers because of its sensitivity to environmental changes.
