Seamounts, sanctuaries and sustainability: moving towards deep‐sea conservation

Seamounts, sanctuaries and sustainability: moving towards deep‐sea conservation P. KEITH PROBERT* Department of Marine Science, Uni6ersity of Otago, PO Box 56, Dunedin, New Zealand KEY WORDS: seamounts; deep-sea conservation; fishing impacts FISHING IMPACTS The open ocean is under intense pressure, especially from fishing and fishing-related activities. Many deeper water fishing grounds have been exploited as a result of the depletion of many inshore stocks, the improvements in fishing technology and the development of a new international regime for the oceans (Hinds, 1992). There is also growing concern over the wider impacts of fishing (Dayton et al., 1995; Botsford et al., 1997; Goni, 1998; Hall, 1999), including the disturbance of the seabed and benthos by Ëœ bottom trawling. Watling and Norse (1998) have likened the effect of bottom trawling on the seabed to forest clearcutting by sharply reducing structural diversity and dependent biota. Such impacts have been described mainly for shelf areas (e.g. De Groot, 1984; Hutchings, 1990), but the effects of fishing gear on the seabed are likely to be most severe in deeper water where the life-history characteristics of species generally indicate that recovery may be measured at least in decades (Jones, 1992; Watling and Norse, 1998).
