Recently, the depletion and increased regulation of shallow-water fishery r
esources have generated greater interest in the potential of deepwater fish
eries. Smaller-scale fisheries for deep-sea animals have been conducted in
certain locations around the world for more than a century, but large-scale
commercial deepwater fisheries are a more recent phenomenon An examination
of past and current deepwater fisheries shows what we can expect from the
development of new fisheries targeting unexploited deep-sea resources. Prev
ious deepwater fisheries exhibit a pattern of rapid development, depletion
of the resource, and very slow recovery. If future deepwater fisheries are
to avoid this fate, development of new fisheries will require a better unde
rstanding of the resource, its relationship to the environment, and a preca
utionary approach to resource management.
